    Activity intensifies at Mexico’s Popocatepetl volcano: 19 million could be affected by an eruption
    April 19, 2012 – MEXICO - The Popocatepetl volcano is making movement and threatening to erupt, causing Mexican officials to raise the alert level from yellow phase three to yellow phase two. The volcano has already begun spewing red-hot bits of rock, and its opening has expanded. These are signs that the volcano, still quite active, could soon erupt. In a statement by Mexico’s National Center for Disaster Prevention, the volcano could produce “moderate exhalations, some with ash, sporadic low to moderate explosions with likely burning fragments, and flaming magma within the crater.” Residents and tourists have been advised to remain at least seven miles away from the volcano’s base, lest magma or hot rock injure anyone. Mexico has been experiencing natural disasters with increasing frequency. On Friday, officials at the U.S. Geological Survey reported a 5.4 magnitude earthquake six miles off Mexico’s Pacific Coast. It was powerful enough to shake buildings 230 miles away in Mexico City. Thankfully no one was hurt in that earthquake, and the country was left relatively unscathed. A 7.4 magnitude earthquake hit just two days earlier, again not injuring anyone but leaving Mexico City residents shaken. According to Reuters, it was the third earthquake in less than one month. The last major earthquake struck on March 20, injuring 11 in Oaxaca and two in Mexico. The Popocatepetl volcano last erupted in 2000, and in 2005 it released a high volume of smoke and ash. Lava was also released during 2005, and since then it has remained relatively quiet. Only in 2012 has it begun moving and acting again. Reuters is reporting that several schools have closed in light of the level change and residents are beginning to evacuate the city. If it fully erupted, over 19 million residents would be affected. –The Christian Post - http://www.christianpost.com/news/popocatepetl-volcano-threatning-to-erupt-19-million-prepare-to-evacuate-73454/

    Santorini's underwater volcano activity resumes
    http://www.agi.it/english-version/world/elenco-notizie/201204172054-cro-ren1113-santorini_s_underwater_volcano_activity_resumes
    April 17, 2012 – GREECE – Santorini’s volcanic basin is showing signs of resumed volcanic activity. According to researchers at the Georgia Institute of Technology, satellite research tools suggest that a build-up of some 14m cubic meters of lava at a depth of 5km took place between September and January last. Widely touted by academics as the cause of the Minoan civilization’s obliteration, what is left of the volcano – a small archipelago – last witnessed significant geological activity in January of 2011. Having published his findings in the latest issue of Geophysical Research Letters, the Institute’s Andrew Newman says “our research shows that the lava build-up is accelerating,” suggesting that even though the build-up may not indicate an imminent eruption, it may cause minor volcanic events, including ash fall-out, landslides and even tsunami type phenomena. –AGI.it

    Mexican villages rocked by Popocatepetl volcano eruption
    April 21, 2012 – MEXICO - A 17,886ft volcano outside Mexico City has exhaled dozens of towering plumes of ash and shot fragments of glowing rock down its slopes, frightening the residents of surrounding villages with hours of low-pitched roaring not heard in a decade. A white cloud of ash, gas, water vapor and superheated rock spewed from the cone of Popocatepetl high above the village of Xalitzintla, whose residents said they were awakened by a window-rattling series of eruptions. Mexico’s National Disaster Prevention Centre said that a string of eruptions had ended in the early morning, then started up again at 5.05am, with at least 12 in two hours. “Up on the mountain, it feels incredible,” said Aaron Sanchez Ocelotl, 45, who was in his turf grass fields when the eruptions happened. “It sounds like the roaring of the sea.” The white cone of Popo, as most call the mountain, is an iconic backdrop to Mexico City’s skyline on clear days, but its 40-mile distance means even a moderately large eruption is unlikely to do more than dump ash on one of the world’s largest metropolitan areas. It is a different matter for the villages on the flanks of the volcano, where the quiet of the corn fields and fruit orchards was pervaded by the volcano’s spooky roaring. “Everyone needs to take this seriously. This buzzing, this roaring isn’t normal,” said Gregorio Fuentes Casquera, the assistant mayor of Xalitzintla, a village of 2,600 people about seven miles from the summit. He said the town had prepared 50 buses and was sending out its six-member police forces to alert people to be ready to evacuate. Dozens of women lined up in Xalitzintla’s main square to get free face masks and bottles of water. Health authorities were giving out 10 masks and 10 bottles of water to each family, and the surgical-style masks, intended to filter out the fine ash released by the volcano, were becoming common among the town’s students, who are required to wear them in school. Few adults wore them. President Felipe Calderon said live on national television that authorities are keeping open roads around the mountain, preparing emergency shelters and making sure residents know the latest information about a potential eruption. –The Press Association

    Colombia prepares for imminent eruption of Nevado del Ruiz volcano
    April 20, 2012 – COLOMBIA - Colombia’s government has called for high risk areas to be prepared for the eruption of the Nevado del Ruiz volcano. The Interior Ministry has ordered the fire departments of 19 municipalities in the central Caldas and Tolima departments to be on high alert after the Colombian Geological Survey (SGC) announced that an eruption is “probable” in the coming days or weeks. The alert level was raised from yellow to orange in March as the volcano became increasingly active. Last week a column of gas and steam approximately 1,200 meters tall extended from its crater. The national director of the firefighting system warned that there is urgent need for a special contingency plan that outlines tactics to be used in emergency volcanic situations, especially for search and rescue groups. He called for a focus on high risk areas in or near the paths of rivers that originate in the Ruiz, whose levels may be elevated by pyroclastic fragments and the melting of ice. The director of the Colombian Fire Department Federation in the town of Riosucio explained that local firemen are preparing a plan and educating communities. In 1985 The Nevado del Ruiz erupted, wiping out the town of Armero and killing 25,000 people. –Colombia Reports

    Ecuador’s Tungurahua volcano blows its top- raining down gravel in neaby town
    April 23, 2012 – ECUADOR – Over the weekend, the Tungurahua’s volcanic eruption had a strong explosion that caused gravel to fall down in the nearby town of Pillate, Ecuador. The explosion, characterized by its loud “cannon ball shot”, was immediately detected by locals and scientists observing the volcano’s progress. The explosion was later followed by a slight tremor and a constant pulsation of “high energy” said reports. The constant cloud coverage surrounding the volcano has caused scientists, from the Geophysical Institute branch of the National Polytechnic School to have trouble determining its current state. Most of the direct observations are conducted in the Guadalupe Observatory, the closest in the vicinity. Tungurahua, located in the Andes Mountains in Ecuador, is 5,016 meters high and its eruptions began in 1999. Since then, the volcano has transitioned from times of high activity and those of calm. However, Tungurahua is not the only volcano causing extreme damage and concern in the Hispanic world. Popocatépetl, located in Mexico City, has also been under close watch due to its recent activity which included ash blasts. -HSN

    Evacuation ordered at Indonesia’s Mt Lokon volcano in North Sulawesi
    April 24, 2012 – INDONESIA - Local residents around Mount Lokon in Tomohon, North Sulawesi, have been asked to evacuate the area, following a steady increase of activity in the mountain since 4 p.m. local time. “We are on alert status [Level 3],” said National Disaster Mitigation Agency (BNPB) spokesman Sutopo Purwo Nugroho on Monday. “We ask that local disaster mitigation agencies follow the technical recommendations we have given them. There should be no community activity within a 2.5 kilometer radius of the volcano crater,” Sutopo added. Mt. Lokon is located on the outskirts of Tomohon. It is 1,580 meters high and is located 20 kilometers west from Manado, North Sulawesi. According to the Volcanic and Geological Disaster Mitigation Center (PVMBG), Mt Lokon had previously erupted on June 14, 2011, sending ash and debris 1,500 meters into the sky. The next day, another eruption occurred that threw up volcanic material by 600 meters. Two residents died as a result of these eruptions. Other eruptions happened in 1991 and 2001, with the one in October 1991 causing Rp 1 billion (US$108 thousand) in damages, as well as the death of a Swiss tourist named Vivian Clavel. The 2001 eruption covered Manado in ashes and debris. The dust coming out of the mountain formed a 400 meter pillar. –Jakarta Post

    Lava from Puu Oo spreads over coastal plain
    AWESOME VIDEO: http://www.youtube.com/watch?feature=player_embedded&v=MM7b-JhMzJ0
    April 26, 2012 – HAWAII - Lava flows from Puu Oo vent are spreading over the coastal plain in Kalapana and over the weekend entered the Hawaii Volcanoes National Park. But the flows are still about a half-mile from the ocean. The Hawaiian Volcano Observatory released new lava photos taken Monday that show slow-moving breakouts of pahoehoe lava, with the characteristic look of bunched up rope as it cools. Other photos released in the last month show how the lava has been spreading on the plain, rather than moving directly to the south, toward the ocean. The plain is below the Pulama Pali and the Royal Gardens subdivision. The observatory also released video and thermal images showing the summit lava lake rising at Halemaumau Crater. A glow from the lava lake illuminates the gas plume coming from the vent at night. The lava level rises and falls as the volcano goes through inflation and deflation cycles. The lake level is about 230 feet below the floor of Halemaumau Crater. –Star Advertiser http://www.staradvertiser.com/news/breaking/148982355.html



    Santorini volcano showing signs of rapid inflation
    April 25, 2012 – GREECE – About 3600 years ago, at the height of Minoan civilization, Santorini let loose with one of the largest volcanic eruptions in history. The explosion blanketed nearby islands with piles of ash hundreds of feet thick and sent out a gigantic tsunami that devastated Crete, about 68 miles to the south. Smaller eruptions across the ensuing millennia ended abruptly in 1950. Then, after 60 years of calm, the caldera reawakened early last year with an escalating swarm of earthquakes. When geologists took a closer look, they could see the ground was swelling as well, as though the sleeping giant were yawning. The earthquakes and ground deformation scientists observed between 2011 and early 2012 are unprecedented since the 1950 eruption. But just because a volcano is sucking in breath doesn’t mean it will spew. Iceland’s Eyjafjallajökull stratovolcano really let loose in 2010 after its own swarm of deformation-driven tremors, but Long Valley caldera in California has been breathing heavily since 1980 with no eruption at all. In a recent analysis of the volcano published in Geophysical Research Letters, scientists estimate Santorini’s latest inflation is due to 14.1 million cubic meters of magma accumulating in a chamber about 4.5 kilometers below the surface. That may sound like a scary-big mass of melted rock, but it represents only about 0.03 percent of the estimated eruptive volume from the monstrous 1650 B.C. eruption—not nearly enough for a repeat performance. Should Santorini erupt, it will most likely be a relatively tame event, the study’s authors say. –Discovery

    Italy’s Mt. Etna erupts for seventh time in 2012
    April 24, 2012 – ITALY – Mt. Etna volcano erupted for the seventh – and without doubt the most spectacular – time this year today, spewing forth molten lava hundreds of meters into the air. Residents living close by were covered in hot ash but Europe’s tallest and most active volcano didn’t seem to pose any threat to human safety. Local inhabitants of the Sicilian town of Catania were grateful that Etna at least didn’t close the local airport as it did last month, preventing a visiting Serie A football team from leaving the island. The highest active volcano in Europe has blown its top three times in the past month alone, depositing a surface of black ash on its snowy higher slopes. Standing nearly 11,000ft high, Etna regularly. Tunnels and ditches have been dug to protect their villages from the lava flow. –Daily Mail http://www.dailymail.co.uk/sciencetech/article-2134501/Fingers-Etna-sends-stream-molten-lava-mountainside-erupting-seventh-time-year.html

    Time-bomb? Residents too afraid to sleep, ‘It’s making sounds we never heard before’
    April 24, 2012 – MEXICO – Residents at the foot of Mexico’s Popocatepetl volcano no longer sleep soundly since the towering mountain roared back into action over a week ago, spewing out a hail of rocks, steam and ash. “We close our eyes, but we don’t sleep much. In the past, there was only smoke but this time it’s stronger,” said Francisco Jimenez, who lives in the nearby town of Xalitzintla in central Mexico, 55km from Mexico City. The volcano, Mexico’s second highest peak at 5 452m, started rumbling and spurting high clouds of ash and steam on 13 April, provoking the authorities to raise the alert to level five on a seven-point scale. The alert extended a security cordon around the volcano but stopped short of starting evacuations of about 685 000 residents from nearby communities. Over the weekend, residents watched as Popocatepetl, which means “smoking mountain” in the indigenous Nahuatl language, lived up to its name, spouting glowing rocks and shaking the ground beneath their feet. “When we went out to see, my son cried: ‘We have to leave!’ We were ready to leave for Mexico City but then it calmed down a bit,” said 67-year-old Leopolda Perez of Xalitzintla. Authorities from the National Centre of Disaster Prevention maintained their alert level and said on Monday that the volcano remains at a “relative calm” state. After moderate activity during most of the 20th century, Popocatepetl registered more intense rumblings from 1994, with the strongest in December 2000, when nearby communities were evacuated. Juan Carlos Salazar, head of civil protection for the central state of Puebla, said that while many people thought lava was now coming out of the volcano, the crater was only spewing glowing rocks, with no risk to the population. Popocatepetl is an explosive volcano that can suddenly erupt at tremendous force, thrusting out rocks and ashes at large distances. That kind of volcano can be more dangerous than those releasing only flowing lava. Residents say they are used to the permanent threat of the volcano but many say the new activity makes them nervous again. “We’ve been watching out for many nights, waiting to see what happens,” said Gabino Santibanez, mayor of San Pedro Benito Juarez, a small town only 9km from the glowing crater. Locals said that most frightening was the unusual rumbling coming from the volcano, which many compared to an aircraft turbine. “We’ve never heard a noise like it,” said Maximiliano Grajales. About 4.5 million people live on the outskirts of the volcano, which lies at the crossroads of the states of Puebla, Morelos and Mexico. –News 24

    Nyamuragira volcano (DR Congo): new lava lake forming in summit crater?
    April 28, 2012 – AFRICA - Nyamuragira volcano in the DR Congo might be forming a new lava lake in its summit caldera. The volcano’s last eruption from the Kimanura fissure NE of the summit caldera seems to have ended by now. Until early to mid March, a lava lake was observed in the eastern vent and a strong heat source could be detected on satellite imagery, but has now disappeared. Seismic explosion signals from a source under the summit were noted on 24 February from the summit crater and overflights showed increased degassing from the central pit, which contained a lava lake until 1940. This activity increased in April and a strong SO2 odor from this area suggests the presence of near-surface magma. Scientists and the park rangers are speculating about the possibility that a new lava lake in the summit crater might be about to form. –Volcano Discovery http://www.volcanodiscovery.com/view_news/8322/Nyamuragira-volcano-DR-Congo-new-lava-lake-forming-in-summit-crater-.html




    Strong activity continues at Indonesia’s Mount Lokon volcano
    April 26, 2012 – REPUBLIKA.CO.ID, JAKARTA – Head of Data Center for Information and Public Relations of the National Disaster Management Agency (BNPB), Sutopo Purwo Nugrogo said Lokon was shaken by another volcanic tremor in Tomohon, North Sulawesi. In addition, the volcano is stirred by 1 to 3 shallow tremors every 5 minutes. If activity continues to increase at the volcano, officials fear an eruption could be imminent. The volcano remains at alert status 3 for now. The public is admonished to monitor the news for the latest updates about the volcano and a 2.5 kilometer exclusion zone remains in effect around the volcano’s parameter. –ROL




    Russia’s Shiveluch volcano ejects a 11 km ash cloud
    April 26, 2012 – RUSSIA -The Shiveluch volcano on Russia’s Far Eastern Kamchatka Peninsula on Thursday ejected an ash cloud to as high as nearly 11km above the sea level, the Itar-Tass news agency reported. An ash column from the volcano rose to a height of 10.7km above the sea level. There was no immediate threat for the population, and no emissions of volcanic dust were monitored in neighboring villages. Two earthquakes were registered at the volcano over the past 24 hours, which was given the highest Red Aviation Code. This was the most powerful eruption of ash registered at Shiveluch this year. Shiveluch has been active for more than four weeks. Shiveluch, standing 3,283 meters above the sea level, is Kamchatka’s northernmost active volcano. -DNA

    Slight increase in tremors and ash emissions at Ecuador’s Tungurahua volcano
    May 1, 2012 – ECUADOR - The Geophysical Institute of the National Polytechnic School today reported a slight increase in seismic activity and ash from the volcano Tungurahua. According to the Geophysical, from about 13:00 the seismic activity is characterized by the generation of a constant tremor signal, high frequency energy that remains. Also he could see a column of about 3 km emission with moderately high ash load and direction of movement to the west and south-west. Also reported minor ash falls in the sectors of El Manzano, Choglontús and Cahuají, south-west of the volcano, with almost constant roar of varying intensity. –La Hora


    Indonesia’s Mount Lokon volcano erupts again
    May 1, 2012 – INDONESIA – Mount Lokon volcano in North Sulawesi erupted again at 11:55 a.m. local time on Tuesday. The latest eruption was larger in magnitude compared to the eruption last Wednesday but local residents were more prepared. The eruption was preceded by a number of mild earthquakes over a span of two minutes. National Disaster Mitigation Agency (BNPB) spokesman Sutopo Purwo Nugroho said smoke plumes reached 2,500 meters in height when Mount Lokon erupted. According to geologists with the Volcanology and Geological Disaster Mitigation Center (PVMBG), it is not time for residents to evacuate yet, but evacuation sites are being prepared just in case. The BNPB has deployed a team to keep the situation in Mount Lokon under control. The agency has also prepared transport, Rp 400 million (US$43,600) in cash and other equipment. –Jakarta Post


    Indonesia’s Mount Merapi volcano entering preparation stage before an eruption
    May 1, 2012 – INDONESIA - The Mt. Merapi volcano restarted its inflation process immediately after the 2010 eruption and has entered its preparation stage of a forthcoming eruption, a Japanese researcher has said. Masako Iguchi, a researcher from the Disaster Prevention Research Institute at Kyoto University, said Tuesday that the global positioning system (GPS) installed on three Indonesian volcanoes, namely Guntur, Sinabung and Merapi, to detect their ground deformations, had signaled the inflation of Mt. Merapi. Before the 2010 eruption, he said, Merapi had erupted in 2001 and 2006. This showed that there were some periods in which the volcano had no deformation until it inflated and the next eruption occurred on Oct. 26, 2010. “But in this latest case, we detected that after its 2010 eruption, Merapi inflated again very quickly. This means that Merapi is a very active volcano,” Iguchi said during a meeting to present the team’s project report titled “Multi-Disciplinary Hazard Reduction from Earthquakes and Volcanoes in Indonesia.” The three-year project, which is funded by the Japan International Cooperation Agency (JICA) and the Japan Science and Technology (JST) institute, will end later this year. The project was led by Hery Harjono, an earthquake researcher from the Indonesian Institute of Sciences (LIPI). Iguchi said that during the observation, a joint team of experts from Indonesia and Japan found drastic changes in the chemistry of deposits around Merapi had occurred between October and November 2011. “More efforts are needed to develop eruption scenarios, volcano monitoring, and countermeasures to mitigate a possible volcanic disaster,” said Iguchi. Tomoyuki Tada, a JICA senior representative, said the “Multi-Disciplinary Hazard Reduction from Earthquakes and Volcanoes in Indonesia” project marked the first collaboration between the JICA and JST in Indonesia. “This is a very important project as Indonesia and Japan are both well-known countries for natural disasters,” he said. –Jakarta Globe

    Growing fears that North Korea’s infamous volcano will soon erupt
    May 3, 2012 – North Korea - There is growing concern about a possible eruption of Mt. Baekdu. The two Koreas remain at odds in everything. But they are one in voicing how to counter the possible volcanic explosion of the highest mountain in the Korean Peninsula. Inter-Korean anxiety is mounting, with growing apocalyptic predictions on the dormant volcano. A South Korean geological expert has warned that the volcano could erupt sometime around 2014 and 2015. Former North Korean leader Kim Jong-il reportedly said people in some regions of Yanggang and North Hamgyeong Provinces were feeling anxiety over a volcanic eruption of Mt. Baekdu. Kim called for quick countermeasures by the North Korean authorities. If a volcano, located on the border between North Korea and China erupts, damage could be 10 to 100 times greater than that caused by the April 2010 eruptions in Iceland. Experts predict that the ashes would not only hit the neighboring area but damage agriculture and cause serious disruptions in industrial activities and air flights. The Korean Peninsula, China, Japan and Russia would be severely damaged. A volcanic eruption begins when pressure on a magma chamber forces magma up through the conduit and out the volcano’s vents. When the magma chamber is completely filled, the type of eruption partly depends on the amount of gas and silica in the magma. The amount of silica determines how sticky (level of viscosity) the magma is and water provides the explosive potential of steam. Fears of a Mt. Baekdu eruption loom large with ensuing warnings based on a series of geological studies from experts. A growing number of scholars have not ruled out the possibility of another eruption, linking the collapse of Korea’s ancient kingdom, Balhae, with the previous one. One theory comes from Professor Hiroshi Machida of Tokyo Metropolitan University. Machida first presented a view in 1992 that the eruption of Mt. Baekdu (Mt. Changbai in Chinese) led to the fall of Balhae, which had expanded its sovereignty to the vast Manchuria territory. His theory was based on volcanic ash found in Tomakomai, a port city in southern Hokkaido, in 1981. The ash was named “Baekdu-Tomakomai volcanic ash” (B-Tm) after Mt. Baekdu and Tomakakomi city where it was found, according to So Won-ju who wrote the book “Secret of Mt. Baekdu’s Great Eruption.” Machida’s theory has gained momentum as an increasing number of geologists and climate change researchers have presented views that the ash was produced in the eruption of the highest mountain in the Korean Peninsula in the 10th century. The eruption of the 2,744 meter-high mountain was billed as the largest in the history of mankind and was about 50 times stronger than that of Mt. Vesuvius of Italy in 79 A.D. which led to the burying and destruction of the Roman city Pompeii. –Korean Times



    No. 53: Eruption of Pago volcano on-going in SW Britain, PNG
    May 3, 2012 – SW Britain, PAPUA NG – Pago is the post caldera volcanic cone of Witori which formed within the past 350 years. Mt Pago is a young volcano. Its cone is probably only about 350 years old, but it is part of a much larger volcanic complex, the Witori caldera, which formed 3300 years ago. Witori Caldera has long been recognized as active and is considered a potential dangerous volcano in the area. Since the Mt. Pago and Witori volcanoes are located in the same caldera, there is a possibility that an eruption of Mt. Pago may have similar effects on the Witori volcano. The volcano eruption is on-going and has gone from a red to an orange aviation alert advisory. The volcano had two VEI 6 events in its past history. -GDACS

    Volcanic debris from Popocatepetl volcano closes Mexico airport
    May 10, 2012 – MEXICO
    - Ashes from Mexico’s Popocatepetl volcano forced officials to close the airport in nearby Puebla for some 14 hours, to allow for cleanup after it spewed out heaps of ash and rock. The Puebla International Airport was able to reopen Wednesday after dozens of workers cleared its runways of volcanic ash that posed a risk to departing and arriving aircraft, said officials. The airport’s closing caused just one cancellation, a flight to Houston, Texas early Wednesday, said Puebla’s civil protection director Jesus Morales. Since Popocatepetl came to life several weeks ago, it has spewed gas and glowing rock as much as one mile (1.6 kilometers) beyond its crater, and has intermittently belched out water vapor and ash. Officials in this central Mexican state have prepared temporary shelters as a precaution and locals were wearing face masks to protect their lungs from ashes in a populous area around the volcano. The city of Puebla lies in the shadow of the volcano about 55 kilometers (35 miles) from the federal capital Mexico City. The country’s second highest peak, Popocatepetl, means ‘smoking mountain’ in the indigenous Nahuatl language. After moderate activity during most of the 20th century, the mountain registered intense rumblings beginning in 1994, with the strongest coming in December 2000, when nearby communities were evacuated. –Terra Daily

    High lava level reported at Kilauea volcano summit
    http://www.bigislandvideonews.com/2012/05/16/high-lava-level-reported-at-kilauea-volcano-summit/
    HAWAII VOLCANOES NATIONAL PARK, Hawaii: Scientists with the USGS Hawaiian Volcano Observatory are reporting a relatively high lava lake level at the Halema`uma`u crater vent over the past two days, following a summit inflation at Kilauea. The summit tiltmeter network recorded another DI deflation around 5 pm last night when the lava lake level started to drop; a laser rangefinder measurement yesterday placed the lava lake surface about 67 m (220 ft) below the Halema`uma`u Crater floor – a pretty high level. The lava has been close to the level of the deep inner ledge. A photo released by HVO (above) shows continuous spattering at the southern lake margin tossing spatter onto the crusted lake surface as well as onto the rim of the ledge, building a steep spatter rampart. HVO says the summit lava lake is deep within a 520 foot diameter cylindrical vent with nearly vertical sides inset within the east wall and floor of Halema`uma`u Crater. The lava level level fluctuates from about 200 feet to a level that puts it out of sight below the floor of Halema`uma`u Crater. The vent has been mostly active since opening with a small explosive event on March 19, 2008. Most recently, the lava level of the lake has remained below an inner ledge (200 ft below the floor of Halema`uma`u Crater on May 9, 2012) and responded to summit tilt changes with the lake receding during deflation and rising during inflation.

    Respiratory disease and infections increase due to Mexico’s volcanic activity

    May 17, 2012 – MEXICO - Acute respiratory infections increased by three percent among the inhabitants of the southeastern area of the State of Mexico, who are exposed to ash thrown by the Popocatepetl volcano, said the Ministry of Health. The head of the Department of Epidemiological Surveillance of the Mexico State Health Institute, Hector Resendiz, said the increase in these diseases has occurred in children under eight years old and adults over 60. According to the state agency, residents of Amecameca, Ozumba, Tepetlixpa, Ecatzingo and Atlautla are those who mostly received medical attention after April 21 when volcanic dust began to fall in those municipalities that are closest to Popocatépetl on the Mexico State’s side. Resendiz added that cases of conjunctivitis have also risen, “so far we have counted 348 cases of people who have been in contact with volcanic dust.” On Tuesday, the National Center for Disaster Prevention reported the new increased activity of the volcano, which now is on yellow alert phase three. –Prensa Latina

    Menacing terror: Mexico’s Popocatepetl spews fiery rock and ash, shakes buildings in nearby village
    May 18, 2012 – MEXICO – Fresh blasts from Mexico’s Popocatepetl volcano spewed fiery rock and caustic ash over residents around the Mexico City suburb of Puebla, already on edge after weeks of ongoing eruption. Ash soared 2.5 miles into the sky during early Saturday’s explosion, forcing a local airport to close. Residents of the nearby village of Santiago Xalitzintla rushed into the town square during the middle of the night as terrifying rumblings and blasts caused buildings to shudder. Last week residents in eastern parts of Mexico City were provided with face masks to protect them against ash raining over the region from Popocatepetl’s blasts. Prevailing winds have so far spared the capital district from significant ash falls. Popocatepetl has become increasingly active during 2012. A major eruption in 2000 forced 50,000 people to evacuate in three states that surround the towering mountain. –Earth Week

    Indonesia’s Mount Merapi volcano erupts again
    May 19, 2012 – INDONESIA – A report, published in the Journal of Volcanology and Geothermal Research, has unveiled recently that a volcano, namely Indonesia’s Mount Marapi, erupted early Friday at 7:15 a. m. local time, lasting for nearly ten minutes. It has been found that the volcano has had several such eruptions since when its alert status was updated last August. Also, the same has erupted for a total of around 454 times since the late eighteenth century till 2008. While a majority of these were minor eruptions, fifty of them were significant, last in the year 2005, found the team of researchers from Oregon State University. The erupted volcano is located in the province of West Sumatra, near the cities and town of Bukittinggi, Padang Panjang and Batusangkar in West Sumatra. As per the findings, the volcano is the most active one. It is being said that its eruptions had killed 300 people between October and November and had caused around 300,000 people to relocate as well. “Our study found some of the first evidence that the region has a much more explosive history than perhaps has been appreciated”, said Morgan Salisbury, lead author. –French Tribune



    Guatemala’s Fuego volcano emits massive ash cloud closing airport
    http://www.reuters.com/article/2012/05/19/guatemala-volcano-idUSL1E8GJ20420120519
    May 19, 2012 – GUATEMALA – Guatemala’s Fuego volcano belched burning lava and black ash into the sky early Saturday, leading the government to issue an airplane advisory and close section of highway. The volcano, about 25 miles (40 kilometers) southwest of the capital, erupted about 2:45 a.m. (0745 GMT), spewing a column of ash up to 16,400 feet (5,000 meters) above the crater and launching burning red lava nearly 1,300 feet (400 meters) high. The national emergency commission issued an advisory, warning plane not to fly within a 25-mile (40 kilometer) radius of the volcano. The La Aurora international airport in Guatemala City remained open. The commission also closed two stretches of highway threatened by lava flows that reached the base of the mountain. Guatemala’s four active volcanoes have a history of causing shut downs. In 2010, an explosion at the Pacaya volcano about 25 miles (40 kilometers) south of Guatemala City coated the city in a thick layer of black ash and rock, forcing hundreds of families to evacuate and closing the international airport. –Reuters

    Costa Rica’s Turrialba volcano alert status raised to yellow: authorities say an eruption could be imminent
    May 21, 2012 – COSTA RICA - Costa Rica’s National Seismological Network has upgraded the color threat level to yellow of Turrialba Volcano, in the province of Cartago east of the capital. A statement issued by Raúl Mora-Amador, coordinator of Seismology, Volcanology and Geophysical Exploration at the University of Costa Rica, indicates a threat level of yellow means that the National Seismological Network believes an eruption is “probable” in a matter of days, weeks or a few months. The upgrade in the threat level is due to “important changes in seismic activity of Volcano Turrialba associated with the movement of fluids, gas and magma beneath the surface, different from that observed in past years,” Mora-Amador’s statement says. Temperatures around some fumaroles on the volcano have risen to as much as 800° Celsius, accompanied by eruptions of ash. High-temperature emissions of volcanic gases including sulfur dioxide have increased, causing incandescence in some of the fumaroles, Mora-Amador said, adding that the internal wall of the active crater is very weak due to hydrothermal changes in the volcano. Mora-Amador indicated this could mean a major eruption could jettison material into the atmosphere. Turrialba is the only volcano in the country currently with a yellow threat-level indicator. An upgrade to red would mean an eruption is imminent. –Tico Times



    Japanese professor warns of high probability of eruption of Mt. Fuji within 3 years
    http://fukushima-diary.com/2012/05/high-possibility-of-mt-fujis-eruption/
    May 21, 2012 – JAPAN – Professor Emeritus, Kimura from Ryukyu University warns that an eruption of Mt. Fuji in 3 years is a bigger risk than previously thought possible earthquake because of the 34 km long fault found under the volcano. He points out these facts: One, from North east to South west of the crater, fumarole emissions are being observed. This is the water version of eruption instead of magma, but the mechanism is almost the same as normal eruption. In Fujinomiya city beside Mt. Fuji, water has been springing every few months since 2 years ago. Fujigoko Lake located at North to Mt. Fuji. And secondly, huge holes appear in the Fuji maneuvering ground of Japanese Self Defense Force. Natural gas is coming up from the holes. The temperature is 40℃ ~ 50℃. It is not the volcanic gas directly coming up from magma but considering water eruption as well, it is highly likely to be the omen of major eruption at the volcano. Mt. Fuji hasn’t erupted since 1707. According to the simulation of Cabinet Government, volcanic ash will be accumulated 2~10cm even in Tokyo, where is 100km away from Mt. Fuji. In the worst case, 14,600km of road will be closed. 515 flights will be cancelled a day. 1,080,000 houses will be out of power. The estimated economical damage will be 2 trillion and 500 billion yen. –Fukushima Diary



    Indonesia’s Mount Sirung volcano erupts, sending hundreds fleeing and complaining of respiratory ailments
    http://www.thejakartaglobe.com/home/ailments-spread-among-refugees-of-sirung-eruption/519153
    May 21, 2012 – INDONESIA – Mount Sirung’s eruption is causing a host of problems for Indonesia. Various ailments, including coughs and other respiratory conditions, have affected hundreds of people seeking safety in temporary shelters after the eruption of Mount Sirung on Pantar Island in the Eastern Nusa Tenggara District of Alor, an official said on Monday. Mount Sirung, an 862-meter-high volcano, erupted on May 13, forcing some 250 people from the Mauta village on its slope to seek safety elsewhere in the district. The volcano was put on the third level of alert after it began to show increased activity on May 8. “Residents are beginning to be affected by ailments such as coughs, sneezing, and other respiratory conditions,” Viktor Tanghana, the head of the Alor district Disaster Mitigation Office said. Viktor said children were the most vulnerable among the displaced. He said the district had already deployed a medical team to the temporary shelters to provide some help, and the authorities had also sent food aid such as rice, corn and instant noodles and cans of sardines. The evacuation of Mauta, approximately 300 meters from the crater, was conducted by the local authorities at the request of the Vulcanology and Geology Disaster Mitigation Center in Bandung (PVMBG), Viktor said. He said although the people of the village had been evacuated to the temporary shelters, they continued to return to their fields to work. Viktor also berated the shortage of face masks at the district level, and called on the disaster mitigation office in Kupang, the provincial capital to send at least 500 such masks to the district for distribution. –Jakarta Globe

    Alert level raised on Indonesia’s Soputan volcano after increased activity
    http://news.asiaone.com/News/AsiaOne%2BNews/Asia/Story/A1Story20120529-349069.html
    May 30. 2012 – INDONESIA – The Vulcanology and Geological Disaster Mitigation Center (PVMBG) has raised the alert status of Mt. Soputan in Minahasa and Southeast Minahasa regencies in North Sulawesi to level 3 — meaning “standby” — from the previous level 2 (alert), following increasing levels of volcanic activity. “Based on our observations, as of 3 p.m. on Monday, Mt. Soputan’s alert status was raised to level 3,” center head Surono said on Monday evening. According to Surono, increasing activity had been detected since May 25, when the volcano spew out white smoke to heights of between 50 meters and 75 meters above the mountain’s peak. The center has recorded dozens of different types of activity since then. The center’s highest alert status for volcanoes is level 4 (on guard). Surono has called on local residents to stay beyond a radius of six kilometers from the volcano’s summit. The center has also warned residents of the threat of a cold lava flood, urging people living near Ranowangko, Pentu, Lawian and Popang rivers to remain alert and aware. The volcano’s last eruption occurred on July 3, 2011. It erupted 10 hours after its status was raised to alert, forcing local officials to close Sam Ratulangi Airport for a day. –Asia One



    Massive ash cloud rises 7.3 km above Shiveluch volcano
    May 30. 2012 –KAMCHATKA – A volcano in Russia’s Far East Kamchatka spewed ash high into the sky on Tuesday following a series of tremors, local media reported. The column of ash from the 3.3-km-high Shiveluch volcano reached up to 7.3 km above sea level, according to the Itar-Tass news agency. No impact or damage has been reported vis-a-vis the powerful outburst, which came in the wake of a chain of seismic events around the region. Located on the Kamchatka peninsula, Shiveluch has been active since September 1980.



    Iceland’s Katla volcano shaken by swarm of 14 tremors

    May 30. 2012 – ICELAND - A swarm of 14 small to very small mostly very shallow quakes occurred at Katla volcano yesterday and today. Epicenter depths were reported between 0.1 and 12.2 km. Judging from the depth and magnitude of the quakes, the most likely cause for the seismic swarm are adjustments of the hydrothermal system under the icecap, and probably not magmatic intrusions (which would be possible indicators of a future new eruption). –Volcano Discovery



    40,000 displaced by war and violence in Democratic Republic of Congo
    http://allafrica.com/stories/201205291475.html
    May 30. 2012 – AFRICA – The latest outbreak of violence in the east of the Democratic Republic of the Congo (DRC) has displaced more than 40,000 people, the United Nations refugee agency said today, adding that the distribution of relief items will soon commence among those uprooted, with most of them having sought shelter in schools and churches. According to the Office of the UN High Commissioner for Refugee (UNHCR), most of the population displacement in the volatile North Kivu province is taking place in Rutshuru territory, north of the provincial capital, Goma. A UNHCR spokesperson, Melissa Fleming, told reporters in Geneva that the agency’s field staff reported fighting in Runyonyi, an area south of Rutshuru, on Saturday, between Government forces and renegade soldiers loyal to a former rebel commander, Bosco Ntaganda, who has been indicted by the International Criminal Court. The fighting continued until Sunday. UNHCR and aid agencies, including the UN World Food Program (WFP), the UN World Health Organization (WHO) and the International Committee of the Red Cross, will soon start distributing relief supplies, including food and medicines to the displaced. “Some of the displaced report cases of extortion, forced labor, forced recruitment of minors and beatings by armed men,” Ms. Fleming said in her press briefing. Refugees have also continued to cross the border into neighboring Rwanda, but in much smaller numbers, compared to the start of the crisis at the end of April. On average, between 150 and 200 people have been crossing the border daily. –All Africa



    Colombia's Ruiz Volcano Begins Rumbling; Nearby Airports Shut
    http://online.wsj.com/article/BT-CO-20120529-708571.html
    May 29. 2012 – COLOMBIA – Colombia warned Tuesday of a possible eruption of the Nevado del Ruiz volcano after it began rumbling and spewing gas, sending ashes onto cities and towns in the nearby coffee-growing region. The government’s geology and mining oversight institute Ingeominas said in a statement it raised the warning level to orange from yellow, which means an eruption is possible in days or weeks. The increased seismic activity began at around 3 a.m. local time (4 a.m. EDT). Civil aviation authority Aerocivil said operations have been suspended at the Manizales, Armenia, Cartago and Pereira airports, all in Colombia’s central-western coffee-growing region, due to visibility problems and concerns over aircraft engines getting clogged. This is the second time this year the warning level has been set at orange. It was raised to orange March 31, but brought back to yellow several days later as seismic activity declined. The 17,800-foot volcano, located west of Bogota, hasn’t erupted since the 1980s. An official at the Volcanology Observatory in Manizales, 16 miles northwest of the crater, said the city’s 360,000 residents have been able to see ash falling on the city since before dawn. In 1985, an eruption caused hot volcanic flows to melt the ice- and snow-covered summit area. This unleashed a cascade of debris down the volcano’s eastern slope, which wiped the town of Armero off the map, killing 25,000 people. Another 2,000 people were killed in nearby areas. -WSJ

    Guatemala’s Santiaguito and Fuego volcanoes rain down ash on nearby villages
    June 2, 2012 – GUATEMALA – Santiaguito volcano, (also known as Santa Maria) which has been in constant activity in recent days, erupted on Friday, ejecting columns of ash that reached 200 thousand meters high and covering much of the city of Quetzaltenango, the country’s east. This was reported by the local media on Friday, which quoted the National Institute of Seismology, Volcanology, Meteorology and Hydrology, stated that “Santiaguito volcano activity remains weak though with moderate explosions.” The institute’s report also said that in view of the wind shifts from south to north, favored the “fall of ash particles on the city of Quetzaltenango and its surroundings, causing some alarm. The ash fell on cars and roofs of houses and streets were light gray,” it said. Given the activity of the crater, the state National Coordinator for Disaster Reduction (Conrad) recommended that people “take necessary precautions to consider” whether to continue the activity of Santiaguito. This crater is located 206 km west of the capital and two thousand 500 meters high. Another active volcano in Guatemala is Fuego, the Fire, three thousand 763 meters high, which last week released ash on several nearby villages. Last week, the Conrad issued a warning orange-red pre-and recommended to the Directorate General of Civil Aviation to take precautions to air traffic. In turn, also asked to avoid flying near the fire, between the departments of Escuintla, Sacatepequez and Chimaltenango. –Telsurtv

    Scientists find new string of underwater volcanoes in New Zealand’s Bay of Plenty
    June 2, 2012 – NEW ZEALAND – A group of Wellington scientists have returned from an expedition confirming volcanic activity in a seamount or under-sea mountain off the Bay of Plenty. Niwa says the unique area needs protecting from activities like fishing and sea bed mining in the future. The Tangaroa seamount near White Island in the Bay of Plenty has been confirmed by a Niwa expedition to be volcanic. Niwa principal scientist Malcolm Clark says they have discovered new hydrothermal vents which create chimney-like structures. “Some of the venting we found was very high temperature, black smoker type situations, where the temperature is several hundred degrees Celsius.” The top of the seamount is nearly a kilometre below the ocean’s surface. “These are species which are adapted to live in quite extreme conditions, high levels of hydrogen sulphide which is toxic to most life forms, quite high temperatures, they’re deep, there’s no light, they’re under quite high pressure,” says Malcolm. Dr Clark has just returned from taking the first biological samples of the animals which have adapted to Tangaroa’s unique environmental conditions. There are 50 submarine volcanoes stretching along the Kermadec Ridge. It’s a significant feature of the Western Pacific, extending almost 1500km to the edge of the New Zealand., northeast of the Kermadec Islands. Hydrothermal vents associated with these volcanoes release hot water and gases with different chemical compositions, so specific communities have adapted to survive in each area. –Sun Live

    Mexico’s Popocatepetl volcano unleashes tower of ash
    June 1. 2012 – MEXICO – Mexico’s Popocatepetl Volcano has blasted a tower of ash over nearby towns and villages prompting authorities to consider the possibility of evacuations. Popocatepetl sits roughly halfway between Mexico City and the city of Puebla, meaning some 25 million people live within a 90-km (60-mile) radius of the volcano. Over a month ago, the volcanic eruptions started growing larger. –BBC

    500 evacuated from vicinity of Colombia’s Nevado del Ruiz volcano
    May 31. 2012 – COLOMBIA – A light spewing of ash amid renewed rumblings in the Nevado del Ruiz volcano prompted Colombian authorities to evacuate 500 people from beneath its flanks and briefly suspend flights at four airports. The volcano’s seismic activity was more intense than episodes in April and early May, when it emitted columns of steam, said the government geological agency Ingeominas. The 17,160ft volcano spouted ash that fell on population centers including the western city of Manizales. –Herald

    Growing unrest: preventive alert declared for three Costa Rican volcanoes
    May 31. 2012 – COSTA RICA – The National Emergency Commission (CNE) on Wednesday declared a preventive “green alert” due to recent seismic activity at three volcanoes: Rincón de la Vieja, in the northwestern province of Guanacaste, Poás, northwest of San José in the province of Alajuela, and Turrialba, in the eastern province of Cartago. “The CNE’s alert is supported by reports from technical and scientific agencies that note the volcanoes are in constant activity,” the commission stated. Turrialba Volcano, 70 kilometers east of the capital, has seen significant volcanic and seismic activity in recent months, prompting the National Seismological Network to upgraded its own color threat level to yellow. Emissions of gas at Poás Volcano are expected to increase, and Rincón de la Vieja Volcano has also seen significant volcanic activity, the CNE noted. Despite the warning, access to the volcanoes will remain open to the public, but visitors must follow guidelines issued at each national park’s entrance. –Tico Times

    Super-volcanoes can form and erupt in hundreds of years, not thousands says new findings
    May 31. 2012 – YELLOWSTONE – The largest volcanoes on our planet may take as little as a few hundred years to form and erupt. These “super-volcanoes” were thought to exist for as much as 200,000 years before releasing their vast underground pools of molten rock. Researchers reporting in Plos One have sampled the rock at the super-volcano site of Long Valley in California. Their findings suggest that the magma pool beneath it erupted within as little as hundreds of years of forming. That eruption is estimated to have happened about 760,000 years ago, and would have covered half of North America in its ash. Such super-eruptions can release thousands of cubic kilometers of debris – hundreds of times larger than any eruption seen in the history of humanity. Eruptions on this scale could release enough ash to influence the global weather for years, and one theory holds that the Lake Toba eruption in Indonesia about 70,000 years ago had long-term effects that nearly wiped out humans altogether. What little is known about the formation of these super-volcanoes is largely based on the study of crystals of a material called zircon, which contains small amounts of radioactive elements whose age can be estimated using the same techniques used to date archaeological artifacts and dinosaur bones. Because the processes and timescales of quartz formation in the extraordinary underground conditions of a magma pool are well-known, the team was able to determine how long the crystals were forming within Long Valley’s super-volcano before being spewed out in the eruption. Their estimates suggest the quartz formed over a range of time between 500 and 3,000 years. “Our study suggests that when these exceptionally large magma pools form they are ephemeral and cannot exist very long without erupting,’ said Dr Gualda. “The fact that the process of magma body formation occurs in historical time, instead of geological time, completely changes the nature of the problem.” At present, geologists do not believe that any of Earth’s known giant magma pools are in imminent danger of eruption, but the results suggest future work to better understand how the pools develop, and aim ultimately to predict devastating super-eruptions. –BBC

    Shiveluch volcano on Kamchatka spews ash 8 km high
    http://english.ruvr.ru/2012_06_15/78185174/
    June 15, 2012 – KAMCHATKA - The Shiveluch volcano on Kamchatka Peninsula in Russia’s Far East has erupted with ash rising to an altitude of 8 km above sea level, ITAR-TASS reports. Currently there is no danger for local communities. The eruption was accompanied by underground shocks which lasted 3.5 minutes. The Shiveluch volcano is the most northern and the most active volcano on Kamchatka. The volcano became active in 1980. –Voice of Russia
