    December 27, 2011 – JAKARTA — One of Indonesia’s most active volcanoes erupted Tuesday, spewing clouds of ash and panicking villagers but no evacuation has been ordered so far, a government vulcanologist said. The first eruption at Mount Lokon was at 3:07 am (1907 GMT Monday), followed by two more bursts within minutes, Farid Bina told AFP from a monitoring post near the volcano on Sulawesi island. “The eruption was heard as far as five kilometers (three miles) away, causing panic among villagers living close to the volcano,” he said, adding that winds blew volcanic ash to villages up to five kilometers to the east and northeast. “Two villages with about 10,000 people each have been affected by the ash, which stopped later in the morning,” he added. More than 5,200 people were evacuated to temporary shelters when the 1,580-metre volcano erupted in July, sending huge clouds of ash as high as 3,500 meters (11,500 feet) into the sky. Lokon’s last deadly eruption was in 1991, killing a Swiss tourist. The Indonesian archipelago has dozens of active volcanoes and straddles major tectonic fault lines known as the “Ring of Fire” between the Pacific and Indian oceans. The country’s most active volcano, Mount Merapi in central Java, killed more than 350 people in a series of violent eruptions last year. -AFP

    Deadly cold lava mudflows down slopes of Indonesia’s Mt. Gamalama volcano kills 4
    December 28, 2011 – INDONESIA – Officials say fast-moving mudflows streaming from the mouth of a volcano in eastern Indonesia have killed four villagers. About 1,000 others have fled their homes. Mount Gamalama, located in the Molucca Islands, sprang back to life this month with a powerful, non-fatal eruption. Government spokesman Yusuf Sunnya said Wednesday that days of heavy rains triggered flows of cold lava, rocks and other debris that slammed into villages near the base Tuesday night. He said four people were killed and more than a dozen others were hospitalized with injuries ranging from broken bones to head wounds. Indonesia is a vast archipelago with millions of people living on mountains or near fertile flood plains. Seasonal downpours here often cause landslides. –Time


    Quattro persone sono morte e mille hanno dovuto lasciare le loro case a causa di colate di lava fredda e fango fuoriuscite dalla bocca del vulcano Gamalama, nelle Molucche, nell'Indonesia orientale. Il vulcano è tornato in attività a dicembre con una potente eruzione. Il portavoce del governo indonesiano, Yusuf Sunnya ha fatto sapere che piogge intense hanno provocato le colate di lava fredda, rocce e fango che hanno colpito villaggi situati alla base del Gamalama. Una dozzina di persone è stata ricoverata con fratture e lesioni alla testa.

    Surtseyan eruption along the coast of Yemen forms a new island – Today eruption cloud + stain

    Jorgen Aabech, a Norvegian volcano enthusiast writing already a long time in his blog vulkaner.no, wrote us an email on December 20 to attract our attention on a probably new eruption of the Jebel Zubair volcano, which is an island formation on the territory of Yemen. Jorgen asked us if we had any mention of earthquakes in the area, which was negative.

    When looking at the Modis Terra and Aqua satellite picture on December 20, we saw indeed a very small cloud in the island area, but nothing important to us. We also followed the Sat24 weather satellite pictures for a while to eventually detect heat on their Infrared images, but also this was negative. This whole eruption, actually found by the scanning of Jorgen Aalbach (if we are right), was almost forgotten until NASA’s Earth Observatory published a far better satellite picture showing more detail of the eruption. Just like during the Eritrea Nabro eruption, satellite images are the only source in this part of the world (in other words, these countries have other concerns than following an active volcano area all the time).

    Increased seismic activity of Santorini volcano in 2011/2012:
    Seismic swarm at Santorini volcano, Greece
    Seismic swarm at Santorini volcano 1-2 Jan 2012 (source: Department of Geophysics, Aristoteles University of Thessaloniki) The seismic unrest beneath Santorini which had started in July 2011 continues into 2012, greeting the world with a small swarm of quakes beneath the caldera. The slightly increased number of quakes is concentrated on the volcano-tectonic Kameni line, which stretches SW-NE through the caldera and extends outside, especially to the NE where the submarine volcano Kolumbo is located 8 km off the coast. The alignment defines a tectonic graben structure underlying Santorini and has been used for rising magma for nearly all past eruptions of the volcano.

    * It's similar in size to Mount Pinatubo, which in 1991 gave us the biggest eruption of the 20th century
    * Billions of tons of ash and magma would be ejected
    * Southern England would be covered in ash

    January 2, 2012 – GERMANY – A sleeping super-volcano in Germany is showing worrying signs of waking up. It’s lurking just 390 miles away underneath the tranquil Laacher See Lake near Bonn and is capable of ejecting billions of tons of magma. This monster erupts every 10 to 12,000 years and last went off 12,900 years ago, so it could blow at any time. The Laacher See volcano is similar in size to Mount Pinatubo, which caused a 0.5C drop in global temperatures when it erupted in 1991. It covered 620 square miles of land with ash and rocks and several small earthquakes in the region last year indicate that it could be awakening from its deep sleep. Experts believe that if it did go off, it could lead to widespread devastation, mass evacuations and even short-term global cooling from the resulting ash cloud blocking the Sun. The effect on the UK is hard to predict but it’s possible that large parts of southern England could be covered ash. It’s thought that the volcano is similar in size and power to Mount Pinatubo in the Philippines, which blew in 1991 and became the biggest eruption of the 20th century. It ejected 10 billion tons of magma, 20 billion tons of sulphur dioxide 16 cubic kilometres of ash and caused a 0.5C drop in global temperatures. Volcanologists believe that the Laacher See volcano is still active as carbon dioxide is bubbling up to the lake’s surface, which indicates that the magma chamber below is ‘degassing.’ –Daily Mail

    http://www.earthtimes.org/pollution/mercury-caused-mass-extinctions-scientists/1744/
    New study suggests mercury from firestorm of volcanic eruptions caused past extinction
    January 7, 2012 – EARTH – Mass extinctions during catastrophic climate change were caused by huge mercury levels, Canadian scientists say. The Earth’s greatest global loss of life, around 250 million years ago, wiped out almost all marine creatures and most land-dwellers. Now, researchers at the University of Calgary have published a paper in the Geology journal, which blames massive mercury levels from volcanic eruptions, 30 times greater than those seen today. Co-author, Dr. Steve Grasby, an adjunct professor at the University of Calgary and a research scientist at Natural Resources Canada, says, “No one had ever looked to see if mercury was a potential culprit. This was a time of the greatest volcanic activity in Earth’s history and we know today that the largest source of mercury comes from volcanic eruptions. We estimate that the mercury released then could have been up to 30 times greater than today’s volcanic activity, making the event truly catastrophic.” This is the first study to blame mercury for the Permian extinctions, says co-author and University of Calgary Geology Professor, Dr. Benoit Beauchamp. “Geologists, including myself should be taking notes and taking another look at the other five big extinction events.” The loss of marine life occurred after the oceans were contaminated by the mercury, explains Dr. Hamed Sanei, adjunct professor at the University of Calgary and research scientist at Natural Resources Canada. “Typically, algae acts like a scavenger and buries the mercury in the sediment, mitigating the effect in the oceans. But in this case, the load was just so huge that it could not stop the damage.” In the Permian period, the land was a single continent. It is commonly thought that the eruptions from the volcanoes released carbon dioxide and other deadly poisons after penetrating coal seams. The Calgary University team provided evidence for this in a paper previously published in the Nature Geoscience journal. –Earth Times

    Magma Plume: Renewed activity at Canary Islands, El Hierro volcano
    January 6, 2012 CANARY ISLANDS – Looks like 2012 is trying to start out busy – we got an impressive eruption of Etna the other day and now it seems that El Hierro is showing renewed vigor. (Below) New video from INVOLCAN and images from the webcams show that the sea surface is steaming and reports from people at El Hierro say that new pyroclastic chunks (the “coconuts”) have been spotted as well. Diario El Hierro is reporting an increase in seismic tremor at the volcano over the last 24 hours. Not much is showing on the El Hierro webcams, but it’s never a bad idea to keep an eye on them. You never know if the activity might continue long enough to produce a subaerial eruption (such as the activity at Jebel Zubair in the Red Sea), but right now, we’re still likely a long way from that. –Wired

    http://www.wired.com/wiredscience/2012/01/elevated-alert-status-at-chiles-lascar/
    Raised alert status: 300 tremors reported over 26 hour period at Chile’s Lascar volcano
    January 6, 2012 – CHILE – Lascar, one of the more active volcanoes of northern Chile, was placed on heightened alert status by the ONEMI (Chilean Emergency Management) on advice from the SERNAGEOMIN (Chilean Geologic Survey). The latest report from Lascar says that over 300 small earthquakes have occurred at the volcano in the last 26 hours, leading to an elevation of its status to Yellow – however, there have been no indications of increased fumarolic activity at the volcano. Lascar has the potential to produce a large eruptive column – the 1993 eruption sent ash as fall east as Buenos Aires – with pyroclastic flows that could reach nearby towns such as Talabre. The volcano has been through a number of cycles of significant explosive activity over its 43,000 year history. However, recent activity is mostly lava dome formation in the summit crater followed by crater collapse and vulcanian to plinian explosive eruptions such as the major eruption of April 1993. However, it also have the potential to produce small explosions that will only dust ash on the countryside surrounding the volcano as it has done at least 6 times in the last decade. ONEMI is preparing for possible evacuations for people near the volcano – mostly either miners in the area or tourists at San Pedro de Atacama. If anything does occur, there is a webcam pointed at Lascar to see the action.

    In other news from Chile, it appears that the activity at Callaqui might have been merely very vigorous fumaroles rather than ash. The news in this week’s GVP Weekly Volcanic Activity Report mentioned a pilot seeing an “ash plume” from Callaqui, but the SERNAGEOMIN said they have seen no change in the seismicity (or lack thereof) at Callaqui. OVDAS (the volcano monitoring arm of the SERNAGEOMIN) mentioned that fumaroles are common at Callaqui, especially in certain weather conditions. –Wired

    Hundreds evacuate as activity rises at Indonesia’s Mount Lewotolok volcano
    January 6, 2012 – Kupang, INDONESIA – Hundreds of people living near a volcano in the Indonesian province of East Nusa Tenggara were evacuated on Thursday because of increased volcanic activity, the Antara news agency reported. About 500 people residing near Mount Lewotolok in Lembata district abandoned their homes amid the volcano’s mounting activity. “Most of them left for the nearest city, Lewoleba,” said Lembata Deputy District Chief Viktor Mado Watun, as quoted by Antara. “All related government officials will soon hold a coordination meeting to deal with the latest situation. Black smoke columns are coming out of the mountain’s crater, the air is filled with the smell of sulfur while rumbling sounds are heard around the mountain,” he added. Residents decided to leave due to the increasing activity of Mount Lewotolok over the past few days, even though the government has not yet announced an evacuation plan. Viktor said ten villages are likely to be affected and suffer material losses if the volcano erupts. On January 2, the country’s Volcanology and Geology Disaster Mitigation Center (PVMBG) raised the alert level at the volcano to level 3. The center uses a warning system with four levels of alerts, with level 1 being the lowest and level 4 being the highest. Dozens of active volcanoes in Indonesia are part of the Pacific Ring of Fire, known for frequent earthquakes and volcanic eruptions. One of Indonesia’s most active volcanoes is Mount Merapi, which is located on the island of Java near Jogjakarta, the country’s second-most visited area after Bali. In 2010, more than 300 people were killed in a series of eruptions between October and November which also displaced over 300,000 people. –Channel 6 News

    Activity increases as Nicaragua’s Masaya volcano
    January 10, 2012 – NICARAGUA – There is no incandescence currently as part of the wall near the vent collapsed into it. Local people are expecting an eruption to clear it. One can hear churning and avalanches and there is quite a bit of gas; you better put the mask on or you can only stay 10-15 min on lookout. The dormant crater next door looks like has a small lava dome in it which is slowly rising. The trees and plants don’t grow properly maybe because of CO2 in this crater? –Volcano Discovery http://www.volcanodiscovery.com/view_news/4266/Masaya-volcano-Nicaragua-activity-update-strong-degassing-no-visible-glow-inside-crater.html

    Restless large caldera: Masaya is a shield volcano located 20 km south of Managua, Nicaragua. It is Nicaragua’s first and largest National Park, and one of 78 protected areas of Nicaragua. The volcanic complex is composed of a nested set of calderas and craters, the largest of which is Las Sierras shield volcano and caldera. Within this caldera lies Masaya Volcano sensu stricto, a shallow shield volcano composed of basaltic lavas and tephras. This hosts Masaya caldera, formed 2500 years ago by an 8-km³ basaltic ignimbrite eruption. Inside this caldera a new basaltic complex has grown from eruptions mainly on a semi-circular set of vents that include the Masaya and Nindiri cones. Although the recent activity of Masaya has largely been dominated by continuous degassing from an occasionally lava-filled pit crater, a number of discrete explosive events have occurred in the last 50 years. Masaya’s last eruption occurred in 2008. –Wikipedia

    Arizona 3.1 magnitude tremor strikes between state’s dormant volcanoes
    January 9, 2012 – WINSLOW, Ariz. — The U.S. Geological Survey recorded a magnitude 3.1 earthquake in Arizona Sunday afternoon. According to the USGS, the quake hit at 12:11 p.m. about 21 miles southwest of Winslow and about 113 miles northeast of Phoenix. Winslow is about a 3-hour drive from Phoenix. With a depth of just over 3 miles, the temblor was a relatively shallow one. Google Earth shows the epicenter to be between what appear to be small dormant volcanoes. The volcano to the south of the epicenter is on the Colorado Plateau between the Mogollon Rim and Winslow. The remnants of the two cones to the north appeared to have been weathered away, leaving a plateau behind. Google Earth also showed a sinkhole swarm not far from the epicenter. Meteor Crater, one of the best-known meteorite impact craters on the planet, is 20 miles west of Winslow, putting it in the circumference of the quake. USGS data indicates that pockets of residents in the Payson and Prescott areas might have felt the quake, but it would have been very weak. Chances are if it was felt at all, it was simply a subtle, gentle shake that people might have noticed unless they were still or sitting down. –AZ Family

    Costa Rica: "Yellow" Alert For Turrialba Volcano Eruption
    January 13, 2012 – COSTA RICA – The emanation of a gray cloud, possibly containing ash, at the Turrialba Volcano was confirmed Thursday afternoon by the Observatorio Vulcanológico y Sismológico de CostaRica (OVSICORI), that resulting in the closure of the park. The eruption of smoke was confirmed at 3pm Thursday, preceded by rumblings that were detected by locals and confirmed by the OSVICORI. Almost immediately the Comisión Nacional de Emergencias (CNE) – national Emergency Commission – issued a “yellow” alert for the area as a preventive measure. The alert takes in the areas of Turrialba, Jiménez and Alvarado. For the areas Oreamuno and Cartago, the alert is at “green,” according to Vanessa Rosales, president of the CNE. Experts will be meeting today to discuss the risk and review technical reports to determine possible preventive measures. –Inside Costa Rica

    January 15, 2011 – INDONESIA – Padang, West Sumatra. Twenty-five volcanoes in Indonesia are now showing abnormal activity or have been put on alert or watch status, presidential special aide Andi Arief said here on Saturday. “According to official data, 25 volcanoes are now under alert or watch status and they must be given priority with regard to disaster mitigation planning at district or city levels,” he said at a workshop on journalists’ role in disaster management. He said in West Sumatra there were two volcanoes that need to be closely watched, namely Mount Marapi and Mount Talang, as they are still under alert status. Mount Marapi is located in Agam and Tanahdatar districts and rises 2891 meters above sea level, and Mount Talang (2597 meters above sea level) in Solok district was located around 40 kilometers from the provincial capital Padang. Apart from the two volcanoes, the government and regional disaster management agencies were also giving priority attention to Mount Papandayan in West Java, Mount Karangetan and Lokon in North Sulawesi, Mount Ijen in East Java, Mount Gamalama in North Maluku, Mount Krakatau in Banten and Lampung and Mount Lewoloto in East Nusa Tenggara. He said “it is not impossible that volcanoes that are now still normal could change to become abnormal due to earthquakes that have happened to trigger magma in the mountains to increase their activity, and therefore alertness and readiness of the people must continue to be maintained.” Andi said earthquakes below five on the Richter Scale could trigger magma in the volcanoes to rise and so people must not only be alert over big but also small tremors. The 4.4 magnitude earthquake like the one in Singkawang, West Kalimantan, is one of the examples, where people had never predicted before that it could happen there, he said. “The small magnitude quake is now being studied by researchers with regard to minimizing the damage in case an eruption happens in the country as there are a lot of volcanoes in Indonesia,” he said. –Jakarta Globe

    Increased activity at volcanoes in Guatemala
    January 20, 2012 – GUATEMALA - Fuego volcano produced explosions observed on 11-13 and on 16 January, which produced ash plumes rising 400-1000 m above the crater. Shock waves and rumbling sounds accompanied the explosions and rattled windows and roofs in nearby villages. Rock avalanches traveled SW into the Ceniza drainage and on the W, S, and SW flanks.

Sporadic explosions produce ash clouds that rise up to 600-800 m above the lava dome and mostly drift SW. A viscous lava flow is active on the SE flank. Block avalanches are generated from the front of the lava flow and on the SW flank, accompanied by rumbling noises. –Volcano Discovery

    January 27, 2012 – ECUADOR - Since Monday 23 January 2012, there has been an intensification of Sangay volcano’s activity, as indicated by reports from pilots who reported the presence of ash from the volcano drifting S-SE. In addition, satellite images from 24 Jan show the presence of thermal anomalies at the volcano. Sangay is one of the most active volcanoes in Ecuador, in frequent activity since the 17th century when it was discovered. However, due to its very remote location, at the eastern end of the Andes cordillera, its monitoring is limited to occasional field observations and observations by aircraft and from satellite. –Volcano Discovery

    Mexico’s turbulent Popocatépetl volcano erupts again
    January 27, 2012 – MEXICO - The 5,400-metre high Popocatepeti volcano has erupted again with a plume of ash after shaking for several minutes early on Thursday. Civil protection authorities reported that the cloud drifted west before turning back eat towards Puebla City. Lying 37 miles southeast of Mexico City and its 18 million inhabitants it remains to be seen how the ash cloud will effect the megalopolis. The volcano’s activity has been reported as stable and there is no threat to populated areas. However, authorities have urged people to stay at least seven miles from the area and to await further information from Mexico’s national disaster prevention agency. The gas cloud is the largest in many years with authorities eagerly keeping watch over any potential change in activity. Popocatepetl has had more than 15 major eruptions since the arrival of the Spanish in 1519. –India TV




    Costa Rica’s Turrialba volcano unleashes 15,000 ft ash cloud
    http://www.earthweek.com/2012/ew120127/ew120127d.html
    January 27, 2012 – COSTA RICA – Costa Rica’s Turrialba volcano produced a burst of activity that shot water, vapor and ash more than 15,000 feet into the air. Nearby residents reported that ash from the blast showered several communities. The mountain’s volcano observatory said that a new fissure broke open on the southeastern flank of the crater during the eruption. Turrialba last produced an eruption in 1866, which sent ash falling as far away as Nicaragua, according to historical records. The mountain has become increasingly active since it began to rumble again in January 2001. In January 2010, it spewed ash with such force that two nearby villages, La Central and El Retiro, were evacuated briefly. –Earth Week

    Sea temperatures around El Hierro much higher than normal – CO2 emissions SEVEN TIMES greater than normal. “With the underwater volcanic eruption in el Hierro continuing I keep a daily eye on its activities,” says reader Hans Schreuder. “I spotted this latest update on the dedicated Canarias 7 newspaper page.” “According to the article, the difference in surface sea temperature around the underwater eruption is now 4.9°C higher than normal, as measured on January 7 this year, and higher than in December last year, when it was 3.0°C higher,” says Hans.

    “It also states that the emission of carbon dioxide has reached 2.398 ± 115 tonnes per day, some seven times greater than normal. Other reports by the same authority stated that the emissions reached 1,665 tonnes a day so there are large variations.”

    “This little volcano proves once again that carbon dioxide comes from within the earth and enters the atmosphere via the oceans and that the seas are warmed from below by the uncounted eruptions and black smokers.” (Italics added.)

    “For the alarmists to claim that atmospheric carbon dioxide enters the oceans and causes “acidification” is plain nonsense and untrue.”

    Ok this is just an idea. But here is a link to El hiero on google maps. When you zoom in it appears that someone has done a bit of creative photoshopping on the image. The west end side is blured over. That could be me not understanding something, then agzin I could have it right.
    http://maps.google.fr/maps?q=El+Hierro,+Santa-Cruz+de+T%C3%A9n%C3%A9rife,+Iles+Canaries,+Espagne&hl=fr&ie=UTF8&ll=27.859718,-18.005219&spn=0.369698,0.617294&geocode=FbsOpwEdk_js_g&hnear=El+Hierro&t=h&z=11

    The other thing is that now they have put a real spanner in the gulf stream loop with their games in the Gulf of Mexico. There is 2 ways in which this could go. The dead sea bed or covered sea bed in the G.o.M could heat up trememdously fast because of this. Also Hiero Volcano is opposite the G.o.M If the planet was going into a flip then the motor of the sea currents would also have to change. Ideally before the flip. May be El Hiero is this in action?

    Just a thought.

    Alert level raised at Alaska’s Celevland Volcano – explosions expected with lava dome
    http://www.sacbee.com/2012/01/31/4229154/alaska-volcano-lava-dome-forms.html
    February 1, 2012 – ANCHORAGE, Alaska — The warning level for a remote Alaska volcano has been raised after a new lava dome began forming, indicating the mountain could explode and send up an ash cloud that could threaten aircraft. The Alaska Volcano Observatory on Tuesday elevated the alert status for Cleveland Volcano. Officials say the new lava dome was spotted in the summit crater. The observatory says as of Monday, the dome was about 130 feet in diameter. There have been no eruptions since Dec. 25 and Dec. 29, which destroyed the earlier lava dome built up over the fall. Cleveland is a 5,675-foot peak on an uninhabited island 940 miles southwest of Anchorage. Authorities say sudden eruptions could occur at any time, and ash clouds 20,000 feet above sea level are possible. –Sac Bee

    February 6, 2012 – INDONESIA - A slight increase in activity of Semeru volcano’s activity has been observed by the Indonesian Geological Survey in recent weeks and its alert level was raised to 3 (out of 4, watch) on 3 February 2012, after it had been on level 2 since 16 July 2009. Only small to moderate eruptions had been occurring over most of the past year. Between 29 December and 15 January, 8 explosions were counted which produced ash clouds up to 600 m high. One explosion threw incandescent bombs to a distance of 300 m from the Jonggring Seloko crater. During 15-29 January, only weak explosions were recorded and a small steam and ash plume rising 25-50 m was observed. Between 30 and 31 January, 5 explosions were recorded. They produced incandescent fallout in up to 400 m distance. On 2 February at 07:47 local time, a stronger explosion produced incandescent bombs that reached 750 m distance and caused a small avalanche of blocks rolling down a distance of up to 2.5 km. The heightened activity triggered the raise in alert level the following day. At its present status level of 3, PVMBG recommends to stay away at least 4 km from the summit on the SE side of the volcano and climbers are advised not to approach the Jonggring Seloko crater less than 1 km. As of 6 February, no significant changes to its activity have been reported by our correspondent on location. –Volcano Discovery

    Philippines Mt. Kanlaon volcano summit closed after large cracks found near crater
    February 10, 2012 – BACOLOD CITY, Philippines – Mount Kanlaon, an active volcano, has been declared temporarily closed to mountaineers after large cracks believed to have been caused by Monday’s 6.9-magnitude earthquake were observed at its crater and land surfaces, a local official said Friday. Kanlaon straddles the provinces of Negros Occidental and Negros Oriental. It has an elevation of 2,435 meters (7,989 feet) and a base diameter of 30 kilometers. Cecil Cañada, Mt. Kanlaon Natural Park (MKNP) superintendent, said at least three 50-meter long cracks have been noted near the crater, while other cracks and a landslide have been noted within the MKNP. A landslide was also seen at the Margaha Valley, the old crater of the volcano, he added. An assessment was conducted by accredited trained guides and members of the rescue group based in Guintubdan, La Carlota City, in coordination with the MKNP Eco-tourism Officer and Biologist Angelo Bibar, Cañada said. Their report revealed that some portions of the volcano’s crater were affected, and land surfaces had cracks and evidences of landslides, he said. Cañada also maintained that the aftershocks from Monday’s earthquake and occasional heavy rainfall could pose danger to the life of mountain trekkers and tourists in the park. The Philippine Institute of Volcanology and Seismology has been informed of the quake damage to the volcano and they were trying to arrange for an aerial survey of the area, he added. However, it is difficult to get a helicopter as they are being used for relief operations in Negros Oriental, Cañada said. The volcano continues to be under observation amid the continuing aftershocks, he said. The Mt. Kanlaon volcano is part of the Negros volcanic belt and last erupted in 2006. –Inquirer



    Indonesia’s Mt. Lokon volcano unleashes 2 km high ash cloud
    February 10, 2012 – INDONESIA – A restless volcano in northern Indonesia erupted Friday, spewing clouds of ash as high as 2 kilometers into the sky, the country’s National Disaster Management Agency said. The authorities are warning residents to stay away from the volcano, Mt. Lokon, in North Sulawesi, said Sutopo Purwo Nugroho, a spokesman for the disaster management agency. A 2.5 kilometer exclusion zone had already been set up around Mt. Lokon, which had been showing signs of activity in recent days. A series of eruptions by Mt. Lokon in July prompted the evacuation of thousands of local residents. The volcano also erupted in October and December. Indonesia is located on the “Ring of Fire,” an arc of fault lines circling the Pacific Basin that is prone to frequent earthquakes and volcanic eruptions. -CNN



    Magma plume: large explosions seen at Mt. Etna volcano
    February 9, 2012 – ITALY -Tremor continues to rise (now at 13), from the webcam image, it seems a lava flow is starting to issue from the SE fracture. All indicators point towards we are having the 2nd paroxysm in 2012 during the next hours! The volcanic tremor is now steeply rising (at Cool and vigorous strombolian activity can be seen on the various webcams, possibly a lava flow has started as well. While strombolian activity continues from the New SE crater of Etna volcano, volcanic tremor has started to rise, suggesting a new paroxysm could be in the making in the next hours, although it is still early to be certain. The photo (left) from Boris Behncke was taken during the night of 7-8 February 2012, when the continuing strombolian activity of the New Southeast Crater on Etna was finally widely visible, after about one week of essentially bad weather. Some explosions threw incandescent lava bombs outside the crater, although most were rather weak and all material fell back into the crater. This is a view of one of the stronger explosions observed on the late evening of 7 February 2012, taken from Trecastagni village on the southeast flank of Etna. The activity continued, sometimes vigorously, sometimes more subdued, through the night and morning of 8 February. –Volcano Discovery http://www.volcanodiscovery.com/view_news/5131/Etna-volcano-Italy-strombolian-explosions-from-New-SE-crater-and-increasing-tremor---a-new-paroxysm-.html

    Aleutian Island’s Kanaga volcano awakens- first eruption in 17 years
    February 20, 2012 – ALASKA - The remote Kanaga stratovolcano in the Aleutian Islands might have begun erupting, the Alaska Volcano Observatory (AVO) reports. A possible ash cloud about 39 km (24 mi) NE of the volcano, likely from weak explosive activity, was detected on satellite imagery, and volcanic tremor was detected under the volcano from 15:23-15:27 UTC (6:23 AM AKST) on 18 February, followed by numerous small events for about an hour at Kanaga Volcano. AVO has placed the volcano at Aviation Color Code YELLOW. “This new unrest indicates a possibility for sudden explosions of ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop. If a large, explosive, ash-producing event occurs, the local seismic network, satellite ash alarms, infrasound, and volcanic lightning will alert AVO to the new activity.” Kanaga Volcano occupies the northern corner of Kanaga Island, one of the most southerly members of the central Aleutian chain. It is a symmetric composite cone 1307 m high and 4.8 km in diameter at sea level, built of interbedded basaltic and andesitic lava flows, scoria layers, and pyroclastic rocks. Kanaga Volcano last erupted 1994-1995 when observed eruptive plumes were relatively dilute, rising to altitudes of less than 3 km (9,840 ft) and dropping ash onto the flanks of the volcano. At least two significant ash plumes were recorded over the course of this eruption: the first, to ~7.5 km (24,600 ft) occurred on February 21, 1995 and the second on August 18, 1995, when an eruption cloud reached ~4.5 km (14,760 ft). A light dusting of ash fell on the community of Adak and air traffic was disrupted due to continuing low-level activity and cloudy conditions which prevented visual approaches to the Adak air field. –Volcano Discovery http://www.volcanodiscovery.com/view_news/5531/Kanaga-volcano-Aleutian-Islands-Alaska-possible-new-eruption-detected.html
