    Double eruptions: Kamchatka’s Shiveluch volcano unleashes 8 km ash cloud,
    Anak Krakatau 3 km

    October 4, 2011 – RUSSIA – Kamchatka volcano Shiveluch has emitted a column of ash up to 8km high. There is no danger for the local population. No volcanic dust fall has been registered in the nearby villages, the Kamchatka branch of the Geophysical service of the Russian Academy of Sciences reported on Tuesday. Last time Shiveluch became active in May 2009 and since then emissions of gas, ash and even lava have been occurring on a regular basis. -VOR


    Indonesia- Anak Krakatau, a volcanic island in the Sunda Strait between the islands of Java and Sumatra in Indonesia, erupted on Tuesday sending columns of ash and rock hurtling high into the air. The rise in volcanic and earthquake activity prompted authorities to put in place a 2km exclusion zone for tourists and local fishermen. The Indonesian Volcanology and Geology Disaster Mitigation Centre reported that an estimated 6,000-7,000 volcanic earthquakes were recorded daily during the weekend and on Monday. Daily earthquake totals usually do not exceed 100-200. Seismologists are still attempting to determine the type and scale of the ongoing eruption. -IWO

    Iceland’s Katla volcano rattled by strongest swarm of quakes yet



    October 5, 2011 – ICELAND – A sharp series of earthquakes, including a 4.0 magnitude tremor, began shortly before 3 am last night in the northern Katla caldera below Mýrdalsjökull glacier in south Iceland with the first quake measuring well over three points on the Richter scale, according to geophysicist Benedikt Ófeigsson who was called out to the Icelandic Meteorological Office. Ófeigsson said a few other earthquakes measuring around three points on the Richter scale followed but activity then subsided, only to pick up again at 3:30 am and again at 5:30 am, but in both those instances the earthquakes were weaker than during the first series, visir.is reports. Therefore, it was not considered necessary to alert the Civil Defense Department, Ófeigsson explained, although the events of the night will be reviewed there this morning. The inhabitants of Vík in south Iceland have drilled evacuation procedures in case of an eruption in Katla, as a glacial outburst from Mýrdalsjökull might flood the town. –Iceland Review http://www.icelandreview.com/icelandreview/daily_news/Sharp_Series_of_Earthquakes_in_Katla_Volcano_0_382875.news.aspx

    Analysis of a mega-tsunami generated in the canary islands.
    According to this PDF report 20-25m wave heights would be expected on the eastern seaboard.

    Cumbre Vieja Volcano -- Potential collapse and tsunami at La Palma, Canary Islands
    Steven N. Ward Institute of Geophysics and Planetary Physics, University of California, Santa Cruz California, USA
    http://wet.kuleuven.be/wetenschapinbreedbeeld/lesmateriaal_geologie/wardday-lapalmatsunami.pdf


    Abstract. Geological evidence suggests that during a future eruption, Cumbre Vieja Volcano on the Island of La Palma may experience a catastrophic failure of its west flank, drop- ping 150 to 500 km3 of rock into the sea. Using a geologically reasonable estimate of landslide motion, we model tsunami waves produced by such a collapse. Waves generated by the run-out of a 500 km3 (150 km3) slide block at 100 m/s could transit the entire Atlantic Basin and arrive on the coasts of the Americas with 10-25 m (3-8 m) height.

    Krakatau, Indonesia – volcanic earthquakes are creating unrest in coastal villages

    SNIP: The PVMBG specialists who are guarding the volcano are saying however that a violent eruption generating a tsunami is highly unlikely at this alert level (krakatau is an island and a huge part of the volcano is below sea level). Many coastal villages in the Sunda strait are very scared that this volcano with a violent past will explode again. Scientists can predict volcano eruptions fairly good today. GPS recordings which show an eventual deformation of parts of the volcano are giving a good hint in the potential danger.

    The inhabitants of the coastal villages have been told by the scientists that they should calm down because a major eruption like the 1883 is highly unlikely at this moment. END SNIP

    El Hierro on the brink? 9,300 tremors have rattled the island since July

    October 7, 2011 – CANARY ISLANDS – Intense swarms of tremors beneath one of the volcanic Canary Islands has placed residents of El Hierro on alert for a possible eruption. Spain’s Instituto Geografico Nacional (IGN) reported the 9,300 seismic movements on the island since July 17 have caused measurable changes in the terrain. El Hierro’s only eruption during recorded history was in 1793, when the Volcano de Lomo Negro vent rumbled for a month and produced lava flows. Seismologists say they don’t know if the rising ball of lava causing the latest rumblings will break through the surface, but they have issued a “yellow” alert as a precaution. IGN Director Maria Jose Blanco told reporters that any eruption would most likely have a “low explosive value.” Tremors about 50,000 years ago produced an enormous landslide that cascaded into the ocean, creating a large tsunami that probably reached the North American coast. –Earth Week

    Underwater eruption taking place off the coast of El Hierro

    October 10, 2011 –CANARY ISLANDS – A submarine volcanic eruption is taking place approximately 5 kilometers off the southern coast of El Hierro, the smallest of The Canary Islands. The Mayor of La Frontera (El Hierro), David Cabrera, confirmed in an interview on Radio iron Garoé that ‘underwater eruption’ is taking place about 900 meters beneath the sea surface five kilometers south of La Restinga. The eruption has been ongoing for four hours, the Mayor said. Spanish newspaper laopionion.es quoted the Minister of emergencies of the Cabildo of El Hierro, Maria of Carmen Morales, as saying the eruption is taking place because ‘the seismic movement of 4.3 occurred on Saturday afternoon caused a fissure, from where the energy is been released’. Scientists remain unclear if the emissions are gas or lava. Reports near the vicinity tell of changes in the sea and waves. A meeting of PEVOLCA – Actualidad Volcánica de Canarias, comprising representatives of Instituto Geografico Nacional (IGN) and The Canary Islands Government, is presently taking place on the Spanish Island. Meanwhile, La Agencia Estatal (CSIC) scientists equipped with special detection cameras have been making numerous sorties over coastal areas of El Hierro in an attempt to verify the existence and scale of the underwater eruption. This is Spain’s first volcanic eruption since 1971 when the erupted of the Teneguía volcano on the island of La Palma (Canary Islands), located to the north of El Hierro. Initial reports of the eruption were received from crews on board four separate ships. On Monday afternoon, Terra Noticias/Agencia EFE reported that an eruption occurred 2000 meters below sea level in the Las Calmas sea at 10.43 local time (05:43 EDT). Spanish newspaper El Mundo placed the depth of the eruption at 13oo meters. local media agency Canarias7 reported on Monday that Government authorities have suspended ferry activities to and from the 285 square-kilometer island. English language newspaper islandconnections.eu reported: “The maritime chief for the province of Santa Cruz de Tenerife Antonio Padrón has issued a recommendation that boats should not sail closer than four miles off El Hierro. Divers have also been told to suspend all activities. -IWO

    Anak Krakatau reaching danger zone as tremors approach 6000

    October 9, 2011 – INDONESIA – Anak Krakatau volcano monitoring post reported Saturday increasing volcanic tremors at the famous volcanic island, located in the Sunda Strait between the islands of Java and Sumatra. Head of the volcano monitoring post in Pasauran, Serang, Banten, Anton S. Pambudi said that the tremors had reached 5,883 on Saturday evening. “Data recorded at a monitoring post on Oct. 8 shows that 5,883 tremors came from the volcano as compared to 5,543 and 5,204 in the previous days,” an official at the Anak Krakatau volcano monitoring post in Cinangka, Serang, Banten, Anton S. Pambudi, said Saturday as quoted by Antara news agency. Despite increasing volcanic activity, the the Volcanology and Geological Disaster Mitigation Center (PVMBG) has yet to further raise the level of alert status of the volcano. “We maintain the alert status on Siaga, which means that we prohibit local residents or visitors from approaching the volcano up to two kilometers in radius,” Anto said. The authorities have raised the status of Anak Krakatau, which is Indonesian for ‘Child of Krakatoa’, to alert, the third of four alert levels, on Sept. 30. “We call the residents not to panic despite the frequent tremors. But, we tell them not to approach the volcano’s 2-kilometer radius,” he said. Meanwhile, residents living along the coast of Anyer admitted that they did not worry about the tremors. “My family and I felt no difference compared to the situation before the authorities raised the alert status,” said Doni, a resident of Paku, Anyer. Anak Krakatau erupted briefly on Tuesday spewing ash and rock high into the air. The eruption was the biggest since January 2011 when ash was emitted more than 600 meters into the air, forcing the evacuation of tens of thousands of residents. Last year, the volcano also erupted on Oct. 29 forcing the authorities to raise the alert status of the volcano. The volcanic island exploded in 1883, killing approximately 40,000 people. –Asia One

    October 9, 2011 – CANARY ISLANDS – A 4.3 magnitude earthquake struck El Hierro, the smallest of The Canary Islands, late on Saturday night. It was the strongest earthquake to be recorded on the Spanish island since an unprecedented earthquake swarm commenced during the summer. The Instituto Geografico Nacional (IGN) has reported an increase in the intensity of earthquakes recorded on El Hierro, the smallest of The Canary Islands, during the last 48 hours. The number of earthquakes recorded since July 17 , 2011 on El Hierros has now reached 10,000, figures from the IGN confirm. The IGN also confirmed surface deformations exceeding 35mm on the 280-sqkm island, where residents have been put on alert for a possible volcanic eruption. However, seismologists have moved to reassure the local population that a volcanic eruption is not imminent. The agency confirmed on Friday that 886 earthquakes, most of them located in the sea to the SW of the island, have been recorded in the 7 days since 02 October, 2011. During this period, 71 earthquakes were felt by the island’s estimated 10,000 residents. Since Friday morning, there have been more than two dozen earthquakes exceeding 3.0 on the Richter Scale with epicenters both North and South of the NW Ridge and depths between 10 and 15 km have been recorded. The strongest of the tremors measured 4.3 magnitude on the Richter Scale, many times stronger than other earthquakes recorded on the island since mid-July. It was recorded on Saturday night at a depth of 12 km. The quake produced small rockslides but no injuries were reported. -IWO

    MADRID-- Officials say they are evacuating some 600 residents from a small coastal town on the Spanish Canary island of Hierro because of volcanic activity in the area.
    Tuesday's decision by the regional government to evacuate La Restinga town came after the National Geographic Institute confirmed there was an undersea eruption some 3 miles off the coast Monday and that another eruption closer to Hierro island is possible.
    No damage was caused by Monday's eruption.
    Hierro, with 11,000 residents, has been on alert level 2 in a scale of 4 in recent weeks for fear of an eruption, but officials insist an eruption is not likely to be major.
    The Canary Islands lie off the coast of northwest African and were formed by volcanic activity. Hierro has some 500 volcanoes.

    Magma plume: 5.1 magnitude earthquake strikes near Easter Island

    October 11, 2011 – Easter Island – A 5.1 magnitude earthquake struck the region of the Easter Island at a depth of 13.6 km or 8.5 miles. The number of magma plumes or ‘hotspots’ now recording seismic or volcanic activity due to a flux in the planet’s thermal gradient is increasing as our above map from a month ago of the planet’s hotspots prove. Easter Island is the latest flashpoint. I warned this would happen at the planet’s hotspots back in May of this year. That was 2 months before seismic activity began erupting on the island of El Hierro on July 17.



    May 1, 2011 – They are called hotspots or magma plumes and they are deep cavities in the planet’s mantle that vent magma. They are the clearest way to gauge the planet’s temperature and pulse. Increased seismic activity in these regions signals planetary interior gradient along with magmatic pressures are rising.
