Iceland's Grimsvotn volcano erupting: assessment of serious effects on the basis of historical data
Sunday, 22 May 2011

Representatives of the Icelandic Meteorological Department said on Saturday, May 21, 2011, that began the eruption of Grimsvotn volcano, located in the southeastern part of the country. According to their research, Grimsvotn volcano threw a column of white smoke to a height of about 9 kilometers.

As reported by Icelandic Meteorological Department, the last time Grimsvotn erupted in 2004, when the height of the emissions from the volcano reached 8 kilometers, this volcano - one of the most active in Iceland over the past 100 years it has erupted 23 times.

Last Grimsvotn eruption occurred in 1996, 1998 and 2004. Subglacial eruption led to intensive ice melting and flooding the area with melt water. Eruption in 1996 caused extensive melting of the glacier, which led to a stream with a flow rate of water 200 000-300 000 m ³ / sec. In November 2004 the eruption was accompanied by massive ejection of ash, resulting in a few weeks was paralyzed air communication with the international airports Reykjavik, Torshavn, and Akureyri.

Yesterday on our website, we wrote an article about how the American evangelist Harold Camping predicted the end of the world at 18.00 21 May 2011. This morning in the media of Iceland wrote, that the eruption of the volcano Grimsvotn really began almost at 18.00 21 May 2011, namely - in 19.10.56 UTC. In this regard, many are interested in answer to the question-what could be the consequences of the volcanic eruption of Grimsvotn? Especially when you consider, that the name of the Grimsvotn volcano translated from the Icelandic - Grimsvötn (grims - dark, vötn - water).

If carefully examine the scientific data on the Grimsvotn volcano, the consequences could be severe, especially given that the last eruption of the Grimsvotn volcano has already led to major disasters. Grimsvotn volcano is located just a few hundred kilometers from the capital of Iceland- Reykjavik. The most important facts in the current eruption is that Grimsvotn linked system of lithospheric fractures with Laki and Katla volcanoes.

Laki volcano–is a thyroid volcano in southern Iceland, near the canyon and the town Eldgya Kirkyubeyarklaustur in the National Park Skaftafell. Laki is a chain of more than 110-115 craters up to 818 m, extending for 25 km, centered on the Grimsvotn volcano and includes Eldgya canyon and Katla volcano. Laki is located between the glaciers and Mirdalsyekyudl Vatnayekyudl in the region of faults, extending from southwest to northeast. In the years 1783-1784 at the Laki and the nearby Grimsvotn volcano there was a very powerful (6 points on a scale eruptions) Fissure eruption with a yield of about 15 km ³ of basalt lava over 8 months. The length of a lava flow was 25-km-long crack -was higher than 130 km and an area flooded with them, amounted to 565 km ². In the air rose clubs toxic fluorine compounds and sulfur dioxide, which killed more than 50% of livestock in Iceland, a volcanic ash fall asleep in part or in whole pasture in most parts of the island. The huge mass of ice melted lava, led to extensive flooding. Famine, which resulted in the deaths of approximately 10,000 people or 20% of the population. This eruption is still considered one of the most devastating in the last millennium and the largest lava eruption in historic time. Volcano erupted fine ash was present in the second half of 1783 over much of Eurasia. Caused by the eruption of lowering the temperature in the northern hemisphere in 1784 led to crop failures and famine in Europe.

Katla volcano, which is also linked Grimsvotn volcano, also caused a major disaster. With the X century there were 14 major eruptions. Last eruption of Katla volcano occurred in 1918, 1934 and 1955. Subglacial eruption led to intensive ice melting and flooding the adjacent areas with melt water. Eruption in 1755 caused extensive melting of the glacier, which led to a stream with a flow rate of water 200 000-400 000 m ³ / sec. For comparison, the average water flow at the mouth of the Amazon river is 220 000 m ³ / sec. It is assumed that the eruption of this volcano was in 10,600 BC responsible for the tephra layer, which is found in geological cores in western Norway, the North Atlantic and Scotland. The total capacity of the layer indicates the amount of rainfall in those areas equal to 6.7 km ³.

Should pay great attention to the fact, that in 920, 1612 and 1821-1823 respectively Katla volcano activity preceded the eruption Eyjafjallajökull, located 20 km from Cuttle and Eyjafjallajökull remember to all the people of Europe to its recent eruption.

On the basis of this observed pattern for the last thousand years, some of Geophysics of Iceland suggest, that the eruption Eyjafjallajökull may be the trigger for the eruption of Katla volcano.

In May 2010, experts of the British Institute for the Study of Natural Disasters has warned, that the beginning of the eruption of Katla volcano. Specialists suggest, that a volcanic eruption of Katla volcano can lead not only to the problems of flight, but also to the melting of glaciers and massive flooding.

If the experts of the British Institute study of natural disasters are right, then the eruption of the Grimsvotn volcano may be the trigger for the beginning of the eruption of another volcanoes- Laki and Katla, and the eruption of these volcanoes might have become the largest natural disasters in recent history.

Plans of U.S. president have changed: the ashes of the Grimsvotn volcano can reach the UK, France, Sweden, Germany and Poland
Tuesday, 24 May 2011 08:14

President Barack Obama leaved the Irish capital from the eruption of Grimsvotn volcano. On the evening of May 23, 2011, Barack Obama broke the Irish part of the European visit and flew to London, reducing the program of his visit to Ireland for a day, as in accordance with the timetable of the European tour of U.S. President, the presidential plane must leave Dublin on May, 24 2011.

Obama was forced to leave Ireland, reported that an ash cloud from the Grimsvotn volcano directed towards the UK. Until further schedule of Barack Obama remains unchanged: from London, where the president will hold two days, he will fly to Paris. Probably, the President of the United States will continue to change the schedule of his tour of European countries.

A few hours ago, the European Aerospace Agency has distributed information about the most probable direction of the ashes from the Grimsvotn volcano in Iceland over the next 72 hours, taking into account the concentration of ash in the atmosphere (see a photos).

Currently, ground radar measurements in Iceland show, that volcanic ash of Grimsvotn volcano reached heights of 12-17 km and travels to Scotland and the coast of France and Germany. The situation was complicated by the fact, that last night in South-eastern Iceland, the weather has deteriorated and have squally gusts of wind.

According to projections, made a few hours ago, given the wind directions in the Grimsvotn volcano in Iceland, it is evident, that this morning the ashes of the Grimsvotn volcano reached the north of Great Britain and Greenland, and tonight the ashes of the Grimsvotn volcano will reach the south of Sweden, north of Germany and Poland. It is projected (see a photos), two days later the situation might deteriorate and the ashes of the Grimsvotn volcano can cover a large part of the UK, and then some Nordic countries, but the concentration of ash in the atmosphere and it is expected low.

However, not all scientists agree that the Nordic countries will feel the presence of volcanic ash of Grimsvotn volcano, for example, as reported by Fred Prata of the Norwegian Institute of Atmospheric Research :"... the eruption Grimsvotn was thrown more ash, than the eruption of Eyjafjallajökull year earlier, but the ashes of the Grimsvotn volcano heavier, so more of the ashes of the Grimsvotn volcano rolled around Iceland, and will not be transferred to European countries, as was in the case with the Eyjafjallajökull volcano year earlier. "

In past years, the eruption of the Grimsvotn volcano continued for several days, and they do not lead to disruptions in the international air communication. The last eruption of the Grimsvotn volcano happened in 2004. Usually, the ashes rises above the Icelandic volcanoes at heights up to 20 kilometers and then carried by air currents for hundreds or thousands of kilometers from the epicenter of the eruption. Ash deposited from the air precipitation. If the concentration of ash in the air was great, land-surface forms a layer of ash. Near the volcano for a single eruption could settle layer of ash and larger pyroclasts thickness in meters and even a few tens of meters, and now scientists are watching in Iceland, directly adjacent to the volcano Grimsvotn. With increasing distance from the volcano, the ash concentration in the atmosphere decreases with the square of the distance, and the thickness of ash layers decreases rapidly.

According to scientists, is now a volcanic eruption poses no danger to air traffic in Europe, but in the coming days will be checked, whether in the atmosphere of a dangerous concentration of ash. Currently, the situation with the clouds of volcanic ash monitor meteorological satellites in continuous mode. Help them weather stations, launched on balloons and ground stations, equipped with lidars (laser radars). All data are promptly processed and delivered to the air navigation services in Europe, which, in turn, notify the pilots of hazardous concentrations of volcanic ash that may arise on the path of aircraft. Simultaneously, the airline ordered to conduct more thorough inspection of engines for possible damage.

We have already reported on our website, that eruption of Grimsvotn volcano may be the trigger for the eruption of a more powerful eruption in Iceland- the eruption of Katla volcano. Recall that the subglacial Katla volcano leads to rapid ice melting and flooding in adjacent areas with melt water. Eruption of Katla volcano in 1755 caused extensive melting of the glacier, which led to a stream with a flow rate of water 200 000-400 000 m ³/sec. Therefore, European researchers a few days ago was launched round the clock monitoring of the Katla volcano.

Grimsvotn volcano canceled flights in Europe: perspectives on the further development of the situation
Tuesday, 24 May 2011 14:44

Today were canceled flights from airports in Glasgow, Edinburgh and Aberdeen in Scotland, as well as in the airports in Dublin, Cork and Shannon in Ireland, currently canceled 252 flights in Europe.

Scottish Loganair canceled 36 flights, a temporary suspension of flights between Scotland and England in the UK said British Airways. KLM in the Netherlands also reported about abolish of 16 flights to Scotland, EasyJet announced the cancellation of flights to the Edinburgh and Glasgow in Scotland. Today were closed two airports in Norway, which serve oil platforms in the underwater shelf of Norway. Yesterday, for the same reason, the Norwegian authorities canceled flights between mainland and Svalbard.

Risk of violation of air traffic in Northern Europe, has forced U.S. President Barack Obama to shorten his stay in Ireland.

According to the Meteorological Service of Iceland, the intensity of the eruption of the Grimsvotn volcano remains the same, while a column of smoke down to a height of 5 kilometers (formerly ash rose to an altitude of 20 kilometers).

According to projections, it is expected, that the ashes of the Grimsvotn volcano tonight to reach the south of Sweden, north of Germany and north of Poland. It is projected (see a photos), that two days later the situation might deteriorate and the ashes of the Grimsvotn volcano can cover a large part of the UK, and then the southern regions of Norway, Sweden and Finland, as well as northern parts of France, Germany and Poland, but the ash concentration in atmosphere it is expected negligible (see a photos). As reported by the Meteorological Service of Germany a few hours ago, the concentration of volcanic ash will be from 0.2 to 2.0 micrograms per cubic meter of air, at this concentration plane flights are only possible in the implementation of special supervision for their safety.

Yesterday, the Organization for Supervision of Safety in Europe (Eurocontrol) reconvened a special organization to coordinate in the case of aviation crisis (European Aviation Crisis Coordination Cell), created during the eruption of an Icelandic volcano in 2010. But, unlike in 2010, Eurocontrol has decided to allow airlines to make their own decisions about the termination of operations in the areas of contamination of ash, on the basis of safety assessment, produced by the authorized operations in each country. For example, the British Civil Aviation has already established a level of concentration of volcanic ash in the air, which should discontinue flights: a complete ban on flights is provided by the contents of 0, 4 grams of ashes or more in 1 cubic meter of air.

Currently, the situation with flows of volcanic ash from the Grimsvotn volcano, track weather satellites around the clock. Also launched a meteorological station on balloons and organized the work of ground tracking stations equipped with lidars (laser radar). All data are continuously processed and sent to the air navigation services in Europe, which, in turn, notify the airlines of the concentrations of volcanic ash in some parts of Europe. Also ordered airlines to conduct more thorough inspection of aircraft engines, for possible damage.

Despite the cancellation of many flights (currently canceled 252 flights to Europe), the UK authorities are not going until completely closed its airspace. Air control agency of Great Britain claimed, that the route of movement of ash clouds from Grimsvotn volcano impossible to predict and the situation remains uncertain. Thus, is not yet known whether the canceled flights departing and arriving in the UK. It is also not going to close, and yet the transatlantic air communication with America. It is expected, that the ashes will reach the north of Russia, but air travel does not hurt if the force of the eruption will not increase.

Puyehue Volcano awoke in Chile: impact assessment
Sunday, 05 June 2011 06:18
On June 4, 2011 began an eruption of Puyehue Volcano, located in southern Chile, at 870 kilometers from the capital Santiago. Puyehue Volcano is located on the Chilean side of the Andes. According to the National service of Geology and Mining of Chile, column of ash rose to high of 10 km, the air is a strong smell of sulfur. The level of threat in the area of the Puyehue Volcano raised to a maximum.

The authorities organized the evacuation of about 3500 people in San Carlos de Bariloche. San Carlos de Bariloche - is the famous resort of Argentina, which is located in the Andes, in 1,6 thousand kilometers from the capital of Argentina. San Carlos de Bariloche annually attracts tens of thousands of local and foreign tourists. According to the residents of this resort town: "... volcanic ashes strewed on the town like snow in a blizzard." Streets of San Carlos de Bariloche covered with a layer of ash at 10 inches. According to authorities, more than 40 years was not observed anything like that, in the last time the Puyehue Volcano erupted in 1960, after the biggest earthquake of magnitude 9.5. Local authorities have closed the airport and a popular border crossing between Chile and Argentina, located on the pass in the Andes. The Chilean authorities have also conducted evacuation of civilians from the surrounding areas. Authorities urge residents to keep calm, do not leave the house, do not open the windows and if possible to refrain from driving directions.

It should be noted, that in Chile are 15% of all active volcanoes in the world, and volcanic eruptions, and not such a rare event in this country. In Chile, there are over 2,900 volcanoes, from small ash cones to large calderas of several tens of kilometers in diameter, 500 volcanoes are weakly active, while 80 are in the phase of highest activity. Of the 80 volcanoes can wake up and start to erupt in the near future. The most active Chilean volcanoes are: Laskar in northern Chile and a chain of volcanoes in central-southern zone - Chillán, Antuko, Cayaqui, Copahue, Solipuli (Sollipulli), Villarrica ( Villarrica), Lyayma (Llaima), Lanin (Lanín), Lonkimay (Lonquimay), Mocho (Mocho), Chosuenko (Choshuenco), Puyehue, Antillanca, Osorno, Calbuco, Hudson. The first historical mention of the eruption of a volcano in Chile relates to 1624, when the Antuko volcano, called in those days Angol, within 8 days of throwing out smoke and lava, and the "land of buzzing, roaring as if the devil himself", according to the description of monks Jesuits. Lyayma Volcano erupted in 1640, 1750 and 1765.

Over the past 450 years in Chile, there were more than 300 volcanic eruptions. Sometimes the consequences were terrible: the ashes buried pasture, destroying livestock and crops, lava flows flooded entire towns and villages, burned forests, varied terrain of mountains and valleys, creating fantastic geological structures, which attract many tourists today.

The most dangerous of statistics, was the Villarrica volcano, which claimed in 1948, about a hundred lives, and in 1964 the eruption of this volcano led to the deaths of 22 people. This latest eruption devastated the Konyaripe village, two hours razed houses, hotels, and crops, killing livestock and agricultural equipment and cutting off communication with the so popular now resorts in Villarrica and Pucon.

Particularly troubling experts is the fact, that the earlier eruption of the Puyehue Volcano caused eruptions of other volcanoes, as documented in 1790- after the eruption of Puyehue Volcano, began erupting Lyayma volcano. A seismic activity near Lyayma volcano, located in southern Chile, according to the National service of Geology and Mining of Chile- again increasing. A new burst of volcanic activity of Lyayma volcano, located about 700 kilometers from Santiago, says the increased flatulence and a strong buzz that is heard from under the ground. It was so in January 2008, then began the first eruption of Lyayma volcano. Then it was repeated in June 2008. The eruption of the Lyayma volcano in 2008, which is considered one of the most active in South America, from the area were evacuated residents and tourists.

Currently, Argentina Hydrometeocentre predicts, that a cloud of ash from the eruption of Puyehue Volcano can cover a significant part of the country's inland provinces, which border with Chile, with the wind direction changes and it can reach the capital - Buenos Aires, but the concentration of ash will remain harmless.

The presidents of Argentina and Chile have agreed to collaborate in taking the necessary measures and assist victims. In the disaster zone delivered drinking water and foodstuffs.

Volcanic eruptions is very natural disasters, for example, is currently the most dangerous in the world is the Cumbre Vieja volcano on the Canary Islands, the eruption of Cumbre Vieja volcano could theoretically cause a giant tsunami up to 900 meters, with a speed of 800 km / h. West Africa in this case will cover a wave height of 100 meters, the United States - the height of 50 meters, and Britain - the height of 12 meters.

A cloud of ash from the Nabro volcano in Eritrea reach the countries, located on the Mediterranean coast
Wednesday, 15 June 2011 07:19
According to recent reports, the effects of eruptions of Nabro volcano in Eritrea (Africa) may be larger, than originally anticipated.

Yesterday, the ashes of the Nabro volcano, which began erupting on June 12, 2011 in Eritrea, reached the cities of Abu Simbel, Aswan and Luxor in the south of Egypt. According to the BBC, the Egyptian airline Egyptair currently has canceled flights to the cities of the Sudan, Eritrea and Ethiopia, have also been re-route flights to other African countries. Several Israeli media also reported, that the cloud of ash from the Nabro volcano today has already reached of southern Israel, which is also in the short term may affect the schedule and route of flights from the Middle East.

It should be noted, that initially the nearest monitoring volcanic activity, located in Toulouse, France announced the start of the eruption on June 12, 2011 the Dubbo volcano. Dubbo volcano is active volcano in Eritrea, located 23 kilometers south of the Red Sea. But already on June 13, was informed about eruptions of Nabro volcano in Eritrea.

Nabro is a volcano, located in the northern Red Sea near the border of Eritrea and Ethiopia. Eruption of Nabro volcano preceded by a series of earthquakes with magnitudes up to 5.7 points. The eruption of the Nabro volcano spewed ash to a height of 15 km. At present there are no historical evidence of a volcanic eruptions of Nabro volcano,since the last eruption of Nabro volcano occurred about 12 thousand years ago, and the eruption of this volcano is now caused a big surprise to scientists. Even at the Center for monitoring of natural hazards of NASA did not expect a volcanic eruption in this region, therefore, by coincidence, U.S. Secretary of State Hillary Clinton arrived in Ethiopia, almost simultaneously with the beginning of a volcanic eruption of Nabro volcano on the border of Ethiopia and Eritrea, and the next day, U.S. Secretary of State was forced to interrupt his tour of Africa, as a cloud of ash from the Nabro volcano moved to the capital of Ethiopia, where there was Hillary Clinton.

Scientists are paying attention to the fact, that Nabro volcano is not a simple volcano, Nabro - is a volcanic caldera in the northeastern part of the East African Rift Valley. Volcanic calderas are round or oval shape, reaching several kilometers in diameter and surrounded by a low ridge from the remnants struck the cone of the volcano.

According to the latest NASA imagery (see a photo), the ash from the Nabro volcano movement of air masses moves to the side of Egypt, Libya, Greece, Italy, France, so may be cancel some flights to these countries, as well as reduction of air strikes by NATO forces in Libya. Part of the ash movement of air masses moves to the side of the Middle East countries, it is probably of cancellation of flights in the Middle East countries, especially located on the cost of Mediterranean Sea. Therefore, if the eruption of Nabro volcano will not stop, there is a probably of reducing the flow of tourists to the resorts of the Mediterranean Sea, due to the cancellation of flights.

It should be noted, that the Nabro volcano is not the only volcanic hazard for Europe, according to the latest pictures taken a few minutes ago, at the time of this writing, there is sluggish activity of the Etna volcano in Italy, is even seen as above the Etna volcano rises plume. And Etna volcano - it's not a small Nabro volcano, Etna volcano- is the largest volcano in Europe, which covers an area of 1250 square kilometers.

According to Italian media, "friendly" nature of the Etna volcano is changing. Despite the fact, that over the past hundred years, the nature of Etna volcano was pretty quiet, but now the behavior of Etna volcano, which previously was considered active, but not dangerous, it becomes increasingly suspicious and Italian volcanologists warn that the nature of the eruptions of Etna volcano ranges from effusive in which the lava poured onto the surface slowly and stands a little volcanic gases, to the explosive. And Europe is already one, about 3.5 million years ago survived a powerful explosive eruption of Santorini volcano, when a big wave of a tsunami, caused by the explosion of the Santorini volcano, swept away many of the towns and villages on the island of Crete and all the Mediterranean coast.

But while the activity of the Etna volcano is not passed into the active phase, so can not speak of repeating the scenario of Santorini volcano.

In Australia, found the skeleton of a giant wombat: the history of death
Thursday, 07 July 2011 00:01
BBC reported that, in the north of the Australian state of Queensland, was found almost completely preserved skeleton of a giant marsupial (Diprotodon optatum), resembling a giant wombat, which lived more than 50 thousand years ago.

Professor Mike Archer from the University of New South Wales reported, that the marsupial was herbivores, its dimensions are comparable with the car and weighs was about three tons. For the first time in Australia was found a complete skeleton of the oldest inhabitant of Australia. Due to the fact, that this finding was found in a place, where were found many representatives of the Australian megafauna of this period, this finding is not only paleontological interest, but also can serve as a basis for understanding, what a disaster caused such a massive extinction of many species of Australian megafauna a tens of thousands of years ago.

Here is a new version of the death of megafauna, which first appeared only two days ago, namely- on July 5, 2011 in South Australia, 96 km south-east of Melbourne in the same place, there were two earthquakes of magnitude 4.6 and 3.7. Particular attention is attracted by these Australian earthquakes because they happen to spot of long extinct volcanoes, which last an estimated erupted thousands of years ago. And we know, that earthquakes in the vicinity of volcanic eruptions may be harbingers of these volcanoes.

As reported by a team of scientists from the University of Melbourne – in Australia could soon wake up the dormant volcanoes, as volcanic eruptions have occurred previously in Australia every 2000 years, but the last volcano woke up more than 5000 years ago. If you look at the location of volcanoes in Australian territory, it immediately apparent that Queensland, where was found a fully preserved skeleton of a giant marsupial (Diprotodon optatum) is literally full of extinct volcanoes- in Queensland there are about 400 volcanoes.

Queensland is a state in north-eastern Australian mainland. In Queensland there are five security zones of World Heritage sites: The Australian Reserve fossil mammals in the Gulf Country, Central Eastern Rainforest Reserve, Fraser Island, Great Barrier Reef and the Wet Tropics of Queensland. So there are good reasons to assume, that Queensland was the last refuge of the representatives of the ancient megafauna of Australia, who could find in this state for some meager sustenance from its proximity to the equator and humid climate.

The ancient catastrophe, that led to the deaths of many animals of Australia, are probably came from the south of Australia, and it is very likely, that this was a major volcanic eruption somewhere in the south of Australia. The main cause of death was a volcanic ash, covering large areas of Australia.

It should be noted, that smaller species of Australian wombats were more likely to survive the disaster than the giant wombats, as wombats (Latin Vombatidae) are Australian marsupials, they are short-legged, muscular quadrupeds. They are adaptable in their habitat tolerances, and are found in forested, mountainous, and heathland areas of south-eastern Australia. Because of the structure of muscles, divided upper lip allows wombats easily and accurately choose what they eat, and the front teeth wombat can reach right down to the ground and cut even the smallest shoots of plants. A particularly important role in the selection and search for food at night wombats playing active sense of smell. The metabolism of wombats is very slow and effective. To digest a food, even modern wombats need up to 14 days. Wombats are currently the most economical water users of all mammals on Earth, after the camel: for wombats enough 22 milliliters of water per kilogram of body weight per day. Even the kangaroos, which are perfectly adapted to the harsh life in Australia, are spending four times more water.

As a result of a volcanic eruption in Australia, were covered with volcanic ash huge tracts of its territory because of what the giant wombats, because of its economical expenditure of energy (for sure wombats were not required to eat every day), survived for several weeks more, then large predators, which allowed to survive the skeleton of wombat, as small predators were not able to physically pull apart its.

Thus, the finding is a skeleton of a giant wombat suggests the presence of sudden and rapid disaster is likely a powerful volcanic eruption, which occurred somewhere in Australia about 50 thousand years ago. And the day before yesterday two earthquakes in the same place cause to pay attention to this region of the Earth, because such a disaster could happen again and sudden awakening of volcanoes in Australia can cause a lot of trouble for Australians.

Kilauea volcano woke up in Hawaii
Friday, 05 August 2011 14:58
http://hainanwel.com/en/unusual-world/7 ... lcano.html 

In Hawaii woke shield Kilauea volcano, which is located near the more powerful of the Mauna Loa volcano. The last major eruption of Kilauea was in 1983, but since hot lava from a volcano appears periodically. Kilauea volcano last woke up in March this year, but the new eruption of lava from the volcano Kilauea exceed in size eruption in March, according to scientists,lava struck out in the rock and appeared a crack at a few hundred meters in length, from which it is happening now and ejection of lava. Hawaiian volcanic laboratory has reported, that the eruption of Kilauea volcano is not a threat to local residents.

Scientists can to predict of volcanic eruptions
Saturday, 29 October 2011 17:54

http://hainanwel.com/en/unusual-world/1 ... tions.html

A group of scientists from Florida Institute of Technology and from University of Hawaii at Manoa, with the support of the NOAA has created an information system, that can predict the power of the eruption of various types of volcanoes. According to scientists, each type of volcanic eruption at different power, produce of different infrasound with certain range, before the upcoming eruption. Infrasound caused by movement of magma to the crater of the volcano and the state on the eve of the eruption is characterized by the appearance of subsonic in certain frequency bands. However, the main problem so far boils down to what can be more reliably predict the eruption of the volcano, which erupted earlier and the scientists were able to record infrasound before their eruption. In the world gathered a large number of instances, when the animals leave the territory near volcanoes before the eruption of volcanoes, animals could probably feel some infrasound, informing them of the coming eruption. But scientists hope, that their information system built on the basis of artificial neural networks will reveal more general criteria for predicting the eruption of all the volcanoes on Earth.

Axial volcano near Oregon will begin to erupt in 2018
Monday, 11 June 2012 12:30
http://hainanwel.com/en/unusual-world/1 ... lcano.html

A team led by William Chadwick from the University of Oregon, USA predicts eruption of Axial volcano near the coast of the North American state of Oregon in 2018. The confidence of researchers confirms the current activity of the Axial volcano, which repeats its performance after the last eruption: the average growth rate of the bottom-level of 1.2 meters per year, indicates, that the next eruption of Axial volcano will be happened seven years later- in 2018. Scientists estimate, that the future of the eruption in 2018 may exceed the consequences of volcano Eyjafjallajökull eruption in 2010, which may interrupt the flights in this region of the Earth.

Group of geologists led by David Pyle from the University of Oxford, United Kingdom reported an unusually high speed filling the magma of reservoir under the Santorini supervolcano in the Aegean Sea, Greece. Santorini - is acting thyroid volcano on the island of Tyre, also known as Thera in the Aegean Sea, the eruption of which killing Aegean towns and villages on the islands of Crete, Tyre, and the Mediterranean Sea about 1645 BC - 1500 BC (according to various estimates). On power eruption of Santorini had 7 points, which is comparable with the eruption of Tambor and 3 times stronger, than the eruption of Krakatoa. It is considered, that the eruption destroyed the Minoan civilization on the island Crete and caused a huge tsunami of about 100 meters, the ash cloud extended to 200-1000 km. Group of geologists led by David Pyle of the University of Oxford for the first time noticed to Santorini volcano in January 2011, when the sensors on one of the islands in the Aegean Sea have recorded a series of small earthquakes, so in early 2011, David Pyle and his group went to Santorini and more than a year studying the state of Santorini volcano and watched it's activity on the basis of surface data and data of satellite monitoring. According to scientists from the University of Oxford, increased activity of the Santorini supervolcano in 2011 has led to an increase height of some islands in the Aegean Sea by 7-15 inches in just a few weeks, due to the fact that the magmatic Santorini volcano chamber was filled with magma in the record, not previously observed period, the volume of magma is estimated at 15-20 million cubic meters. Previously, for this amount of magma required considerably longer for 2011 Santorini volcano accumulated so much magma as before going under it for 15-20 years.
