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.
