Why ten countries of Europe were forced to close the air spaces in whole or in part?In Iceland after 200 - summer “ hibernations “ the volcano Eyjafjallajokull woke up. Eruption began on March 21, 2010 and was so powerful that in the country imposed state of emergency and evacuated hundreds of inhabitants of nearby settlements.
began on April 14 the new eruption which was followed by emission in the atmosphere of a huge amount of ashes. Next day ten countries of Europe were forced to close in whole or in part the air spaces - in particular, flights were cancelled at the airports of London, Copenhagen and Oslo.
Eyjafjallajokull (Eyjafjallajokull) means “ Island of mountain glaciers “. The volcano is located in 200 kilometers to the East from Reykjavik between glaciers Eyjafjallajokull and Mirdalsyokudl. These are the largest glacial caps in the south of the northern island country covering active volcanoes.
Vulcan Eyafyatlayokudl represents a glacier of conical shape, the sixth in size in Iceland. Height of a volcano makes 1666 meters. Diameter of a crater is equal to 3 - 4 kilometers, a glacial covering - about 100 square kilometers.
Iceland lies on Is median - the Atlantic ridge where quite often there are eruptions of volcanoes. In this country almost all types of the volcanoes which are found on Earth are presented. Glacial caps and other glaciers occupy the space of 11 900 square kilometers.
As many volcanoes of Iceland are covered with glaciers, often they waterlog them from below. Languages of glaciers break from the places, letting out millions of tons of water and ice which take down everything on the way.
For these fears after Eyafyatlayokudl`s pro-box in 2010 in Iceland so serious security measures were taken. In particular, after its March eruption the movement on nearby highways was stopped and inhabitants are evacuated. Local authorities were afraid that the volcanic lava will kindle a glacier and will cause severe floods.
However after the conducted researches experts came to a conclusion that eruption does not pose threat for locals. Several days of the power later allowed people to return to the houses.
Volcanists could approach a crater on distance of several meters and film eruption with the camera, they saw that the crack which leaves a lava has length about 500 meters. the Icelandic scientists long time watched
a volcano, tracing signs of seismic activity. In their opinion, eruption can last about a year more or even two. The last eruption of Eyafyatlayokudl was registered in 1821. Then it lasted up to 1823 and caused the menacing thawing of a glacier. Besides, from - for high content in its emissions of compounds of fluorine (fluorides) threat to health, namely bone structure of people and a livestock was created.
If current eruption proceeds also long, then the air space over Europe should be closed and opened periodically, depending on activity of a volcano, professor Bill McGuire, the expert of the center for studying of natural cataclysms at the London University college warns.
