Active Icelandic volcano Grimsvotn (Grimsvotn), because of which in a few days, flights were canceled in the UK, Germany and parts of Scandinavia, significantly decreased, but safe to say that the eruption has ceased, there is no way, said Dr. Martin Hensch (Martin Hensch) Volcanological Center, University of Iceland.
Grimsvotn volcano in southeast Iceland, the previous eruption which was recorded in 2004, became more active during the night of May 22. The smoke from the volcano rose to an altitude of 20 kilometers. Earlier Wednesday, Icelandic meteorologists said the Grimsvotn eruption stopped. In spring 2010, the eruption of another Icelandic volcano — Eyjafjallajökull — has led to a Europe-wide aviation collapse.
"The emissions of ash from Grimsvotn crater has now reached the minimum value in the last 24 hours (from 02.00 GMT on the environment). This means that from time to time in the crater there are small explosions, but the ash is no longer released into the atmosphere. Now only steam rises from the crater, "- said Hensch RIA Novosti.
According to him, the seismic activity around the volcano has decreased significantly, and there are currently no signs of new batches of magma ascent from the depths of the earth. Measure the deformation of the volcano using GPS show that the surface of the volcano falls — this means that the pressure in the magma chamber has dropped considerably.
Volcanologist noted that the previous eruption Grimsvotn were the same scenario: explosive start in the first few days, and then the relatively low activity in the coming weeks.
"But we can not say that the eruption has ceased, because until now we capture in the vicinity of the signs of volcanic activity. This activity is limited to the area of the crater … Now we do not think that the activity may rise again. But in any case it is unpredictable "- said the scientist.
He noted that the major predictions for the next few days or weeks is not possible, but scientists will continue to carefully monitor the volcano, as well as for all other Icelandic volcanoes.
Grimsvotn volcano is located in the rift zone Vatnayokudl under the glacier in the south-east of the island. This is one of the most active volcanoes in Iceland, in the last 100 years it has erupted many times, the last time — in 1996 and 2004, small eruptions have also been observed in 1983 and 1998.
The current eruption — the strongest since 1934, and is much stronger than in 2004.
In 2004, the eruption started on November 2 with a series of strong aftershocks, and then rose above the crater of a column of ash and smoke high for about eight or nine miles. Loss of ash was observed at a distance of 150 kilometers from the volcano.
The eruption was accompanied by a flow of water from the glacier, melted volcano. The next day the height of the column of ash and smoke reached a height of 13-14 kilometers, he was visible from Norway and Sweden. However, on the third day of the eruption activity has fallen, the ashes fell on not more than five miles from the crater. Then rose from the crater of steam only, and only 6 November eruption virtually disappeared.
