Iceland — A deep earthquake occurred in the Icelandic volcano Hofsyekudl.
The volcano has never erupted in the whole of recorded history. Geologists believe that the last time he was active in the Holocene (Holocene Epoch ended about 11,000 years ago —approx. translator:). Ice dome volcano is very deep. Its lowest point is at a depth of 650 m The deepest point of the glacier located in the main caldera. If Chaiten volcano in Chile, but something has taught scientists, it is clear that dormant volcanoes need a little time to go from dormant to active eruption. That's why I have a concern that the deep earthquakes began to occur on the volcano Hofsyekudl, even to this day, they are extremely rare.
Over the last 10 years or more was observed slight increase in activity at the volcano Hofsyekudl earthquakes along with the increase of hydrothermal activity. By the standards of the Icelandic volcano Hofsyekudl most complex of all volcanoes. South of the volcano Kerlingafyedl. This volcano is well known for its high hydrothermal activity. The volcano is located along Hofsyekudl area extending from west to east, at the junction of two major rift zones of Iceland. It serves as a "bridge" between the Reykjanes-Laungyekudl fault to the west, ending at the glacier Laungyekudl and eastern area, passing through the east-central Iceland. Apart from the fact that the volcano is one of the largest in Iceland, it is also extremely dangerous volcano because of its location. As it is located in the center of Iceland, glacial flood, coming from him can head in different directions to the ocean through densely populated areas in Iceland.
Deep earthquake occurred near the caldera. Earthquake under the volcano Hofsyekudl occurred April 5 at 10:11 am for universal time at a depth of 27.6 km. The earthquake was weak and its magnitude was 1.4 on the Richter scale. But I do not believe that this was a result of the depth of the system error SIL, although this sometimes happens (SIL — South Iceland Lowland — a system designed to warn of earthquakes in the area of South Iceland —approx. Translator). The second earthquake occurred at 10:13 UT. Its magnitude was 1.6 on the Richter scale and the depth of 1.6 km. With the volcano could expect anything to happen, for them to follow, even if the eruption is not expected.
Volcano Baytoushan (Baekdu), a dormant volcano in North Korea, which is not erupted since 1903, is showing signs of increased activity, especially after the earthquake of 9 points in the Tohoku and tsunami hit March 11, 2011. 19 dormant volcanoes in Japan also show signs of increased activity. In the Philippines, reported the three volcanoes, whose activity is increased, and in New Zealand, said that the volcano Ruapehu increased emissions of gases, and increased temperature of the crater lake. Three mud volcano erupted in Azerbaijan after the earthquake in Japan that occurred on March 11. Under the network of ancient volcanoes of Iceland also continuing aftershocks. All or one big coincidence, or we enter into the next stage of the crisis geological changes on the Earth.
