Danger of explosive eruptions

Danger of explosive eruptionsUnusually weak Cleveland volcano in the Aleutian Islands off Alaska, USA, may be a prelude to a large-scale natural disaster. This was reported by Reuters, with reference to the Alaskan Volcano Observatory (Alaska Volcano Observatory).
Cleveland, the peak height of about 1700 meters, 1.5 thousand km south of the capital of Alaska, Anchorage, spewing lava from the crater mid-July. The volume of lava spewing relatively small, but satellite images show that in the crater of the volcano are rising lava. "We fear an explosive eruption," — said Steve McNutt (Steve McNutt) at the University of Alaska-Fairbanks (University of Alaska Fairbanks), chief researcher at the volcano observatory.
Explosive eruption threatens to release to the atmosphere of a large amount of ash, which, in turn, may lead to local climate change and the suspension of air traffic.
In other words, it can implement the same scenario that occurred during the eruption of the Icelandic volcano Eyjafjallajökull last spring. Recall, this volcano, whose name we can not pronounce, erupted twice on March 20 and April 14, 2010, with the second eruption was 10-20 times more powerful than the first. The resulting cloud of volcanic ash is not only during a total stop flights over Europe, but also brought a lot of problems on the ground, for example, Icelandic farmers had to quickly build a shelter for their animals, the health and even lives are threatened by the same ashes.
Earlier this year, U.S. experts fear that this story is repeated on a larger scale, in the case of waking a sleeping giant volcano beneath Yellowstone National Park in Wyoming. However, this is now, fortunately, did not happen. But now North America, as we see, face Cleveland.
