Alaska volcano erupts


12.08.11.Na Chuginadak desert island, which administratively belongs to the U.S. state of Alaska, began erupting volcano Cleveland.

This volcano is one of the most active in the world, reports the Associated Press.

Eruption of Cleveland looks like a slow outpouring of magma, forming a lava dome, and not as vigorous eruption with explosions and ash emissions.

While lava remains inside the summit crater. But when the lava dome grow so that the lava comes out of the crater, can begin explosions, accompanied by a column of ash emissions, that is, the situation becomes much more dangerous.

Recent monitoring of several volcanoes show that lava dome can grow from a few weeks to months. Volcanologists are going to observe the volcano by analyzing satellite images and photos taken with the flying aircraft. Organize a special flight to the volcano is not planned.

Recall that on August 3 at Hawaii eruption is one of the most active volcanoes in the world — the flat shield-shaped Mount Kilauea (Kilauea), the height of which is 1247 m Scientists admit that in the near future may come to life the next "neighbors" Kilauea — volcanoes located in the National Park "Hawaii Volcanoes."

And in the meantime, Kamchatka volcano Shiveluch activated, he threw the ashes with gas at a height of 7 meters above sea level. With the volcano go hot avalanches, and its crater is observed thermal anomaly. Orange code for aircraft assigned risk Shiveluch and spewing Karymskii. Does not cease until one more Kamchatka volcano — Kizimen.
