Russia’s Shivulech volcano extremely active, threatens eruption, scientists say
Subject: Geography
Context-
- The Shiveluch volcano on the Kamchatka Peninsula in the Russian Far East has become extremely active, threatening a powerful eruption, the Kamchatka Volcanic Eruption Response Team said.
- A growth of the lava dome continues, a strong fumaroles activity, an incandescence of the lava dome, explosions, and hot avalanches accompanies this process.
- Ash explosions up to 10-15 kilometres (9.32 miles) could occur at any time.
- Ongoing activity could affect international and low-flying aircraft.
- The volcano last most powerful eruption took place in 2007
About-
- Shiveluch is the northernmost active volcano in Kamchatka Krai, Russia.
- It and Karymsky are Kamchatka’s largest, most active and most continuously erupting volcanoes.
- The summit reaches 3,283 metres (10,771 feet)
- An estimated 60 substantial eruptions in the past 10,000 years.
- On February 27, 2015 Shiveluch erupted shooting ash into the atmosphere about 30,000 feet crossing the Bering Sea and into Alaska.
- The Kamchatka Krai is a part of Pacific ring of fire.
Characteristics-
- Shiveluch belongs to the Kliuchevskaya volcano group.
- There are three elements of the volcano:
- the stratovolcano Old Shiveluch;
- an ancient caldera, and
- the active Young Shiveluch with an elevation of about 2,800 metres (9,186 ft).
- Shiveluch is one of Kamchatka’s largest and most active volcanic structures.
- It is a stratovolcano composed of alternating layers of solidified ash, hardened lava and volcanic rocks.
- The nearest settlement from the volcano is Klyuchi, situated 50 km from the mountain.
- The settlement is small enough to evacuate rapidly in case of a major eruption.
