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.
