Eruption occurred in Russia’s Bezymianny volcano after 69 years

The Bezymianny volcano located on Russia’s Kamchatka Peninsula has become active again after the year 1956. The Russian volcano sent an ash cloud up to a height of 32,800 feet (10 kilometers) in an eruption.

• An eruption in 1956 caused most of the Bezymianny volcano in Russia’s Kamchatka to collapse, but since then continuous eruptions — including a major event in November — have now made it almost fully active again.
• The Russian volcano sent an ash cloud up to a height of 32,800 feet (10 kilometers) in an eruption, bringing the mountain close to its original height.

About Bezymianny volcano

• The Bezymianny volcano is a dramatic, cone-shaped stratovolcano on the Kamchatka Peninsula in the Russian Far East.
• It erupted in 1956, but a 2020 study found that it has almost grown back, and the eruptions that produced ash plumes on November 26 are the reason for this.
• That study found that the mountain will regain its pre-collapse height before falling again between 2030 and 2035.
• Seven decades ago, Bezymianny was at least 10,213 feet (3,113 meters) above sea level. Then, on March 30, 1956, a major eruption blew out the volcano’s flank, causing the summit to collapse and turning the cone-shaped mountain into a horseshoe-shaped rock amphitheater.

Kamchatka Peninsula:

• It is located on the Pacific Ring of Fire. To its west is the Sea of Okhotsk and to its east are the Pacific Ocean and the Bering Sea.
• This peninsula is located at the junction of the Pacific and North American tectonic plates, making it an extremely active seismic zone.
• There are two major mountain ranges here — Sredinny and Vostochny. The major river of this region is the Kamchatka River, which is its main waterway.
• Volcanic and geothermal activity:  The Kamchatka Peninsula is home to the Volcanoes of Kamchatka, which are UNESCO World Heritage Sites.
• There are more than 150 volcanoes here, of which 29 are active. Klyuchevskoy is the highest and most active volcano in this region.
• The Kuril Islands stretch from Kamchatka to Japan and are a disputed region between Russia and Japan.

Major volcanoes of Russia

• Russia’s main volcanoes are mostly on the Kamchatka Peninsula and the Kuril Islands, which are part of the Pacific “Ring of Fire”. Major active volcanoes include Klyuchevskaya Sopka (the highest in Eurasia), Shiveluch, Karymsky, and Avachinsky. There are more than 300 volcanoes in this region, of which about 29 are active.

“Ring of Fire”

• A 40,000 km long horseshoe-shaped region located along the edges of the Pacific Ocean, which is famous for its high volcanic and seismic activity. This region is the center of about 75% of the world’s active volcanoes and 90% of earthquakes, which are formed due to the movement (Subduction) of tectonic plates.
• Tectonic plates: It is located along the boundaries of the Pacific, Philippine, Juan de Fuca, Cocos, Nazca, and Indo-Australian plates.
• Important countries: Countries such as Chile, Peru, Mexico, United States of America (western coast), Canada, Russia, Japan, Philippines, Indonesia, and New Zealand come under it.
