stratovolcano
Kamchatka, 55.98°N / 160.59°E 
Summit height: 2882 m / 9,455 ft
Current status: erupting (4 out of 5)
Last update: 23 Nov 2025 (elevated activity, hot rock avalanches from lava dome)

Bezymianny ("unnamed") was considered extinct until it erupted violently in 1955-56, after a slumber of probably 1000 years. It is one of the most active volcanoes in Kamchatka. The eruption followed a massive flank failure (similar to Mt. St. Helens eruption in 1980) which removed a 0.5 sq km sector of the volcano.

Background
The present-day Bezymianny volcano, lying next to its massive sisters Kamen and Kliuchevskoi, is a young and relatively small volcano only about 4700 years old. It was formed on top of an older volcano built between about 11,000-7000 years ago. 3 periods of intensified activity have been recognized in the geologic history during the past 3000 years. The present-day activity started with the eruption in 1955-56 after a 1000 year interval of repose. At the beginning of the eruption, the summit and a large sector of its flank failed and resulted in a catastrophic landslide followed by a powerful blast. The event left a large horseshoe-shaped crater. Since then, the volcano has been one of Kamchatka's most active. A new lava dome has been growing inside the 1956 crater, frequently producing explosive activity and pyroclastic flows. As of 2011, the lava dome has already largely filled the 1956 crater.Bezymianny Volcano Photos

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

Bezymianny Volcano FAQ
+When was the last eruption of Bezymianny volcano?
The last confirmed eruption of Bezymianny occurred during 2022 - 2024.
+How often does Bezymianny volcano erupt?
Bezymianny volcano erupts almost every year. Since its first historically documented eruption 1955, Bezymianny has often been near-continuously active. The Global Volcanism Project counts 55 historic eruptions until now, spanning a total of 67 out of 70 years. In other words, Bezymianny is active roughly every one in 1 years on average. This value is likely an underestimate, because the known history of eruption might not contain all eruptions, especially further back in time. The last eruption of Bezymianny
+How active is Bezymianny volcano at present?
Bezymianny volcano is extremely active: Since 1900, it has been frequently active, showing eruptive activity during 67 years out of 126 as of now. The last eruption was from 2022 until 2024 and ended 15 months ago.
+When was the largest eruption of Bezymianny volcano?
The largest eruption of Bezymianny volcano in historic times occurred during 1955 - 1957. It ranks as a plinian eruption with a magnitude 5 on the VEI (Volcanic Explosivity Index) scale. Eruption of this size are often catastrophic on a regional scale.
