Krasheninnikov Volcano Latest News

The eruption of the Krasheninnikov volcano was recently recorded for the first time.

About Krasheninnikov Volcano

• It is an active complex volcano located in the Eastern Kamchatka Peninsula, Russia.
  • The Kamchatka Peninsula lies along the Pacific “Ring of Fire.”
  • There are 114 volcanoes on the Kamchatka Peninsula that have erupted during the Holocene Epoch (approximately 12,000 years ago to the present).
• Krasheninnikov is a stratovolcano and reaches a height of 1,886 meters.  
• The volcano is located in a collapsed caldera, which formed after a catastrophic eruption which produced 50 cubic km of dacitic pumice 39,600 years ago.
• It is made up of two eruptive cones in a 9 km wide caldera.  
• The southern cone of Krasheninnikov contains a crater 800 m wide and 140 m deep.
• Its last eruption took place about 400 or 600 years ago.
• 2025 Eruption: Krasheninnikov volcano erupted on 2 August 2025, three days after a nearby magnitude 8.8 earthquake. Ash emissions reached an altitude of 20,000 ft.

What is a Stratovolcano?

• It is a tall, steep, and cone-shaped type of volcano.
• Unlike flat shield volcanoes, they have higher peaks.
• They are typically found above subduction zones, and they are often part of large volcanically active regions, such as the Ring of Fire that frames much of the Pacific Ocean.
• Strato Volcanoes comprise the largest percentage (~60%) of the Earth’s individual volcanoes, and most are characterized by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt.
• These more viscous lavas allow gas pressures to build up to high levels. Therefore, these volcanoes often suffer explosive eruptions. 
• They are usually about half-half lava and pyroclastic material, and the layering of these products gives them their other common name of composite volcanoes.
• At the peak, stratovolcanoes usually have a small crater. The crater may be filled with water or ice, or it may contain a volcanic dome during a period of relative inactivity.
