The Krasheninnikov volcano on Russia's Kamchatka Peninsula erupted on August 3, 2025, marking its first eruption in over 450 years, with some sources citing up to 600 years of dormancy. The eruption followed a powerful magnitude 8.8 earthquake that struck the region on July 30, 2025, which is believed to have triggered the volcanic activity. The eruption produced an ash plume reaching heights of 5,000 to 6,000 meters (5 to 6 kilometers). Following this event, seismic and volcanic activity in Kamchatka intensified, with seven volcanoes currently showing signs of activity and the peninsula reportedly shifting almost two meters to the southeast. The earthquake also generated tsunami warnings across the Pacific and was observed from space by NASA satellites. Authorities and scientists have warned of potential further seismic and volcanic episodes in the area.
