Petropavlovsk-Kamchatsky, Russia – August 4, 2025 – A long-dormant volcano on Russia’s Kamchatka Peninsula has erupted for the first time in centuries, just days after a powerful earthquake struck the region. The Krasheninnikov volcano, which scientists estimate has been dormant for as long as 600 years, began erupting overnight on Sunday, sending a massive ash plume an estimated 6,000 meters (3.7 miles) into the sky.
The Kamchatka Volcanic Eruption Response Team (KVERT) has noted that the ash plume is drifting eastward over the Pacific Ocean, away from inhabited localities, and no ashfall has been recorded in populated areas. The eruption, which was accompanied by a magnitude 7.0 earthquake, has been assigned an “orange” aviation code, indicating a heightened risk to aircraft in the area.
This event closely follows another significant eruption on Wednesday, July 30, from Klyuchevskoy, one of Eurasia’s tallest and most active volcanoes. That eruption also spewed lava and ash plumes, prompting similar aviation warnings.
Scientists are investigating a potential link between the volcanic activity and a powerful magnitude 8.8 earthquake that struck off the coast of the Kamchatka Peninsula last week. The region, located on the seismically volatile Pacific Ring of Fire, is home to a high concentration of active volcanoes. Authorities are closely monitoring the situation and have advised residents and travelers to avoid the active zones.
