The Krasheninnikov volcano on Russia’s Kamchatka Peninsula erupted for the first time in approximately 600 years. The eruption occurred overnight on August 3, 2025, at about 06:00 local time. The volcano stands at 1,856 meters elevation, located within the Kronotsky Nature Reserve, roughly 200 kilometers from Petropavlovsk Kamchatsky. Ash rose in a column reaching up to 5–6 kilometers above sea level. The ash cloud drifted eastward toward the Pacific Ocean, over uninhabited terrain, with no known threat to populated areas. The aviation hazard code was set to orange, prompting warnings for low flying aircraft. The eruption followed a magnitude 8.8 earthquake off Russia’s Far East on July 30, 2025, which triggered tsunami alerts across the Pacific. Scientists and Russian emergency officials believe that the magnitude 8.8 earthquake and several aftershocks including one of magnitude 6.7–6.8 may have triggered the volcanic eruption. Krasheninnikov volcano’s last known lava activity occurre...
