Explosive activity at Sheveluch volcano, Kamchatka, Russia, sent volcanic ash to 11 km (36 000 feet) above sea level on March 29, 2026, prompting authorities to raise the Aviation Color Code to Red.
Explosive activity at Sheveluch volcano on the Kamchatka Peninsula, Russia, produced a volcanic ash plume rising to approximately 10.4 km (34 000 feet) altitude at 11:20 UTC on March 16, 2026, drifting east across the North Pacific. Satellite imagery from Himawari-9 detected the ash cloud moving east at around 110 km/h (70 mph). The Aviation Color Code remains at Orange.
An explosive pulse at Sheveluch volcano, Kamchatka, Russia, around 04:54 UTC on January 28, 2026, sent ash to about 9 km (30 000 feet) above sea level, with a plume drifting west over the Kamchatka Peninsula. Tokyo VAAC advisories through 12:00 UTC indicate continuing ash, with tops between 6 km (19 700 feet) and 7 km (23 000 feet) after the initial 9 km (30 000 feet) eruption.
A powerful explosive eruption took place at Bezymianny volcano in Kamchatka, Russia, on November 26, 2025, with ash reaching 11.4 km (37 400 feet) a.s.l., as of 04:00 UTC. The Aviation Color Code was raised to Red due to ongoing explosions that could affect regional and international flights.
Kronotsky volcano in Kamchatka, Russia, erupted at 03:50 UTC (15:50 LT) on October 4, 2025, ending a century of dormancy. The Kamchatka Volcanic Eruption Response Team (KVERT) reported an explosive eruption with an ash column reaching 9.2 km (30 180 feet) above sea level. Aviation Color Code was raised to Red. KVERT warns that additional ash emissions rising up to 15 km (49 200 feet) remain possible.
Eruptive activity at Klyuchevskoy volcano intensified after M 8.8 earthquake on July 29, 2025, with a large lava flow descending the WSW flank, continuous lava fountaining, and a significant ash plume. Based on volcanic tremor data and current eruptive behavior, a paroxysmal eruption is considered likely within the next 72 hours.
The Krasheninnikov volcano erupted for the first time in 600 year on August 3, 2025, sending an ash plume 6 km (19 700 feet) into the sky. Scientists suggest that the eruption might have been linked to the M8.8 earthquake that struck the Kamchatka peninsula on July 30.
A strong eruption began at Sheveluch volcano, Kamchatka, Russia, around 18:00 UTC on May 16, 2025, producing a plume of ash and sulfur dioxide up to 12.2 km (40 000 feet) above sea level, according to the Tokyo Volcanic Ash Advisory Center (VAAC). The Aviation Color Code remains at Orange.
A strong explosive eruption took place at the Bezymianny volcano in Kamchatka, Russia, on April 23, 2025, sending an ash plume 11 km (36 000 feet) above sea level. As a result, the Aviation Color Code was raised to Red.
An extrusive-effusive eruption at Bezymianny volcano in Kamchatka, Russia, intensified on April 11, 2025, producing pyroclastic flows on the eastern slopes and ash plumes reaching 3–4 km (9 800–13 100 feet) above sea level. Current data suggests the volcano is preparing for a strong explosive eruption.
