A high-level eruption at Sheveluch volcano in Kamchatka, Russia, at 07:25 UTC on July 5, 2026, sent volcanic ash as high as 12.2 km (40 000 feet) and prompted authorities to raise the Aviation Color Code to Red. Satellite observations later confirmed continuing ash emissions drifting southwest.
Mutnovsky volcano in southern Kamchatka, Russia, produced an ash explosion at 20:19 UTC on July 1, 2026 (08:19 LT on July 2), marking its first documented eruption since July 3, 2013. KVERT reported that the approximately 3-minute event generated an ash plume up to 3.5 km (11 500 feet) above sea level, extending about 10 km (6 miles) west of the volcano.
Sheveluch volcano on Russia’s Kamchatka Peninsula produced an explosive eruption at 08:00 UTC on June 6, 2026, sending ash to about 12 km (39 400 feet) above sea level and triggering a Red aviation color code.
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.
