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 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 began at Russia’s Sheveluch volcano at 09:20 UTC on November 7, 2024. The eruption produced significant volcanic ash emissions, with an ash plume reaching altitudes of 11 km (36 000 feet) above sea level. The ash cloud is drifting east-northeast, posing a threat to aviation.
A new explosive eruption began at the “300 years of RAS” lava dome at Sheveluch volcano, Kamchatka, Russia at 11:45 UTC on August 17, 2024.
Ash clouds produced by the major eruption of Russia’s Sheveluch volcano led to the cancellation of scores of flights in Alaska. The ash clouds drifted across the International Date Line into Alaska airspace, causing safety concerns for airlines over the next couple of days. As a precautionary measure, Alaska Airlines canceled 45 flights to and from Alaska and within the state. Other airlines also had to cancel or delay their flights.
A powerful explosive eruption took place at Russia’s Sheveluch volcano at 13:10 UTC on April 10, 2023. As a result, KVERT raised the Aviation Color Code from Orange to Red. Very heavy ashfall — the strongest in 60 years — was reported in Klyuchi and other nearby cities and villages.
The extrusive eruption at Sheveluch volcano in Russia continues, with the growth of the lava dome and strong fumarole activity observed. Incandescence of the lava dome, explosions, and hot avalanches have also been reported in conjunction with this process.
