Continuous ash emissions at Sheveluch volcano reach 10 100 m (33 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at 10 100 m (33 000 feet) above sea level at 22:50 UTC on March 22, 2026. The advisory was issued by the Anchorage VAAC at 22:50 UTC.

Satellite imagery from Himawari confirmed continuous ash emissions at a maximum observed altitude of 10 100 m (33 000 feet). The ash cloud was moving east at a speed of 93 km/h (58 mph). Ash was partially obscured by meteorological clouds. No Aviation Color Code was stated in this advisory.

According to the Smithsonian/USGS Weekly Volcanic Activity Report, Sheveluch has continued eruptive activity at the lava domes on the north crater floor of Young Sheveluch. Explosions during March 11–12 generated ash plumes that rose up to 8 000 m (19 700 feet) above sea level and drifted 2 410 km (1 500 miles) east and northeast. On March 16, explosions produced ash plumes up to 11 000 m (36 100 feet), which drifted over 1 800 km (1 100 miles) east. The Aviation Color Code remains at Orange.

Sheveluch is a large stratovolcano situated in the northern part of the Kamchatka Peninsula. The volcano is known for frequent explosive activity, dome growth, and large ash plumes. Key hazards include ashfall, pyroclastic flows, and lava domes collapse. Communities such as Klyuchi, located about 50 km (31 miles) south-southwest, could be affected during significant eruptive events.
