Continuous ash emissions at Sheveluch volcano reach 8 800 m (29 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at 8 800 m (29 000 feet) above sea level at 11:20 UTC on April 1, 2026. The advisory was issued by the Tokyo VAAC at 12:00 UTC.

The ash cloud was continuously observed in Himawari-9 satellite imagery, reaching from the surface up to flight level FL290, corresponding to 8 800 m (29 000 feet). The ash cloud was moving east at approximately 37 km/h (23 mph). Some parts of the ash plume were obscured by meteorological clouds. No Aviation Color Code was stated in this advisory.

According to the Smithsonian’s Global Volcanism Program, Sheveluch has experienced continuing eruptive activity, with ash plumes on March 11-12, 2026 reaching as high as 8 000 m (19 700 feet) above sea level and drifting considerable distances east and northeast. Explosions on March 16, 2026 produced ash plumes up to 11 000 m (36 100 feet) above sea level, with widespread ash transport noted.

Sheveluch is a large stratovolcano located in the northern part of Russia’s Kamchatka Peninsula. It is one of the most active volcanoes in the Kamchatka region, characterized by explosive eruptions, ashfall, pyroclastic flows, and lava dome growth. Hazards from Sheveluch include ashfall over broad areas, pyroclastic flows, and disruption to aviation. The nearest settlements, including the town of Klyuchi located about 50 km (31 miles) southwest, can be affected by ashfall events.
