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 17:30 UTC on March 31, 2026. The advisory was issued by the Tokyo VAAC at 18:00 UTC on March 31, 2026.

The volcanic ash cloud was observed between the surface and FL290, which corresponds to a maximum altitude of 8 800 m (29 000 feet) above sea level. Ash was continuously observed in satellite imagery from Himawari-9. The ash cloud was reported to be moving east at a speed of 28 km/h (17 mph). No Aviation Color Code was stated in this advisory.

According to the Smithsonian / USGS Weekly Volcanic Activity Report, Sheveluch experienced ongoing eruptive activity from 11 to 18 March 2026. Explosions generated ash plumes rising as high as 11 000 m (36 100 feet) above sea level, with ash drifting significant distances. The Aviation Color Code remained at Orange.

Sheveluch is a large stratovolcano in Kamchatka, Russia, and one of the region’s most active. Hazards include large ash plumes, pyroclastic flows, and lahars, which can affect nearby settlements such as Klyuchi, located about 50 km (31 miles) south of the volcano.
