Ash cloud from Sheveluch volcano reaches 10 100 m (33 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch volcano in Russia was observed at 10 100 m (33 000 feet) above sea level at 05:35 UTC on March 23, 2026. The advisory was issued by the Anchorage VAAC at 05:35 UTC.

Satellite imagery from HIMAWARI/GOES confirmed the presence of a persistent ash cloud extending from the surface up to flight level 330, which is equivalent to 10 100 m (33 000 feet). The ash cloud was moving southeast at approximately 83 km/h (52 mph). No Aviation Color Code was stated in this advisory.

According to the Smithsonian / USGS Weekly Volcanic Activity Report, Sheveluch’s eruptive activity continued between March 12 and March 18, 2026. Explosions during March 11–12 generated ash plumes up to 8 000 m (19 700 feet) above sea level, drifting 2 410 km (1 500 miles) east and northeast. Ash plumes on March 16 reached up to 11 000 m (36 100 feet) above sea level and drifted more than 1 800 km (1 100 miles) east.

Sheveluch is a large, active stratovolcano located on the Kamchatka Peninsula. It poses hazards such as ashfall, pyroclastic flows, and lava domes collapse. Settlements at risk include Klyuchi, situated approximately 50 km (31 miles) south-southwest of the volcano.
