Continuous volcanic ash observed at Sheveluch volcano reaches 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 02:20 UTC on March 28, 2026. The advisory was issued by the Tokyo VAAC at 03:00 UTC on March 28, 2026.

According to the VAAC advisory, continuous volcanic ash was observed in satellite imagery, with the ash plume at an altitude of 10 100 m (33 000 feet). The ash cloud was noted to be moving south at a speed of 37 km/h (23 mph). Some portions of the ash were obscured by meteorological clouds. The current Aviation Color Code was not stated in this advisory.

The Smithsonian / USGS Weekly Volcanic Activity Report for March 11–18, 2026, notes that Sheveluch volcano has maintained active lava domes along the northern crater floor of Young Sheveluch. Explosions during March 11–12 generated ash plumes up to 8 000 m (19 700 feet) above sea level, while events on March 16 produced ash plumes up to 11 000 m (36 100 feet) above sea level, drifting for over 1 800 km (1 100 miles) eastward. The Aviation Color Code remained at Orange during that period.

Sheveluch is a large stratovolcano located in the Kamchatka Peninsula, Russia. Known hazards include strong ashfall, pyroclastic flows, and dome collapse events. The volcano is situated in a sparsely populated area, with the closest settlements being the town of Klyuchi, approximately 50 km (31 miles) south-southwest, which could be affected by significant eruptive events.
