Continuous ash cloud from Sheveluch volcano reaches 8 800 m (29 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch volcano in Russia was observed at 8 800 m (29 000 feet) above sea level at 23:20 UTC on March 31, 2026. The advisory was issued by Tokyo VAAC at 00:00 UTC on April 1, 2026.

Satellite data, including Himawari-9, indicated continuous volcanic ash present in imagery. The ash cloud was observed at an altitude up to 8 800 m (29 000 feet) and was moving east at approximately 28 km/h (17 mph). No Aviation Color Code was stated in this advisory.

The most recent Smithsonian/USGS Weekly Volcanic Activity Report (for March 12–18, 2026) confirms that Sheveluch volcano continues to exhibit eruptive activity with frequent explosions and ash plumes reaching up to 11 000 m (36 100 feet), and drifting for considerable distances. Daily thermal anomalies and eruptive activity have been reported at the site.

Sheveluch is a large, active stratovolcano in Russia’s Kamchatka Peninsula. It presents multiple volcanic hazards including widespread ashfall, pyroclastic flows, and lava domes. The town of Klyuchi, situated about 50 km (31 miles) south, is among the settlements at risk from future activity. Volcanic ash from Sheveluch can disrupt air traffic and impact regional populations and infrastructure.
