Residual volcanic ash from Sheveluch volcano detected between 4 300 m (14 000 feet) and 9 800 m (32 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at altitudes between 4 300 m (14 000 feet) and 9 800 m (32 000 feet) above sea level at 20:24 UTC on April 3, 2026. The advisory was issued by the Anchorage VAAC at 20:24 UTC on April 3, 2026.

According to the VAAC advisory, residual volcanic ash was detected on satellite imagery and reported in pilot reports between flight levels FL140 (4 300 m / 14 000 feet) and FL320 (9 800 m / 32 000 feet). No Aviation Color Code was stated in this advisory. The advisory tracks the ash cloud’s forecast movement for the next 12 hours.

According to the Smithsonian/USGS Weekly Volcanic Activity Report, Sheveluch experienced continuing eruptive activity during March 19-25, 2026. Explosions during this period generated ash plumes that rose 9 500–11 600 m (31 200–38 100 feet) above sea level and drifted up to 2 410 km (1 500 miles) east and northeast. The Aviation Color Code remained at Orange.

Sheveluch is a large stratovolcano located in the northern part of the Kamchatka Peninsula. It is one of the most active volcanoes in the region, with hazards including ashfall, pyroclastic flows, and lava dome growth and collapse. Local settlements such as Klyuchi, located about 50 km (31 miles) southwest, may be at risk during major eruptive episodes.
