Continuous ash emission at Sheveluch volcano reaches 9 100 m (30 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch volcano in Russia was observed at 9 100 m (30 000 feet) above sea level at 11:51 UTC on April 6, 2026. The advisory was issued by the Anchorage VAAC at 11:51 UTC.

The ash cloud was observed between the surface and FL300 (9 100 m, 30 000 feet) and identified in Himawari satellite imagery. The volcanic ash was moving north at approximately 56 km/h (35 mph). No Aviation Color Code was stated in this advisory. Some portions of the ash cloud may be obscured by meteorological clouds.

According to the most recent Smithsonian/USGS Weekly Volcanic Activity Report, Sheveluch has exhibited ongoing eruptive activity with explosions generating ash plumes that reached as high as 11 600 m (38 100 feet) above sea level during March 19–25, 2026, and a new dome lobe continued to grow along the north part of the main lava dome.

Sheveluch is one of the largest and most active stratovolcanoes on Russia’s Kamchatka Peninsula. Known hazards include explosive eruptions, extensive ashfall, pyroclastic flows, and lava domes, which can threaten communities located 50 km (31 miles) or more from the volcano, including the town of Klyuchi to the south. Aviation routes in the region are frequently subject to hazard from high ash plumes.
