Residual volcanic ash from Sheveluch volcano at 8 200 m (27 000 feet) a.s.l., Kamchatka Peninsula, Russia

Volcanic ash from Sheveluch volcano in Russia’s Kamchatka Peninsula was observed at 8 200 m (27 000 feet) above sea level at 06:00 UTC on April 9, 2026. The advisory was issued by VAAC Anchorage at 06:00 UTC.

The ash cloud was detected within the surface to FL270 flight level band, which corresponds to an altitude of 8 200 m (27 000 feet). Some of the volcanic ash was obscured by meteorological clouds. Satellite imagery from Himawari was used as the information source. No Aviation Color Code was stated in this advisory.

According to the Smithsonian / USGS Weekly Volcanic Activity Report for March 26–April 1, 2026, eruptive activity continued at Sheveluch. A new dome lobe continued to grow along the northern part of the main lava dome. Explosions on March 27, 29, and 31 generated ash plumes reaching 10 600–12 000 m (34 800–39 400 feet) above sea level. The Aviation Color Code remained at Orange.

Sheveluch is a large stratovolcano located in the northern part of the Kamchatka Peninsula. It is known for frequent explosive eruptions that can generate high-altitude ash clouds, lava dome growth, and pyroclastic flows. The nearest settlements include the village of Klyuchi, located approximately 50 km (31 miles) southwest, which can be affected by ashfall during eruptive episodes.
