Volcanic ash from Sheveluch volcano observed at 8 200 m (27 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at 8 200 m (27 000 feet) above sea level at 12:00 UTC on April 9, 2026. The advisory was issued by Anchorage VAAC at 12:00 UTC.

The ash cloud was identified in satellite imagery from the Himawari and GOES satellites. The observed ash altitude was surface to 8 200 m (27 000 feet), with some volcanic ash obscured by meteorological cloud cover. No Aviation Color Code was stated in this advisory.

According to the Smithsonian / USGS Weekly Volcanic Activity Report for March 26 to April 1, 2026, Sheveluch displayed continuing eruptive activity. Explosions on March 27, March 29, and March 31 generated ash plumes rising to 10 600–12 000 m (34 780–39 370 feet) above sea level. A new dome lobe continued to grow, and thermal anomalies were detected daily. The Aviation Color Code remained at Orange.

Sheveluch is one of Kamchatka’s largest and most active stratovolcanoes, presenting hazards such as ash fall, pyroclastic flows, and lava domes. The nearby community of Klyuchi, approximately 50 km (31 miles) to the south-southwest, may be at risk from ashfall and other volcanic hazards during periods of significant activity.
