Continuous ash emissions from Sheveluch volcano reach 9 100 m (30 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at 9 100 m (30 000 feet) above sea level at 23:50 UTC on April 6, 2026. The advisory was issued by the Anchorage VAAC at 23:50 UTC.

According to the advisory, volcanic ash was continuously detected in satellite imagery up to an altitude of 9 100 m (30 000 feet). The ash cloud was moving north at about 56 km/h (35 mph). The advisory did not state an Aviation Color Code. Forecasts indicated the ash cloud could persist at similar altitudes over the next 12 hours, with signals weakening over time.

The Smithsonian / USGS Weekly Volcanic Activity Report for March 19–25, 2026, notes that Sheveluch exhibited frequent lava dome growth and produced explosions that sent ash plumes to 9 500–11 600 m (31 200–38 100 feet) with ash drifting up to 2 410 km (1 500 miles) east and northeast. The Aviation Color Code for Sheveluch remained at Orange.

Sheveluch is a large stratovolcano located on the Kamchatka Peninsula. It is one of the most active volcanoes in the region, with a history of explosive eruptions, lava domes, and pyroclastic flows. Nearby settlements, including the town of Klyuchi, located about 50 km (31 miles) to the south, may be at risk from ashfall and other volcanic hazards.
