Continuous ash emissions from Sheveluch volcano observed at 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 05:50 UTC on April 7, 2026. The advisory was issued by the Anchorage Volcanic Ash Advisory Center (VAAC) at 05:50 UTC.

Satellite data from Himawari and GOES confirmed continuous volcanic ash emissions at Sheveluch. The observed ash cloud height was reported at flight level FL300, equivalent to 9 100 m (30 000 feet) above sea level. No Aviation Color Code was stated in this advisory. The VAAC noted that the volcanic ash signal was weakening.

According to the Smithsonian / USGS Weekly Volcanic Activity Report for March 19–25, 2026, Sheveluch volcano continued eruptive activity at the active lava domes along the northern crater floor of Young Sheveluch. Explosions during March 19–22 generated ash plumes rising 9 500–11 600 m (31 200–38 100 feet) above sea level and drifting significant distances. The Aviation Color Code remained at Orange during this period.

Sheveluch is a large, active stratovolcano located on the Kamchatka Peninsula. It is known for frequent explosive eruptions, high lava domes, and associated hazards such as widespread ashfall, pyroclastic flows, and lahars. Nearby settlements at risk include the communities of Klyuchi, located approximately 50 km (31 miles) south-southwest of the volcano.
