Continuous volcanic ash emissions from Sheveluch reach 10 100 m (33 000 feet) a.s.l., Kamchatka Peninsula, Russia

Volcanic ash from Sheveluch volcano in Russia’s Kamchatka Peninsula was observed at 10 100 m (33 000 feet) above sea level at 16:50 UTC on March 22, 2026. The advisory was issued by the Anchorage VAAC at 16:50 UTC on March 22, 2026.

Continuous volcanic ash was observed in satellite imagery from the Himawari satellite. The ash cloud extended up to 10 100 m (33 000 feet) above sea level (corresponding to FL330). Ash was partially obscured by meteorological cloud. No Aviation Color Code was stated in this advisory. Forecasts indicated continued ash dispersion at the same altitude over the following 6, 12, and 18 hours.

According to the Smithsonian / USGS Weekly Volcanic Activity Report, Sheveluch was experiencing ongoing activity between March 12 and March 18, 2026. During this period, thermal anomalies were consistently detected in satellite imagery. Explosions during March 11–12 generated ash plumes reaching as high as 8 000 m (19 700 feet) and drifting 2 410 km (1 500 miles) east and northeast. On March 16, ash plumes rose up to 11 000 m (36 100 feet) and drifted more than 1 800 km (1 100 miles) east. The Aviation Color Code remained at Orange.

Sheveluch is a large and active stratovolcano in the northern part of the Kamchatka Peninsula. The volcano is known for frequent explosive eruptions, producing ashfall, pyroclastic flows, and lava domes. Primary hazards include widespread ashfall and pyroclastic flows, with aviation and local settlements at risk. The nearest towns, such as Klyuchi, are situated approximately 50 km (31 miles) away.
