In Kamchatka, Sheveluch continues its explosive-extrusive activity. Ash explosions produced a cloud of ash at 9,500-10,000 meters on November 11 drifting towards ESE for 55 km.

Thermal anomalies are reported by Mirova, between 3 and 49 MW on 11 and 12 November.

The aviation code is orange, due to a possible continuation of activity, characterized by ash plumes between 10 and 15 km.
