Satellite data by KVERT showed an ash plume extended about 1400 km to the east from the volcano, and a thermal anomaly over the volcano. BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 2882 m (9453 ft) Aviation Colour Code is ORANGE An extrusive-effusive eruption of the volcano continues, a strong fumarolic activity, an incandescence of the lava dome, and hot avalanches accompanies this process. Satellite data by KVERT showed a thermal anomaly over the volcano. EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 1156 m (3792 ft) Aviation Colour Code is ORANGE A moderate eruptive activity of the volcano continues.
