Sheveluch Volcano. Monitoring
Aviation Color Code:
ORANGE 
Current State: A growth of the lava dome continues, a strong fumarole activity, an incandescence of the lava dome, explosions, and hot avalanches accompanies this process. Video data by KVERT showed an ash plume associated with hot avalanches collapses is extending for 10 km to the north-east of the volcano. 
Danger Prognosis for Aviation: The extrusive eruption of the volcano continues. Ash explosions up to 10-15 km (32,800-49,200 ft) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.
