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, sometimes explosions, and hot avalanches accompanies this process. Satellite data by KVERT showed an ash plume extended up to 62 km to the east from the volcano on March 11, and a thermal anomaly over the volcano all week. 
Danger Prognosis for Aviation: An 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.
