Activity of the volcano continues. Ash explosions up to 26,200-32,800 ft (8-10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.


Fumarole activity of Klyuchevskoy volcano on 09 March, 2017.

According to visual and satellite data, ash bursts up to 5.5 km a.s.l. were observed on 08 March; ash plume drifted for about 20 km to the north-west from the volcano. Satellite data by KVERT showed a thermal anomaly over the volcano on 02-03, 05 and 08-09 March; the volcano was obscured by clouds in the other days of week.

As in previous days, seismic recording of the volcanic tremor remains similar with fluctuating mean amplitude. This morning it was possible to observe the activity which was accompanied by a low intermittent emission of gases and aerosols which were dispersed with the direction of the prevailing wind towards the Southwest according to the station of the Meteorological Institute National park located above the Turrialba volcano.
