At night, through clouds in the crater there is a constant glow and emissions of small bombs at a height of 100 m above the crater rim. Lava flows on the volcano slopes were observed.
April 23 began on Klyuchevskoy an increase in activity of the volcano. There were several strong earthquakes and volcanic ash plumes (determined by satellite images).
The night of April 25, there was a small lava flow 500 m long on the southeast slope of Klyuchevskoy (There is a video camera KB GS RAS). Emissions seemed to contain ashes.
Explosive volcanic eruption of Strombolian type continues. Satellite data by KVERT showed an intensive thermal anomaly over the volcano all week. Strong explosions sent ash up to 8-9 km a.s.l. near 13:40 UTC on 23 April, and ash cloud continues to drift to the south-west of the volcano. At 02:28 UTC on April 24, the leading edge of the ash cloud is an estimated 453 km south-west of the volcano.
Explosive eruption of the volcano continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.
