KVERT reported that a thermal anomaly over Chikurachki was identified on 21 June and an explosive eruption occurred on 24 June.
Explosions recorded during 0730-2100 on 24 June (local time) produced ash plumes that rose to 4.5 km (14,800 ft) a.s.l.
A 14 x 30 km ash cloud was visible in satellite images at 0850 drifting 25 km SE, prompting KVERT to raise the Aviation Color Code to Orange (the second highest level on a four-color scale).
A VONA issued at 1445 on 25 June (local time) stated that only gas-and-steam emissions were rising from the volcano and that the Aviation Color Code was lowered to Yellow.
The ash cloud from the explosive phase had drifted about 790 km SE.
Satellite images on 26 June indicated no additional explosions; gas-and-steam emissions persisted.
At 1624 (local time) the Aviation Color Code was lowered to Green.
