Explosive-effusive 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.
Explosive-effusive eruption of the volcano continues: there are bursts of volcanic bombs to 200-300 m above the summit crater and up to 50 m above the cinder cone into Apakhonchich chute, and strong gas-steam activity of two volcanic centers with emission of different amounts of ash, the effusing of lava flows along Apakhonchich chute at the south-eastern flank of the volcano.
According to the video data, an intensification of the eruption was noted on 06 July: strong explosions sent ash up to 7.5 km a.s.l. According to satellite data by KVERT, a large bright thermal anomaly in the area of the volcano was observed all week, ash plumes drifted for about 350 km to the southwest, south and southeast from the volcano on 02-05 July; and dense ash plumes drifted for about 400 km to the southeast and east from the volcano on 06-07 July.
