KVERT DAILY REPORT Kamchatkan and Kuriles Volcanic Activity October 18, 2023, all time is UTC SHEVELUCH VOLCANO (CAVW #300270) 56.64 N, 161.32 E; Elevation 3283 m (10768 ft), the dome elevation ~2500 m (8200 ft) Aviation Colour Code is ORANGE An extrusive-effusive eruption of the volcano continues: a lava is extruding into the explosive crater of the Young Sheveluch, it is accompanied by powerful gas-steam activity, and sometimes an incandescence of the lava dome. In the area of the Karan dome, powerful gas-steam activity is also observed. Satellite data by KVERT showed a thermal anomaly over the volcano. KLYUCHEVSKOY VOLCANO (CAVW #300260) 56.06 N, 160.64 E; Elevation 4750 m (15580 ft) Aviation Colour Code is ORANGE An explosive-effusive eruption of the volcano continues. Against the background of explosive activity of the Strombolian type (lava fountaining in the volcanic crater), the lava flows continue to effuse along the Kozyrevsky and Apakhonchichsky chute on the southern slopes of the volcano. Satellite data by KVERT showed a large thermal anomaly over the volcano. BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 2882 m (9453 ft) Aviation Colour Code is ORANGE The paroxysmal explosive eruption of the volcano occurred at 04:30 UTC on 18 October. Satellite data by KVERT showed: large explosions send ash up to 11 km a.s.l., and ash cloud moved to the north-northeast, and then northwest of the volcano. A large thermal anomaly was observing over the volcano. EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 1156 m (3792 ft) Aviation Colour Code is ORANGE A moderate activity of the volcano continues. Satellite data by KVERT showed the volcano was obscured by clouds. CONTACT INFORMATION: Duty scientist: Olga A. Girina, E-mail: girina(a)kscnet.ru Tel.

Against the background of explosive activity of the Strombolian type (lava fountaining in the volcanic crater), the lava flows continue to effuse along the Apakhonchichsky chute on the southeastern slope of the volcano. Lava flows in the Apakhonchichsky chute melt buried snowfields and glaciers. Powerful phreatic explosions are observed in the Apakhonchichsky chute, and large collapses of pyroclastic material from its sides. A gray-red ashfall began to be observed in Klyuchi from 19:00 UTC on 16 October. This confirms that this is old ash from the Klyuchevskoy volcano from the sides of the Apakhonchichsky chute. An ash cloud gradually moves to the northeast of the volcano. There are currently no large pyroclastic collapses observed in the Apakhonchichsky chute. KVERT continues to monitor Klyuchevskoy volcano.\n\nThe summit explosive-effusive ! eruption of the volcano continues. Ash explosions up to 7-8 km (23,000-26,240 ft) a.s.l. could occur at any time.
