KVERT WEEKLY INFORMATION RELEASE 17-2025
Kamchatkan and Kuriles Volcanic Activity
April 24, 2025, 07:48 UTC (April 24, 2025, 19:48 KST)
KVERT monitor active volcanoes of Kamchatka and the Kurile Islands. Not all of these volcanoes had eruptions in historical time, however they are potentially active and therefore are of concern to aviation.

CENTRAL KURILES
GORYASHCHY, PALLAS PEAK, PREVO PEAK, RAIKOKE, RASSHUA, SARYCHEV PEAK, USHISHIR, ZAVARITSKY CALDERA: GREEN
SOUTHERN KURILES

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. The danger of ash explosions up to 10 km (32,800 ft) a.s.l. remains. Ongoing activity could affect international and low-flying aircraft.
The extrusive-effusive eruption of the Young Sheveluch volcano and the activity of the 300 years RAS lava dome continue. The growth of the lava domes is accompanied by powerful gas-steam emissions. Satellite data by KVERT showed thermal anomalies over the both domes on 20-21 April, the volcano was obscured by clouds in the other days of the week.

BEZYMIANNY VOLCANO (CAVW #300250)
55.97 N, 160.6 E; Elevation 2882 m (9453 ft)
Aviation Colour Code is ORANGE
The activity of the volcano continues. Ongoing activity could affect low-flying air craft.
The effusive eruption of the volcano continued throughout the week, accompanied by the collapse of hot avalanches and increased gas-steam activity. According to KVERT satellite data, a large thermal anomaly was observed in the area of the volcano all week. At approximately 01:45 UTC on 23 April, ash was transported up to 9 km a.s.l., an ash cloud 10 × 10 km in size was moving north-northwest from the volcano. A strong explosive eruption of the volcano began at 23:10 UTC on 23 April - explosions send ash up to 11 km a.s.l., the ash cloud moved for 390 km to the southwest of the volcano. Ash falls occurred in the villages of Atlasovo, Lazo, Milkovo. An ash cloud 100 × 120 km continues to move southwest of the volcano.

KLYUCHEVSKOY VOLCANO (CAVW #300260)
56.06 N, 160.64 E; Elevation 4750 m (15580 ft)
Aviation Colour Code is YELLOW
The activity of the volcano continues. Ongoing activity could affect low-flying aircraft.
The explosive eruption of Strombolian type of the volcano began on 20 April, 2025. An incandescence over the volcano crater was noted first time at 10:04 UTC on 20 April, 2025. Satellite data by KVERT showed a thermal anomaly over the volcano on 18-22 April; the volcano was obscured by clouds in the other days of the week.

KARYMSKY VOLCANO (CAVW #300130)
54.05 N, 159.44 E; Elevation 1486 m (4874 ft)
Aviation Colour Code is YELLOW
A moderate activity of the volcano continues. The danger of ash explosions up to 10 km (32,800 ft) a.s.l. remains. Ongoing activity could affect international and low-flying aircraft.
A moderate activity of the volcano continues. Satellite data by KVERT showed a weak thermal anomaly over the volcano on 18-20 April; the volcano was obscured by clouds in the other days of the week.

In Russia, KVERT, on behalf of the Institute of Volcanology and Seismology (IVS) FEB RAS, is responsible for providing information on volcanic activity to international air navigation services for the airspace users.
KVERT scientists are available in the office from 8:30 AM till 6:00 PM (KST) 7 days in week and by phone during the evenings since 2005. KVERT produces daily satellite monitoring (since 2002 till now) of Kamchatkan and Kuriles Volcanoes to using the information system (IS) “Remote monitoring of the activity of Kamchatka and Kuriles volcanoes (VolSatView)”, which was created in 2011-2014 the joint efforts of the scientists of KVERT IVS FEB RAS, the Space Research Institute RAS, the Computing Center FEB RAS and the Far Eastern Scientific Center Planet. IS continues to evolve. KVERT analyses information from remote scientific observation stations and seismic data for volcanoes: Alaid, Avachinsky, Bezymianny, Gorely, Karymsky, Kizimen, Klyuchevskoy, Koryaksky, Mutnovsky, Plosky Tolbachik, Sheveluch, Ushkovsky, Zhupanovsky (from the Kamchatkan Branch of Geophysical Survey RAS); and other information to monitor activity at Kamchatkan and Kuriles Volcanoes.
