KVERT WEEKLY INFORMATION RELEASE 22-2023 Kamchatkan and Kuriles Volcanic Activity May 25, 2023, 22:33 UTC (May 26, 2023, 10:33 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. SUMMARY OF AVIATION COLOUR CODES: KAMCHATKA SHEVELUCH: ORANGE BEZYMIANNY: YELLOW AVACHINSKY, DIKY GREBEN, GAMCHEN, GORELY, ICHINSKY, ILIINSKY, KAMBALNY, KARYMSKY, KHANGAR, KHODUTKA, KIKHPINYCH, KIZIMEN, KLYUCHEVSKOY, KOMAROV, KORYAKSKY, KOSHELEV, KRASHENINNIKOV, KRONOTSKY, KSUDACH, MALY SEMYACHIK, MUTNOVSKY, OPALA, PLOSKY TOLBACHIK, TAUNSHITS, USHKOVSKY, VYSOKY, ZHELTOVSKY, ZHUPANOVSKY: GREEN NORTHERN KURILES EBEKO: ORANGE ALAID, ANTSIFEROV, CHIKURACHKI, CHIRINKOTAN, EKARMA, FUSS PEAK, KARPINSKY, KRENITSIN PEAK, KUNTOMINTAR, NEMO PEAK, SEVERGIN, SINARKA, TATARINOV: GREEN CENTRAL KURILES GORYASHCHY, PALLAS PEAK, PREVO PEAK, RAIKOKE, RASSHUA, SARYCHEV PEAK, USHISHIR, ZAVARITSKY CALDERA: GREEN SOUTHERN KURILES ATSONUPURI, BARANSKY, BERG, BERUTARUBE, BOGDAN KHMELNITSKY, BRAT CHIRPOEV, CHYORNOGO, GOLOVNIN, IVAN GROZNY, KOLOKOL, KUDRYAVY, MENDELEEV, SNOW, STOKAP, TREZUBETS, TYATYA: GREEN 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 eruption of the volcano continues. A danger of ash explosions up to 10 km (32,800 ft) a.s.l. is remains. Ongoing activity could affect international and low-flying aircraft. The extrusive volcanic eruption continues: lava blocks are squeezed out in the explosive crater of the Young Sheveluch, it is accompanied by powerful gas-steam activity, an incandescence of the lava dome, and sometimes hot avalanches. In the area of the Karan dome, powerful gas-steam activity is also observed, probably associated with the growth of a new lava dome. According to KVERT satellite data, thermal anomalies were observed in the area of the active volcano crater and Karan dome all week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Sheveluch EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 1156 m (3792 ft) Aviation Colour Code is ORANGE The moderate explosive eruption of the volcano continues. Ash explosions up to 6 km (19,700 ft) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk. The moderate explosive eruption of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 3.5 km a.s.l. on 23-25 May; ash clouds moved to the south, southeast, and east of the volcano. Satellite data by KVERT showed a thermal anomaly over the volcano on 24 May; an ash cloud drifted for 75 km to the southeast of the volcano on 25 May. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Ebeko BEZYMIANNY VOLCANO (CAVW #300250) 55.97 N, 160.6 E; Elevation 2882 m (9453 ft) Aviation Colour Code is YELLOW An extrusive-effusive eruption of the volcano continues. Ongoing activity could affect low-flying aircraft. An extrusive-effusive eruption of the volcano continues. The eruption is accompanied by gas-steam activity of the volcano and sometimes by the collapses of hot avalanches along the lava dome slopes.
