KVERT DAILY REPORT
Kamchatkan and Kuriles Volcanic Activity
October 03, 2025, 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 explosive-extrusive eruption of the Young Sheveluch volcano continues. According to video and satellite data by KVERT, explosions sent ash up to 3 km a.s.l., and ash plume extended for about 60 km to the southeast of the volcano; a thermal anomaly over the volcano was observed.

KRONOTSKY VOLCANO (CAVW #300200)
54.75 N, 160.53 E; Elevation 3528 m (11572 ft)
Aviation Colour Code is ORANGE

Probably an phreatic explosive eruption occured at the southern flank of Kronotsky volcano at 22:30 UTC on 03 October, 2025. An ash cloud rose up to 9 km a.s.l., and a large ash cloud moved for 360 km to the southeast of the volcano. Probably, the eruption of the volcano ended.

KRASHENINNIKOV VOLCANO (CAVW #300190)
54.6 N, 160.27 E; Elevation 1856 m (6088 ft)
Aviation Colour Code is ORANGE

An effusive eruption of the volcano continues: lava flows are effusing to the eastern slopes of the Northern Cone of the volcano, and a gas-steam emission from this Cone is observing. Satellite data by KVERT showed a plume of resuspended ash extended for 250 km to the southeast of the volcano; and a big thermal anomaly over the volcano.

BEZYMIANNY VOLCANO (CAVW #300250)
55.97 N, 160.6 E; Elevation 2882 m (9453 ft)
Aviation Colour Code is YELLOW

A gas-steam activity of the volcano continues. Satellite data by KVERT showed a thermal anomaly over the volcano.

Aviation Colour Codes

GREEN

Volcano is in normal, non-eruptive state

   or, after a change from a higher level:

Volcanic activity considered to have ceased, and volcano reverted to its normal, non-eruptive state.

YELLOW

Volcano is experiencing signs of elevated unrest above known background levels.    

 or, after a change from higher level:

Volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.

ORANGE

Volcano is exhibiting heightened unrest with increased likelihood of eruption.

   or,

Volcanic eruption is underway with no or minor ash emission.
[specify ash-plume height if possible]

RED

Eruption is forecast to be imminent with significant emission of ash into the atmosphere likely.

  or,

Eruption is underway with significant emission of ash into the atmosphere.
[specify ash-plume height if possible]
