KVERT DAILY REPORT
Kamchatkan and Kuriles Volcanic Activity
August 21, 2026, 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

A growth of the lava dome of the volcano continues, this process is accompanied by powerful gas-steam emissions; a new block of lava continues to grow in the northern part of the lava dome. Satellite data by KVERT showed the volcano was obscured by clouds.

KLYUCHEVSKOY VOLCANO (CAVW #300260)
56.06 N, 160.64 E; Elevation 4750 m (15580 ft)
Aviation Colour Code is ORANGE

The summit explosive eruption of the volcano continues. According to satellite data by KVERT, a gas-steam plumes with some amount of ash rose up to 5.5 km a.s.l. (05:00Z; 17:20Z). An ash plumes extended for 300 km to the northeast of the volcano.

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

An effusive activity of the volcano continues, this is accompanied by powerful gas-steam emissions.Satellite data by KVERT showed the volcano was obscured by clouds.

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

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 sometimes with some amount of ash from this Cone is observing. Satellite data by KVERT showed a bright thermal anomaly on 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]

UNASSIGNED

There is insufficient information available to assess the current status of the volcano or volcanic activity.
