KVERT DAILY REPORT
Kamchatkan and Kuriles Volcanic Activity
February 28, 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

A growth of the lava dome of the Young Sheveluch volcano, and the 300 years of RAS (the Russian Academy of Sciences) lava dome on the southwestern slope of the Old Sheveluch volcano continues. A growth of the domes is accompanied by powerful gas-steam activity. Satellite data by KVERT showed thermal anomalies over the both lava domes.

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

An effusive eruption of the volcano continues, this is accompanied by powerful gas-steam emissions and hot avalanches. Satellite data by KVERT showed a bright thermal anomaly over the volcano.

KARYMSKY VOLCANO (CAVW #300130)
54.05 N, 159.44 E; Elevation 1486 m (4874 ft)
Aviation Colour Code is ORANGE

A moderate activity of the volcano continues. Satellite data by KVERT showed the volcano was quiet.

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]
