KVERT DAILY REPORT
Kamchatkan and Kuriles Volcanic Activity

April 26, 2024, 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 extrusive-effusive eruption of the volcano continues: a lava is extruding into the explosive crater of the Young Sheveluch, it is accompanied by powerful gas-steam activity, and sometimes an incandescence of the lava dome. In the area of the Karan dome, powerful gas-steam activity is also observed. Satellite data by KVERT showed a thermal anomaly over the volcano.

Based on continuous satellite observations by KVERT, we believe that a new extrusive dome appeared in the Karan Dome area on the Sheveluch Volcano around 15:00 UTC on April 26, 2024. The Value of Temperature Difference between the thermal Anomaly and the Background (the VTDAB) increased sharply from 8 to 59.7 °C around 15:00 UTC on April 26, 2024 and reached 95 °C by 16:23 UTC. KVERT continues to monitor the Sheveluch volcano.

EBEKO VOLCANO (CAVW #290380)
50.69 N, 156.01 E; Elevation 1156 m (3792 ft)
Aviation Colour Code is ORANGE


A moderate activity of the volcano continues. According to visual data from Severo-Kurilsk, and satellite data by KVERT the volcano was obscured by clouds.

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


An effusive eruption of the volcano continues; a strong fumarolic activity and sometimes an incandescence of the lava dome is accompanied this process. 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]
