KVERT DAILY REPORT
Kamchatkan and Kuriles Volcanic Activity

May 23, 2020, all time is UTC

SHEVELUCH VOLCANO (CAVW #300270)
56.64 N, 161.32 E; Elevation 10768 ft (3283 m), the dome elevation ~8200 ft (2500 m)
Aviation Colour Code is ORANGE


A growth of the lava dome continues, a strong fumarolic activity sometimes with some amount of ash and an incandescence of the dome blocks and hot avalanches accompanies this process. Satellite data by KVERT showed a thermal anomaly over the volcano.

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


A moderate explosive-effusive eruption of the volcano continues. The Strombolian and gas-steam with some amount of ash activity is observing. The lava flow continues to move on the southeastern flank of the volcano (the Apakhonchich chute), phreatic bursts and collapse of loose slag material accompany this process. Satellite data by KVERT showed a thermal anomaly over the volcano.

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


A moderate eruptive activity of the volcano continues. According to visual data by volcanologists from Severo-Kurilsk, explosions sent ash up to 2.5 km a.s.l., clouds drifted to the north-east of the volcano. Satellite data by KVERT showed the volcano was quiet.

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


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

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


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

Aviation Color 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]
