VONA/KVERT DAILY REPORT
Kamchatkan and Northern Kuriles Volcanic Activity

August 23, 2017, 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 Color Code is ORANGE


A growth of the lava dome continues (a viscous lava flow reveal in the northern its part), strong fumarole activity, ash explosions, hot avalanches and an incandescence of the dome blocks and hot avalanches accompany 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 Color Code is ORANGE


A moderate eruptive activity of the volcano continues. Satellite data by KVERT showed an ash plume extended up to 220 km to the north-west from the volcano.

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


A moderate eruptive activity of the volcano continues: an incandescence of the lava dome is observing at night and a lava flow is squeezing at the north-western flank of the lava dome. 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 Color Code is ORANGE


A moderate eruptive activity of the volcano probably continues. Satellite data by KVERT showed the volcano was obscured by clouds.

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


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

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]
