VONA/KVERT DAILY REPORT
Kamchatkan and Northern Kuriles Volcanic Activity
May 25, 2016, 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 showed a thermal anomaly over the lava dome.

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

Explosive-effusive eruption of the volcano continues. According to video and satellite data, the lava flow continues to effusing on the south-eastern flank of the volcano (along Apakhonchich chute). Satellite data showed a thermal anomaly over the volcano.

ALAID VOLCANO (CAVW #290390)
50.86 N, 155.56 E; Elevation 7672 ft (2339 m)
Aviation Color Code is ORANGE

A weak activity of the volcano continues. Satellite data showed the volcano was quiet.

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

A weak gas-steam activity of the volcano continues. Satellite data showed the volcano was quiet.

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

A weak activity of the volcano continues. Satellite data showed the volcano was quiet.

ZHUPANOVSKY VOLCANO (CAVW #300120)
53.59 N, 159.15 E; Elevation 9702 ft (2958 m)
Aviation Color Code is YELLOW

A weak activity of the volcano continues. Satellite data 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]
