 (1) VOLCANO OBSERVATORY NOTICE FOR AVIATION (VONA)
 (2) Issued:20140724/0814Z
 (3) Volcano:Karymsky (CAVW #1000-13-)
 (4) Current Aviation Color Code:YELLOW
 (5) Previous Aviation Color Code:orange
 (6) Source:KVERT
 (7) Notice Number:2014-11
 (8) Volcano Location:N 54 deg 2 min E 159 deg 26 min
 (9) Area:Kamchatka, Russia
(10) Summit Elevation:4874.08 ft (1486 m)
(11) Volcanic Activity Summary:Weak seismic activity of the volcano continues but after July 04, seismic events were noting seldom. According to data by volcanologists, the volcano was quiet on July 17-23. Satellite data showed the volcano was quiet: ash plumes from the volcano were noted on April 04 last time; a thermal anomaly - on July 13 last time. However Karymsky is the very active volcano and its eruptive events could occur at any time. KVERT continues to monitor this volcano.

Activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft.
(12) Volcanic cloud height:NO ASH CLOUD PRODUCED
(13) Other volcanic cloud information:NO ASH CLOUD PRODUCED
(14) Remarks:Karymsky is one of the most active volcanoes of the Eastern zone. The eruptive style is represented with explosive and explosive-effusive eruptions. The major type of eruptions is Vulcanian, at some periods – Vulcanian-Strombolian.

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]
