KASATOCHI VOLCANO
(VNUM #311130)
52°10'9" N 175°30'41" W,
Summit Elevation 1030 ft (314 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code:
ORANGE
Seismic activity at Kasatochi continues to be detected by the AVO seismic network on Great Sitkin Island 25 miles to the west. Clouds have obscured the volcano in satellite views. No plumes have been reported.
The volcano remains in a restless condition and is still considered hazardous to approach.
CLEVELAND VOLCANO
(VNUM #311240)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code:
ORANGE
Clouds have obscured the volcano in satellite views. No plumes have been reported.
AVO monitors Cleveland volcano with satellite imagery as weather allows. The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions of ash that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery. Please see http://www.avo.alaska.edu/activity/Cleveland.php for more information.
OKMOK VOLCANO
(VNUM #311290)
53°23'49" N 168°9'58" W,
Summit Elevation 3520 ft (1073 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code:
ORANGE
Eruptive activity continues at Okmok Volcano. The seismic intensity and tremor duration are still above background levels suggesting that minor ash and steam emissions are still occurring.
