ALASKA VOLCANO OBSERVATORY STATUS REPORT U.S. Geological Survey Saturday, October 25, 2008, 2:05 PM AKDT (Saturday, October 25, 2008, 22:05 UTC)
KASATOCHI VOLCANO
(VNUM #311130)
52°10'9" N 175°30'41" W,
Summit Elevation 1030 ft (314 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Seismicity at Kasatochi as determined from the network on Great Sitkin Island remains at low. A weak thermal anomaly, likely associated with the crater lake, was noted in satellite data. AVO has received no additional observations about activity at Kasatochi volcano.
Kasatochi Volcano does not have a seismic network, thus AVO depends on networks on neighboring islands to monitor earthquake activity there. For this reason, low-level seismicity may not be detected and renewed volcanic activity is possible at any time with little or no warning.
OKMOK VOLCANO
(VNUM #311290)
53°23'49" N 168°9'58" W,
Summit Elevation 3520 ft (1073 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Seismic activity at Okmok Volcano remains at low to near-background levels. A weak thermal anomaly, likely associated with a lake in the caldera, was noted in satellite data.
Although the level of seismicity is relatively low, it is possible that vigorous ash emissions will resume.
