AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, October 16, 2008, 2:04 PM AKDT (Thursday, October 16, 2008, 22:04 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 recorded on the Great Sitkin network remains low. The volcano was obscured by clouds in satellite images.

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

Low-level seismicity at Okmok Volcano continues. A weak thermal anomaly was observed in satellite images and is likely due to small lakes that have formed in the summit crater.



Although the level of seismicity is relatively low, it is possible for vigorous ash emissions to resume at any time.
