ALASKA VOLCANO OBSERVATORY STATUS REPORT

U.S. Geological Survey

Tuesday, October 28, 2008, 12:33 PM AKDT (Tuesday, October 28, 2008, 20:33 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 low. A satellite image today shows a thermal anomaly in the crater likely associated with the warm crater lake.




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. Clouds obscured satellite views of the volcano today.




Although the level of seismicity is relatively low, it is possible, but growing increasingly unlikely, that vigorous ash emissions will resume.
