ALASKA VOLCANO OBSERVATORY WEEKLY UPDATEFriday, March 12, 2010 09:45 AM (Friday, March 12, 2010 18:45 UTC)

No eruptive activity or unrest has been detected at volcanoes in Alaska this week. Daily status reports remain suspended as long as there are no volcanoes at elevated color codes or alert levels.

MONITORED ALASKAN VOLCANOES

Seismic activity is monitored in real time at 27 volcanoes in Alaska. Satellite images of all Alaskan volcanoes are analyzed daily for evidence of ash plumes and elevated surface temperatures. Some volcanoes may currently display anomalous behavior but are not considered to be at a dangerous level of unrest. Akutan, Augustine, Dutton, Fisher, Gareloi, Great Sitkin, Griggs, Iliamna, Isanotski, Kanaga, Katmai, Mageik, Makushin, Martin, Novarupta, Okmok, Pavlof, Redoubt, Shishaldin, Snowy, Spurr, Tanaga, Trident, Ugashik-Peulik, Ukinrek Maars, Westdahl, and Wrangell volcanoes are in color code GREEN and volcano alert level Normal. All are at or near normal levels of background seismicity.
