ALASKA VOLCANO OBSERVATORY
Friday, September 12, 2003 10:00 AM ADT (18:00 UTC)
Seismic activity is monitored in real time at 24 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.
Wrangell, Spurr, Redoubt, Iliamna, Augustine, Snowy, Griggs, Katmai,
Novarupta, Trident, Mageik, Martin, Aniakchak, Veniaminof, Pavlof, Dutton,
Isanotski, Shishaldin, Fisher, Westdahl, Akutan, Makushin, Great Sitkin,
and Kanaga volcanoes are in color code GREEN. All are at or near normal
levels of background seismicity. AVO did not detect ash plumes or
significant elevated surface temperatures in the vicinity of any volcano.
ABBREVIATED COLOR CODE KEY (contact AVO for complete description):
GREEN volcano is dormant; normal seismicity and fumarolic activity
YELLOW volcano is restless; eruption may occur
ORANGE volcano is in eruption or eruption may occur at any time
RED significant eruption is occurring or explosive eruption
expected at any time
