CURRENT STATUS REPORT
Saturday, August 27, 2005 3:00 PM AKDT (23:00 UTC)
ALASKA VOLCANOES WITH ELEVATED COLOR CODES:
MOUNT SPURR VOLCANO
61°18'N 152°15'W, Summit Elevation 11,070 ft. (3,374 m)
Current Level of Concern Color Code: YELLOW
The level of seismic activity at Mt. Spurr volcano remains above background. Satellite and webcam views were obscured by clouds today. There are no indications that conditions at the volcano are changing or that an eruption is imminent.
52°49'N 169°57W, Summit Elevation 5,674 ft. (1,730 m)
Current Level of Concern Color Code: Not assigned
(Note: Cleveland volcano does not have a real-time seismic network; volcanoes without seismic networks are not assigned a color code of Green because without the seismic data, AVO has no definitive information that the level of activity of the volcano is at background)
AVO lowered the color code for Cleveland volcano from Yellow to "Not Assigned" today. The last evidence of activity at Cleveland was a thermal feature seen in a satellite image August 11. Since then AVO has had several good satellite views of the volcano, but no evidence of further activity has been seen. Also, we have not received any pilot reports of activity. AVO moved Cleveland to color code Yellow on July 7 when satellite images showed increased heat flow, thin ash deposits, and possible debris flows extending down the volcano’s flanks.
