ALASKA VOLCANO OBSERVATORY

INFORMATION RELEASE

Wednesday, February 22, 2006 10:15 AM AKST (1915 UTC)




AUGUSTINE VOLCANO (CAVW#1103-01-)

59°21'48"N 153°26'W , Summit Elevation 4134 ft (1260 m)

Current Level of Concern Color Code: ORANGE



The purpose of this Information Release is to outline some changes in the way AVO reports information about Augustine Volcano. Since mid January, AVO has been posting hourly updates to the AVO website and sending daily Information Releases with details about volcanic unrest at Augustine. Because activity has been declining gradually over the past week, we will be changing the number and timing of web postings and Information Releases.



Beginning this afternoon, information about activity at Augustine will be posted to the AVO website every six hours unless a change in activity warrants more frequent postings. Daily status reports for volcanoes at elevated color codes (yellow, orange, or red) will continue; these reports will provide a brief summary of activity over the past 24 hours. A more thorough description of activity and a summary of the events of the week will be posted on Fridays, about noon, as an AVO weekly update.



AVO continues to monitor Augustine 24/7, and should activity increase again, we will begin reporting information on a more frequent basis.







ABBREVIATED COLOR CODE KEY (contact AVO for complete description):

GREEN volcano is dormant; normal seismicity and fumarolic activity occurring

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

ADVISORY
Volcano is exhibiting signs of elevated unrest above known background level or, after a change from a higher level, volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.
WATCH
Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway but poses limited hazards.
