Alaska Volcanoes Update
Friday, January 31, 1997, 10:00 AM AST (1900 UTC)
Pavlof Volcano: 55.42°N, 161.9°W; 8,262 ft
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW
The eruptive pause at Pavlof Volcano is now beginning its fifth week.
AVO seismometers continue to record very low levels of seismicity
at the volcano. AVO received no pilot reports of activity this
week. Ground observations from Cold Bay and Nelson Lagoon
today and earlier in the week during a break in the weather
confirm that there is no eruptive activity at the volcano.
Based on comparisons to other historical eruptions at Pavlof, it is
possible that this pause will persist for weeks or months,
followed by resumption of ash and lava emission with little or no
warning. Accordingly, AVO continues to monitor the volcano
closely and will issue further updates as the situation changes.
Iliamna Volcano: 60.04°N, 153.17°W; 10,196 ft elevation
The seismic swarm that began on 1 August 1996 beneath Iliamna
Volcano continued during the past week at an average rate of about
3 earthquake per day.
