Observers in Perryville, 20 miles south of Veniaminof, report seeing a small steam plume over the volcano yesterday. Ash deposits from last week's activity darkened snow along the caldera rim, but no ash fell in Perryville. Pollen was mistaken for fresh tephra at Chignik Lake, 25 miles east of the volcano.
COOK INLET VOLCANOES
The large avalanche detected on Iliamna last week was entirely of snow and ice, indicating that this event was not related to volcanin processes. Seismic activity at Spurr, Augustine, Redoubt and Iliamna volcanoes remains at normal levels.
The Alaska Volcano Observatory continues to seismically
monitor Spurr, Augustine, Redoubt and Iliamna volcanoes.
We maintain a computerized alarm system that is capable of
notifying AVO seismologists during non business hours
should unusual seismic activity occur.
