An observer from Port Heiden (40 km west of the volcano) reported sighting small, dark plumes from Veniaminof on the 17 of April, 1995. Observers from Perryville, Alaska (20 km south of the volcano) report that Veniaminof volcano has been producing a small steam plume over the past several days. This information coincides with reported warm spots seen on satellite images taken on April 14 and 21, 1995. Veniaminof volcano has been experiencing low levels of eruptive activity for more than a year and a half. Steam clouds from melting ice and snow caused by contact with warm lava and occasional low-energy, ash bursts from the intercaldera cone have been common.
COOK INLET VOLCANOES
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 nonbusiness hours,
should unusual seismic activity occur.
