Veniaminof Volcano - John Seach
Alaska
56.17 N, 159.38 W
summit elevation 2507 m
stratovolcano
Veniaminof volcano is one of the highest in Alaska.
The volcano contains an 8 x 11 km wide glacier-filled caldera. The caldera is filled by an ice field that ranges in elevation from approximately 1750 to 2000 m. A line of vents extends 55 km from Bering Sea coast, across the caldera, and down the Pacific flank.
The westernmost of two caldera cones has been the source of historical eruptions. A large magnitude (VEI 6) eruption occurred at the volcano about 1750 BC. The eruption was from a central vent and caused caldera collapse and pyroclastic flows.
2008 Activity
Small ash eruptions occurred at the volcano in February 2008. Emissions rose a few hundred feet above the active intracaldera cinder cone.
