Volcano: Ukinrek Maars (see Ukinrek Maars at the Smithsonian Institution website in a new tab)
Type: Volcanic Plume
Description: The Ukinrek Maars are two phreatomagmatic vents that were created in an area without previous volcanic activity during a 10-day-long phreatomagmatic eruption March-April 1977. The basaltic maars were erupted through glacial deposits in the Bering Sea lowlands 1.5 km south of Becharof Lake and 12 km west of Peulik volcano; their location is related to the regional Bruin Bay fault.
