Ukinrek Maars (Alaska, USA)

Aerial view, looking north, over the Ukinrek Maars on the south shore of Becharof Lake on the Alaska Peninsula. The maar craters formed during a 10-day eruption in March and April of 1977.

Volcano: Ukinrek Maars (see Ukinrek Maars at the Smithsonian Institution website in a new tab)
Type: Soil Diffuse Emission
Description: The Ukinrek Maars are two phreatomagmatic vents that formed on the north side of the Aleutian Range on a low area bordering the Bering Sea.Water began pooling in the craters soon after the eruption. CO2- rich gas bubbled up through hot (81 °C) saline water at the bottom of the western maar in late-August 1977, and in July 1979 both craters contained lakes with trains of gas bubbles visible from shore.
