Latest nearby earthquakes
The shield volcano was constructed during 2 north-migrating periods of activity that began with submarine eruptions and included formation of a circular tuff-ring complex enclosing the caldera.
The sides of a small volcanic horst in the center of the caldera display lava flows overlying a 2-m-thick halite bed, formed when sea water filled the caldera, creating an evaporite basin.
