The volcano has a circular summit caldera, about 100 m deep, containing a frozen lava and several cinder cones from probably relatively recent eruptions. Young lava flows cover most of the volcano's flanks. At present, there is fumarolic activity.
Introduction:
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.
