. Because of its remote and inaccessible location, most information about the volcano comes from aerial surveys. The volcano was discovered during an aerial survey in 1946. The Prizrak caldera has a diameter of about . It is located on top of the site of an ancient stratovolcano whose base has a diameter of about . The slopes of the caldera feature a network of erosional valleys. Within the Prizrak caldera complex are at least three partially nested calderas, each about in diameter. Kell is the largest of several small stratovolcanoes, composed mainly of lava, in the innermost portion of the caldera. The caldera also contains

lava dome In volcanology, a lava dome is a circular, mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. Around 6% of eruptions ...
