IEDA / DECADE Detail

Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Katmai

Katmai caldera, a collapse feature formed during the catastrophic eruption of the nearby Novarupta vent in June 1912 is seen here in an aerial view from the NE. The steep-walled, 1.5-km-wide Katmai caldera truncates a formerly 2290-m-high cluster of overlapping stratovolcanoes. The caldera is partially filled by a blue-green lake that is about 250 m deep and rising. Beyond the caldera are the multiple peaks of Trident volcano; Mageik volcano is the snow-and-ice-covered cone on the skyline.
