Caldera

Caldera

Large, generally circular, fault-bounded depression caused by the withdrawal of magma from below a volcano or volcanoes. Commonly, the magma erupts explosively as from a giant volcano and, falling back to Earth as volcanic ash, fills the caldera so formed. Calderas are different from craters, which are smaller, circular depressions created primarily by explosive excavation of rock during eruptions.
