caldera

noun

[kal-ˈder-ə]

Definition of caldera

: a volcanic crater that has a diameter many times that of the vent and is formed by collapse of the central part of a volcano or by explosions of extraordinary violence

Did You Know

A large, bowl-shaped volcanic depression, a caldera forms when the top of a volcanic cone collapses into the space left after magma is ejected during a violent volcanic eruption. Its diameter is many times that of the original vent. The term is Spanish for "caldron." Subsequent minor eruptions may build small cones on the floor of the caldera, and the caldera may still later fill up with water; an example of this is Crater Lake in Oregon.
