A large crater formed by a volcanic explosion or by collapse of the cone of a volcano
An enlarged volcanic crater formed by explosion or collapse of the original crater
a large, roughly circular depression usually caused by volcanic collapse or explosion
A large, usually circular depression at the summit of a volcano formed when magma is withdrawn or erupted from a shallow underground magma reservoir The removal of large volumes of magma may result in loss of structural support for the overlying rock, thereby leading to collapse of the ground and formation of a large depression
A large, basin-shaped depression formed by the inward collapse of a volcano after or during an eruption (movie)
Large, bowl-shaped volcanic depression that forms when the top of a volcanic cone collapses into the space left after magma is ejected during a violent volcanic eruption. The term is Spanish for "caldron." Subsequent minor eruptions may build small cones on the floor of the caldera which may still later fill up with water; an example is Crater Lake in Oregon
a very large basin-shaped crater Calderas are found at the tops of volcanoes, where the original peak has collapsed into an empty chamber beneath
An elliptic or circular depression bordered by a cliff, topping a volcano and resulting from the collapse of the roof of a magma chamber caused by a very powerful eruption
(a) A volcanic crater created by collapse or explosive eruption, usually having a diameter of greater than 2 km (b) A large depression in the ground due to the goblins not needing it any more Some go quietly (collapse) but some fail to come to terms with this redundancy (explosive eruption)
A large, basin-shaped volcanic depression that is more or less circular in form Most volcanic calderas are produced by collapse of the roof of a magma chamber due to removal of magma by voluminous eruptions or subterranean withdrawal of the magma, although some calderas may be formed by explosive removal of the upper part of a volcano
a large, more or less circular, more-than-a-mile-in-diameter depression formed either by collapse or by explosion, usually at the summit of a volcano
A large crater formed by volcanic explosion or by collapse of the cone of a volcano
The crater or bowl-shaped depression formed at the summit of a volcano or by the collapse of a magma chamber
A type of volcanic crater that is extremely large, usually formed by the collapse of a volcanic cone or by a violent volcanic explosion Crater Lake is one example of a caldera on Earth
The Spanish word for cauldron, a basin-shaped volcanic depression; by definition, at least a mile in diameter Such large depressions are typically formed by the subsidence of volcanoes Crater Lake occupies the best-known caldera in the Cascades
A large volcanic depression at the summit of a volcano, caused by collapse or explosion
On some volcanoes, the magma chamber collapses after a violent eruption and a caldera forms, which is just a large, bowl-shaped crater
