- n. A large crater formed by volcanic explosion or by collapse of a volcanic cone.
Century Dictionary and Cyclopedia
- n. A large kettle or caldron; hence, in geology, an amphitheatrical depression in a volcanic formation. The term was originally used in describing volcanic regions occurring where Spanish is the current language, and was introduced by Von Buch in his classic description of the Canaries. Its use has been extended thence to other countries, and by it is understood a large amphitheatrical or kettle-like depression occurring in volcanic rocks, surrounded by high and steep walls, which are usually more or less broken away on one side or cut through by deep ravines (barrancas). Calderas are generally admitted to be volcanic craters enlarged by the action of the sea after submergence of the mass, or by the action of subterranean disruptive forces.
