A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Volcano is a 1997 disaster film directed by Mick Jackson and produced by Andrew Z. Davis, Neal H. Moritz and Lauren Shuler Donner. The storyline was conceived from a screenplay written by Jerome Armstrong and Billy Ray. The film features Tommy Lee Jones, Anne Heche, and Don Cheadle. Jones is cast as the head of the Los Angeles County Office of Emergency Management (LAC OEM) which has complete authority in the event of an emergency or natural disaster. His character attempts to divert the path of a dangerous lava flow through the streets of Los Angeles following the formation of a volcano at the La Brea Tar Pits.
