volcanic vent
Earth's pressure release
A volcanic vent is an opening in the Earth's surface through which magma, gases, and volcanic debris escape during eruptions.
Vents range from small fissures to the main crater of a volcano.
Secondary vents may form on a volcano's flanks: Lava flowed from a new vent on the mountain's eastern slope.
