Source: M. Ritter

A vent is a conduit through which magma and gases travel to be extruded on to the surface as lava, volcanic gas, or pyroclastic material. The central vent is the main conduit through which magma rises to the surface. Lateral vents may form on the sides through which flank eruptions occur.
