A volcano's main vent is the point in the Earth's crust where hot magma has reached the surface. The cone-shape of a volcano builds up as ash, rock and lava ejected during eruptions fall back to Earth around the vent.

A volcano consists of a primary crater at the top. There can also be secondary craters near the top of the volcano. Vents are places along the sides of a volcano where lava can escape. The isn't usually a single primary vent within a volcano and a side-erruption can occur within any exting vent or indeed through the creation of a new vent.
Mt. Etna, as an example, has 4 craters at the top and around 300 side vents.
