No. Volcano is a noun describing a mountain or hole in the ground through which lava, ash, and gas can erupt. Volcanic is an adjective that means "of, relating to, or produced by a volcano or volcanoes."
Such a hole is called a fumarole.
Do you mean the hole it comes out of the ground through? That is a volcano. More likely, you mean the hole made when the lava starts to cool and the liquid part inside can suddenly run out. That is a lava tube.
