The steam vents are caused by underground heat sources, which boil ground water and return it to the surface as water vapor. This phenomenon is also visible just down the trail at Steaming Bluffs.

On the way to Kilauea you reach the point where it steams out of the holes. Here you can see the first signs that a volcano is working in the underground here.
