What are volcanic steam vents?
The vents billow when ground water seeps down to the hot volcanic rocks and generates continuous plumes of steam. Just a few feet below the surface, the ground is so hot that tree roots can’t survive; exercise caution and remain behind the railings and barriers at the park.
What is unique about the Kilauea volcano?
Kilauea is an active volcano, and the most active of the five volcanoes. It has been erupting continuously since 1983. Kilauea is estimated to be between 300,000 and 600,000 years old. It is located along Hawaii’s south shore, and is believed to have reached sea level approximately 100,000 years ago.

- Noticeable steaming or fumarolic activity and new or enlarged areas of hot ground.
- Subtle swelling of the ground surface.
- Small changes in heat flow.
- Changes in the composition or relative abundances of fumarolic gases.
What is the smoke that comes out of a volcano called?
