Kilauea is a Hawaiian word that means spewing. The Puu Oo cone has been spewing ash and lava since 1983. Kilauea has erupted 36 times since 1952. Ninety percent of Kilauea is covered in lava. This volcano is about the most active volcano in the world, making it the most visited volcano in Hawaii.
Kilauea is the youngest volcano on Hawaii, estimated at 600,000-years-old. This mountain, appearing more as a bulge, started its life as a submarine volcano and worked its way to the surface about 100,000 years ago. About 90 percent of Kilauea is under the sea.
