Kilauea: Mountain of Fire
Kilauea: Mountain of Fire
Kilauea, on Hawaii's Big Island, is the world's most active volcano. Its latest eruption began in 1983 and it hasn't stopped since. Since that time it has created 544 acres of new land and has consumed 200 homes. But Kilauea is also the driving force in a spectacular process of creation -- the cataclysmic meeting of 2,000-degree lava and 75-degree ocean water.
