Recent Eruptions from U.S. Volcanoes

Hawaiian volcanoes

 Few places on Earth allow closer or more dramatic views of volcanic activity than Mauna Loa and Kilauea volcanoes on the island of Hawaii. Their frequent but usually nonexplosive eruptions make them ideal for scientific study. Kilauea's eruptions are so intensely monitored that scientists have assembled a detailed picture of the volcano's magma reservoir "plumbing" system and how it behaves before and during eruptions. Studies of these volcanoes and the surrounding ocean floor continue to improve our understanding of the geologic history of the Hawaiian Island chain and the ability of scientists to determine volcanic hazards that threaten island residents.
