Recent Eruptions from U.S. Volcanoes
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.
