Ring of Fire

Ring of Fire

A belt of seismic and volcanic activity roughly surrounding the Pacific Ocean. It includes the Andes Mountains of South America, the coastal regions of western Central America and North America, the Aleutian and Kuril islands, the Kamchatka Peninsula, Japan, the island of Taiwan, eastern Indonesia, the Philippines, New Zealand, and the island arcs of the western Pacific. About three-fourths of all historically recorded active volcanoes have occurred in this belt. See also plate tectonics.
