The Ring of Fire describes the margins of the Pacific Plate, which is ringed by volcanoes and experiences frequent catastrophic earthquakes, from New Zealand to Indonesia to Japan and Russia's Kamchatka, through Alaska's southern fringe along the entire western coast of the Americas.
Ring of Fire. The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. It has 452 volcanoes (more than 75% of the world's active and dormant volcanoes).[1] The Ring of Fire is sometimes called the circum-Pacific belt. About 90% of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire. The next most seismically active region (5â6% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt, which extends from Java to the northern Atlantic Ocean via the Himalayas and southern Europe.
