The circum-Pacific seismic belt, often referred to as the Ring of Fire, experiences more earthquakes than anywhere else on Earth. The belt stretches from the southern tip of the Americas north to Alaska, across the Bearing Strait, down through Japan and into New Zealand.
Over 80 percent of the world's earthquakes occur along the Ring of Fire. The seismic belt itself is a transform boundary formed by the motion of tectonic plates as they slide next to each other. The Ring of Fire is also home to most of the active volcanoes in the world, with eruptions occurring from New Zealand to the Pacific Northwest and South America.
