Ring of Fire the bases of the volcanoes, which decreases the speed of erosion by an issue of perhaps a thousand relative to volcanoes in moist temperate or tropical climates. Ring of Fire The Ring of Fire is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur. In a large horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements. It has 452 volcanoes (more than 75% of the world's active and dormant volcanoes). The Ring of Fire is sometimes called the circum-Pacific belt.
Ring of Fire holding the record for the second-largest earthquake in the world, the Good Friday earthquake, and having more than 50 volcanoes which have erupted since about 1760. Volcanoes can be found not only in the mainland, but also in the Aleutian Islands. The most recent activity in the American portion of the Ring of Fire occurred in early 2009 when Mount Redoubt in Alaska became active and finally erupted late in the evening of March 22. The eruption ended in May 2009. The Public Safety Geo-science Program at the Natural Resources Canada undertakes research to support risk reduction from the effects
