The Ring of Fire is a horseshoe-shaped area surrounding much of the Pacific Ocean basin that experiences high levels of seismic and volcanic activity. It contains over 75% of the world's active and dormant volcanoes and is home to approximately 90% of the world's earthquakes, including 81% of the largest earthquakes. The Ring of Fire is associated with tectonic plate boundaries and movements and results in a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts around the Pacific Ocean.

Introduction Ring of fire Statistics
Disasters can happen anywhere and at any time. But some places experience more than their fair share of floods, tornadoes, hurricanes, winter storms and severe weather
The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. 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 and is home to over 75% of the world's active and dormant volcanoes.It is sometimes called the circum- Pacific belt or the circum-Pacific seismic belt.
The Ring of Fire is a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean. The Ring of Fire is not quite a circular ring. Its shaped more like a 40,000-kilometer (25,000- mile) horseshoe. A string of 452 volcanoes stretches from the southern tip of South America, up along the coast of North America, across the Bering Strait, down through Japan, and into New Zealand.

About 90%[2] of the world's earthquakes and 81%[3] of the world's largest earthquakes occur along the Ring of Fire. The next most seismically active region (56% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt, which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic Ridge is the third most prominent earthquake belt
