The 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 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 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.

The Pacific Ring of Fire

About 90%?of the world’s earthquakes and 81%?of the world’s largest earthquakes occur along the Ring of Fire. All but three of the world’s 25 largest volcanic eruptions of the last 11,700 years occurred at volcanoes in the Ring of Fire.?The Ring of Fire is a direct result of?plate tectonics: the movement and collisions of?lithospheric?plates,?especially?subduction?in the northern portion. The southern portion is more complex, with a number of smaller tectonic plates in collision with the Pacific plate from the?Mariana Islands, the?Philippines,?Bougainville,?Tonga, and?New Zealand.
