The Pacific Ring of Fire is home to earthquakes and volcanoes of the Earth. The "Ring of Fire" is an arc stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. The Ring of Fire is composed over 75% of the world's active and dormant volcanoes.
Discovery and Location of the Pacific Ring of Fire

This huge ring of volcanic and seismic activity was noticed and described before the invention of the theory of plate tectonics theory. We now know that the Ring of Fire is located at the borders of the Pacific Plate and other major tectonic plates.
Shifting Plates in the Pacific Ring of Fire

Plates are like giant rafts of the earth's surface which often slide next to, collide with, and are forced underneath other plates. Around the Ring of Fire, the Pacific Plate is colliding with and sliding underneath other plates. This process is known as subduction and the volcanically and seismically active area nearby is known as a subduction zone.

There is a tremendous amount of energy created by these plates and they easily melt rock into magma, which rises to the surface as lava and forms volcanoes. Volcanoes are temporary features on the earth's surface and there are currently about 1500 active volcanoes in the world.
