The Ring Of Fire

Figure by USGS

Volcanoes usually form at the boundaries of tectonic plates (where the Earth’s crust moves apart or collides). The Ring of Fire is a 25,000-mile long horseshoe-shaped “ring” that circles the Pacific Ocean. It is called the Ring of Fire because that is where most of Earth’s volcanoes are found.

The Ring of Fire is also a Johnny Cash song, to which geologists love to make their own silly volcano parodies.

There are 452 volcanoes in the Ring of Fire, and it is home to 75% of the world’s volcanoes and about 90% of the world’s earthquakes.
