Pacific Ring of Fire
Pacific Ring of Fire is the area in the basin of Pacific Ocean, where a large number of volcanic eruptions and earthquakes occur. This ring is the house of 75 percent of world's active and dormant volcanoes. The Ring of Fire has been created as a result of plate tectonics and the movement and collisions of lithospheric plates.
