Many earthquakes and volcanoes occur in an area that borders the Pacific Ocean. For that reason, this area has been known as the Ring of Fire. The Ring of Fire runs down the Earth's subduction zones. The Pacific Plate converges with many other plates to form the Ring of Fire.
Faulting during subduction causes earthquakes & volcanic mountain ranges. On the ocean floor, a deep narrow valley, called an ocean trench, may form along a subduction zone. Resulting volcanoes usually form along the trench, often along a curved line.
