What 10 countries surround the ring of fire? Its length is approximately 40,000 kilometers (24,900 miles). The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The Pacific Plate, which drives much of the tectonic activity in the Ring of Fire, is cooling off. Geologic features along the Ring of Fire include not only volcanoes, but ocean trenches, mountain trenches, hydrothermal vents, and sites of earthquake activity. Volcanoes along the Ring of Fire are formed when one plate is shoved under another into the mantle – a solid body of rock between the Earth’s crust and the molten iron core – through a process called subduction. The Ring of Fire was formed as oceanic plates slid under continental plates.
