What Pacific belt contains about 75 percent of Earth’s volcanoes? The Ring of Fire does.

The Ring of Fire, also called the Circum-Pacific belt, forms a broad arc around much of the Pacific Ocean. It is not a single continuous geological structure. Instead, it is a chain of volcanic arcs, ocean trenches, and earthquake zones created mainly where tectonic plates converge and one plate sinks beneath another in a process called subduction.

The belt stretches for roughly 25,000 miles and includes major volcanic regions in the Andes, Central America, the Cascades, Alaska, Kamchatka, Japan, the Philippines, and parts of Oceania. It contains hundreds of active or dormant volcanoes, although the exact percentage depends on how volcanoes and the belt’s boundaries are counted; modern estimates often describe roughly two-thirds of the world total.

A common mix-up is treating the Ring of Fire as a ring of volcanoes caused by one giant crack. It is actually a collection of interacting plate boundaries. The same tectonic activity also produces about 90 percent of the world’s earthquakes.
