Regions of Earthquake Occurence
Circum-Pacific Ring of Fire
This is an area where a large number of earthquakes and volcanic eruptions occurs in the basin of the Pacific Ocean. The ring of fire is not quite a circular ring. It’s shaped more like 40,000km (25,000 miles) horseshoe. A string of 452 volcanoes stretches from the Southern tip of South America up to the coast of North America; across the Bering straits, down through Japan and into New Zealand.
