You might know it best as the title of a song, but the Ring of Fire is actually a massive belt of volcanoes and seismic activity around the Pacific Ocean.
The Ring of Fire is a horseshoe-shaped string of volcanoes and seismic sites that nearly encircles the Pacific Ocean. Stretching from South America up to Alaska and down to New Zealand, it contains more than 450 volcanoes. Because of the constant movement of tectonic plates in the region, 90 percent of the world's earthquakes occur in the Ring of Fire. This intense geological activity makes it one of the most volatile and fascinating areas on Earth.
