Ring of Fire explanation 1:33
The large series of volcanoes (some active) encircling the Pacific Ocean are referred to as being part of the Ring of Fire, and notorious for frequent earthquakes and volcanic eruptions. The Ring of Fire, coinciding with the edges of one of the world's main tectonic plates, (the Pacific Plate) contains over 450 volcanoes and is home to approximately 75% of the world's active volcanoes. Nearly 90% of the world's earthquakes occur along the Ring of Fire; most recently, the devastating quakes in Chile, Japan and New Zealand.
