<P> Most of the world 's earthquakes ( 90 % , and 81 % of the largest ) take place in the 40,000 km long , horseshoe - shaped zone called the circum - Pacific seismic belt , known as the Pacific Ring of Fire , which for the most part bounds the Pacific Plate . Massive earthquakes tend to occur along other plate boundaries , too , such as along the Himalayan Mountains . </P>
