where does most seismic activity occur on earth
Earthquake Most of the world's earthquakes (90%, and 81% of the largest) take place in the 40,000Â 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.[39][40] Massive earthquakes tend to occur along other plate boundaries, too, such as along the Himalayan Mountains.[41]
