उत्तर
Earthquakes primarily occur along two major belts: the Circum-Pacific Belt (Ring of Fire) and the Mid-World Mountain Belt. The Circum-Pacific Belt surrounds the Pacific Ocean and includes Japan, Indonesia, and the American West Coast. The Mid-World Mountain Belt runs from the Mediterranean to the Himalayas to Southeast Asia. Most earthquakes occur in these areas when tectonic plates meet and move.
