World Distribution of earth quake. The Pacific Ring of Fire accounts for about 65 per cent of all earthquakes and these are closely linked with the phenomenon of plate tectonics. Chile, California, Alaska, Japan, Philippines, New Zealand and the mid-ocean areas have had many minor and major earthquakes in this belt. Mountains here run along the border of continents and nearly parallel to the depressions in oceans. The sharpest break in relief in this belt is the cause of earthquake. The mid-world mountain belt extends parallel to the equator from Mexico across the Atlantic Ocean, the Mediterranean Sea from Alpine- Caucasus ranges’ to the Caspian, Himalayan mountains and the adjoining lands. This zone has folded mountains, large depressions and active volcanoes. The remaining 11 per cent of the shocks are recorded outside these two belts. Only a few occur along the fracture in African lakes, Red Sea and the Dead Sea zone.
