GEOLOGY

Detailed explanation-1: -Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

Detailed explanation-2: -While most earthquakes are caused by the slipping of tectonic plates, minor earthquakes can also be caused by volcanic eruptions, collapse of rock formations on Earth’s surface, or underground explosions.

Detailed explanation-3: -An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction.

Detailed explanation-4: -Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the ‘Ring of Fire’; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
