What causes earthquakes according to science?

Question

Earthquakes are natural disasters that occur in many parts of the world. But what is the scientific reason behind the shaking of the ground? Understanding this concept is important in general science as well as geography.

Answer 1

Earthquakes occur mainly because of movements in the Earth’s tectonic plates. The Earth’s crust is not a single piece; it is made of several large and small plates that float on the semi-liquid mantle layer. When these plates collide, slide past each other, or move apart, stress builds up at the boundaries. When this stress is suddenly released, it causes the ground to shake. This release of energy is what we feel as an earthquake.

Most earthquakes occur along plate boundaries such as the Pacific Ring of Fire.

Answer 2

The point beneath the Earth’s surface where the energy is released is called the focus, and the point directly above it on the surface is called the epicenter. Earthquakes can also be caused by volcanic activity, mining, and large reservoirs, but tectonic movements are the most common cause. For competitive exams, remember: Plate movement = stress = sudden release = earthquake.
