An earthquake is a natural phenomenon which occur in our country and also in other parts of the world.
An earthquake in simple words is the shaking of the earth. It is a natural event. It is caused due to release of energy, which generates waves that travel in all directions.
The vibrations called seismic waves are generated from earthquakes that travel through the Earth and are recorded on instruments called seismographs.
The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
