Earthquake

The shaking and vibrating of the earth's surface is called an earthquake. The shaking may vary between very small tremors to a violent vibration.

Types of earthquake

On the basis of the nature of shaking, earthquakes are classified as vertical and horizontal. In the vertical earthquake, the vibration is up and down and in the horizontal earthquake, the vibration is lateral. Horizontal earthquake is more devastating because collapsing of buildings occur more in it.
