What was the reason for the disappearing of the Indira point?
Sea waves which can go very high are called tsunamis. Tsunami is a Japanese word meaning harbour waves. Tremors produced by intense earthquakes that occur in the sea create gigantic waves. Till it reaches the shore these waves are not noticed because they are only about a metre high. But when they reach the shore, they become very gigantic and powerful. They travel at about 800 km per hour and rise up to 30 metres high. These tsunami waves that travel thousands of kilometres in the sea without causing any harm, cause widespread devastation when they reach and hit the shore. Some islands may totally disappear due to this. The disappearance of the Indira Point on the Andaman & Nicobar Islands is an example for this.
