Need for World Tsunami Awareness Day

It is estimated that around 50% of the world population will live in coastal areas by 2030. This population will be exposed to all natural disasters such as flooding, tsunamis and storms. Therefore, it is important to scale up the international cooperation and stay prepared and resilient to tsunamis.

Tsunamis

The word Tsunami means “Harbour waves”. It is a Japanese word. It is a series of giant waves created by earthquakes, under water landslides and undersea volcanic eruptions. The tsunami waves travel at a speed of 800 kilometre per hour. They can reach to a height of 300 feet. Around 80% of the tsunamis occur in Pacific Ocean. The speed of the tsunami is fast in deep waters and slow in shallow waters. The deadliest Tsunami occurred in December 2004 and killed more than 2.27 lakh people.
