A major tsunami is caused by an earthquake, which occurs along or near a coast or in ocean area. Thus, a new approach for detecting a Tsunami and issuing the Warning System (TWS) is proposed as under:

1. Establishing an Earthquake Detecting and Tsunami Warning (ED&TW) Center.

2. Detection of exact location of the epicenter and magnitude of the earthquake.

3. Automatic computation using a hydro dynamical algorithm of the amplitude and velocity of the tsunami originating thereof.

This warning from the ED&TW Center would be the quickest possible for coordinated preparedness and management of response from tsunami disaster.
