TSUNAMI EARLY WARNING SYSTEM ALONG THE GUJARAT COAST, INDIA

The great Sumatra earthquake (Mw 9.3) of 26th December, 2004, was rated as the world’s second largest recorded earthquake. The tsunami was considered as one of the deadliest natural hazards in the history, killing over 225,000 people in fourteen countries. In response to this disaster, the government of India took up the task of establishing an Early Warning System for Tsunamis. The Makran coast is extremely vulnerable to tsunamis and earthquakes due to the presence of three very active tectonic plates namely, the Arabian, Eurasian and Indian plates. On 28 November 1945 at 21:56 UTC, a massive Makran earthquake generated a destructive tsunami in the Northern Arabian Sea and the Indian Ocean. The tsunami was responsible for loss of life and great destruction along the coasts of Pakistan, Iran, India and Oman. In this paper NAMI-DANCE numerical model has been used to simulate 1945 Makran tsunamigenic source. In this study tsunami early warning system is try to develop by modeling of various tsunami scenarios and the worst case detect for location along coastal area of Gujarat, India. At the time of event, the closest scenario is picked from the database for emergency management of disaster and early warns to coastal community.
