Tsunami hazard and alert system for Western Coast of Gujarat

In Western Coast of Gujarat destructive tsunamis have been generated from large earthquakes along the Makran Coast, Chagos Ridge and Kutch Region in the past. Although the historical record is incomplete, it is believed that such Tsunamis were destructive on the coasts of India, Pakistan, Iran, Oman and Sri Lanka and possibly had significant effects on Islands. The most significant tsunami genic earthquake in recent times was that of 28 November 1945 21:56 UTC with a magnitude of 8. In this paper an attempt is made for an alert system for tsunami warning system for the possible tsunami risk from Makran Subduction Zone (MSZ). It is observed from the results that the simulated arrival time of tsunami waves at the Western Coast of Gujarat is in good agreement with the available data sources. In this study more importance has been given to the run up height of tsunami waves, arrival time and inundation map. Also in this paper an attempt has been made to develop efficient user friendly tsunami warning system along with study of evacuation options for the western coast of Gujarat.
