tsunami propagation in arabian sea and its effect on dwarka city of gujarat, india

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 tsunamigenic earthquake in recent times was that of 28 november 194521:56 utc (03:26 ist) with a magnitude of 8.1 (mw). in this paper an attempt is made for a numerical simulation of the tsunami generation from the makran subduction zone, and its propagation into the arabian sea and its effect on the dwarka city of gujarat, india, through the use of a numerical model. it is observed from the results that the simulated arrival time of tsunami waves at the dwarka 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 effect of different fault parameters on basic data is also studied.
