WITHDRAWN Estimating Tsunami Vulnerability along Western Coast of India

Description: 

WITHDRAWN India has a long coastline of roughly 1500 km along its western margins. Tsunami hazards along western coast of India have been under-studied, comparative to the eastern coast. The major hazard of tsunami along western coast comes from Makran subduction zone. However, other features in Arabian sea and Western and Northern Indian ocean may pose also pose a threat, in terms of tsunami. Seafloor topography reveals various tectonic features that can possibly trigger tsunamis. These comprise of Indian ocean mid-oceanic ridge including carlsberg ridge, owen fracture zone, among others. These features primarily have earthquakes of strike-slip in origin. It has been shown that stirke-slip earthquakes have potential of generating tsunamis, contrary to popular belief. Slope failure, favourable bathymetry, large dip angle, are some of the feature which faciliates tsunamigenic nature of strike-slip earthquakes. Another common reason of tsunami is underwater landlslides. One such region is Indus canyon, in the north western indian ocean. In this study, possible tsunami harzard estimation for the western coast of India have been done, by taking hypothethical earthquake scenarios along several features in Arabian sea and North and North west Indian ocean. Inundation and Run-Up for each case has been discussed, higlighting vulnerability of the region.
