Paper Title
Tsunami Evacuation System for Western Coast of Gujarat in Mandvi City

This paper presents the mapping of some cities of western coast of Gujarat for Tsunami evacuation. The various coastal cities of Gujarat have been studied Mandvi cities are taken as case study. The need for the study is to aware people for the hazard of tsunami and saving maximum lives when tsunami occurs there.In this paper the past historical earthquakes of Tsunami-genic source of Makaran Subduction zone which is responsible for causing tsunami on western coast of Gujarat are studied. The time of arrival of tsunami on the cities of interest is known and the area according topography developed by DEM (Digital Elevation Model) is shown. The elevation of coastal region of 1 to 6 m heights is indicated by different colours in the map and according to distance from shoreline and topography of the ground evacuation maps are prepared.For some cases it is not feasible to use the evacuation route as the large distance is to be determined so at some places vertical evacuation structures (VES) are required to be provided. According to FEMA P646, the suggestions of VES are considered and according to that VES are proposed to some places.
