Coastal areas of Andhra Pradesh in the north eastern part of India are mostly vulnerable for accelerated erosion haz-ards. Along the 200 km of coastline most of the coastal are-as, towns and industries are threatened by reoccurring of storms, flood events and sever coastal erosion. The east coast of India is mostly affected by tropical cyclones origi-nating from northern and southern Bay of Bengal, where 1-2 tropical cyclones form every year along the coast. Recently two tropical cyclones that formed in the Bay of Bengal are Hudhud (October 13, 2014) and Phylin (October 11, 2013) has caused devastating impact on the eastern coast. With this study, it is an attempt to develop to develop a coastal vulner-ability index (CVI) for the Andhra Pradesh using eight rela-tive risk variables. Most of these parameter are dy-namic in nature and requires different data from differ-ent sources. The base data is from remote sensing satellites, for others it is taken from long-term in situ measurements and from numerical models. Zones of vulnerability to coastal, natural hazards of different magnitude (high, medi-um and low) are identified and shown on map. In this study, tsunami run-up has been considered as an additional physi-cal process parameter to calculate the CVI. In earlier studies, tidal range are assumed to include both permanent and episodic inundation hazards....
