Tsunami Emergency Response System Using Geo-information Technology along the Western Coast of India

The Makran coast is extremely vulnerable to tsunamis and earthquakes due to the presence of three very active tectonic plates namely, the Arabian, Eurasian and Indian plates. On 28 November 1945 at 21:56 UTC, a massive Makran earthquake generated a destructive tsunami in the Northern Arabian Sea and the Indian Ocean. The tsunami was responsible for loss of life and great destruction along the coasts of Pakistan, Iran, India and Oman. In this paper tsunami early response system created using classification of tsunami susceptibility along the western coast of India. Based on the coastal topographical features of selected part of the western India, we have prepared regions susceptible to flooding in case of a mega-tsunami. Geo-information techniques have proven their usefulness for the purposes of early warning and emergency response. These techniques enable us to generate extensive geoinformation to make informed decisions in response to natural disasters that lead to better protection of citizens, reduce damage to property, improve the monitoring of these disasters, and facilitate estimates of the damages and losses resulting from them. The classification of tsunami risk zone (susceptible zone) is based on elevation vulnerability by Sinaga et al. (2011). We overlaid satellite image on the tsunami risk map, and identified the region to be particularly at risk in study area. In our study satellite images integrated with GIS/CAD, can give information for assessment, analysis and monitoring of Tsunami Emergency Response System Using Geo-Information Technology along the Western Coast of India http://www.iaeme.com/IJCIET/index.asp 81 [email protected] natural disaster. We expect that the tsunami risk map presented here will supportive to tsunami early response system along the western coast of India.
