Earthquake associated risk poses obstacle to developmental process as well as threat to the livelihood of the resident population, especially in metropolitan cities in developing countries. In order to mitigate and manage the natural disasters, there is an urgent need to adopt various techniques and tools like GIS to design and develop a procedure that will enable the city administrators and responsible disaster management personnel to evaluate earthquake severity and potential impact on the facilities, and suggested associated levels of post-earthquake monitoring response for different magnitude earthquakes occurring within certain distances from the urban amenities and facilities. Hence this proto-type using ArcGIS have been focused on three major components, i.e., Hazard Mapping, Risk Analysis and Post –quake relief planning. Vulnerability analysis was derived from population and estimated building property while Post-quake relief planning focus on quake-hit areas and compared with available general amenities and services such as hospitals, police stations, fire stations etc. Macro level analyses are being attempted with sample Gujarat Data sets and micro level with Ahmedabad data sets to demonstrate the potential.
