Reliable damage and loss estimation models are essential for hazard analysis and emergency response planning. Geographic information systems (GIS) seem to provide an adequate framework for a computer based tool, which can be used for the implementation of a damage estimation methodology as well as for the visualisation of the results. In this thesis a client side implementation of Earthquake Simulation Software (EQSIM), a java based GIS analysis tool, which can be used for the calculation of damage scenarios, has been made. A detailed building database of an area is required to get the damage map. Because seismic response spectra are essential for the damage estimation, EQSIM provides two possibilities:  calculation of response spectra using attenuation relations and use of response spectra from recorded time histories. Capacity and fragility curves are used to describe the behaviour of the different building types for the specified response spectra. Use of open source projects was made to implement the analysis tool which has resulted in it being a cost effective tool. The client-server architecture for this tool has resulted in increased speed of calculations as compared to its older version. A damage scenario map based on the available data has been carried out for the IIT Kanpur and its adjoining region.
