Geographical Information Systems (GIS) primarily based modeling and Remote Sensing (RS) methods can help by supplying roadmaps and methods as assist with make early on warning intended for risk areas. In this case study, different criteria have been assessed that have potential impact on how much devastation, like the elevation of the areas, water damage depth, building density, landscape slope, garden soil type, area use types etc .

According to the results of the Earthquake Disaster Risk Index (EDRI) project, main earthquake risk is associated with the high vulnerability of the building stock due to both poor materials and poor building processes.
