GIS is effective in carrying out geological, civil engineering analysis as automated processes within the GIS, and different outcomes resulting form changed input parameters, assumptions and scenarios can be easily compared with due consideration given to uncertainties in methodology and the input data. The modern space-based remote sensing, spatial science and geo information technologies have opened up efficient means for tectonic studies and evaluation of earthquake risk and mitigation strategy. Fault rupture and associated surface deformation, can be observed using Aster satellite data. The measurement of fault displacements using satellite image in Esfahan has brought more care for rehabilitation and vulnerability. The field checks and lab analysis beside remote sensing techniques show that Esfahan may be affected by 5-6 Richter earthquakes. In this research, the earthquake hazard analysis of Emam Square (Naghsh-e-Jahan) is being evaluated as a case study.
