  Abstract Natural disasters annually cause an average More than a thousand billion damages to the country. According to experts, Iran is one of the most prone areas of the earthquake and according to official statistics in the last 15 years, 6% of the earthquake casualties were earthquake. In this regard, assessing the seismic vulnerability of different regions of the country in order to reduce the vulnerability of urban communities should be a priority in planning. The purpose of this study was to investigate the role of topography in magnifying seismic effects in the Kalat-Naderi area of Khorasan Razavi province using Pessina et al. In this regard, first, the digital elevation model of sites prone to magnification of geomorphological effects was investigated. These effects included: ridge, peaks, hills, valleys with features such as slope shape, as well as slope and elevation difference. GIS functions were also used to classify critical areas. The resulting maps can be used to assess large-scale topographic areas of risk and earthquake risk. According to the results of the study, out of the total study area, 74.71% were in the range of low magnification, 21.12% in high class and 4.15% in high class. Manuscript profile
