| Abstract: |
| An earthquake is one of the natural hazards that is not possible to predict the exact time of occurrence.. Interpolation is the one of the ways which can identify and determine the dangerous zone in the earthquake region. Interpolation method helps to identify the unknown points in the earthquake regions. Which are including the IDW, Spline, and Kriging methods, were evaluated based on their prediction error (RMSE). The result showed the Kriging method with the lowest of RMSE was selected as the best method for spatial analysis of seismic risk in the earthquake region with the impact magnitude (7.3) earthquake on November 2017. RMSE of interpolation method shows IDW= 0/665, Spline =0/649 and Kriging =0/647. The density layer of population map obtained from the spline method showed, about 20.5% of the residential population are located in the fault areas. By kriging method of an interpolation a map with assessing indicators based on GIS principles was obtained. Therefore this map as a low risk of earthquake for hesitance was proposed. In order to increase the accuracy of the interpolation, the comparison was made with the ground data. The result of the interpolation methods with the earthquake report of the region was similarity. The focal points of the earthquakes occurred to the faults in the area and close to faults, and this result showed the recent earthquakes have a significant relationship with the faults. The main reason that seismic calendar, of Sarpol-e-Zahab has been changed, the aftershocks with the >6 richer magnitudes… |
