The impacts of Iran’s recent and destructive earthquake of Mw 7.3 November 12 2017, and its important subsequent events are investigated at Sarpol-e-zahab by means of 1D-equivalent linear site response analyses. Local damages at Sarpol-e-zahab highlighted the role of seismic microzonation in seismic risk reduction and damage prevention plans for future events. Hence, the main goals of this study are set to provide maps for amplification factors and shaking levels of the city as well as validating design-basis earthquake loads for buildings and structures of the national code of IRSt2800. This is achieved by deconvolution of the strong motions recorded by ISMN-SPZ as the closest station to the epicenter of Mw 7.3 earthquake and finding the two horizontal bedrock motions and subsequently, convolution of the horizontal bedrock motions to find the ground motions at 38 points across the city. The results of seismic site response analyses have provided very instructive information for rehabilitation of the existing buildings and future constructions as well as seismic vulnerability assessment of buildings during earthquakes. Furthermore, it provides an unprecedented research in Iran of a complete seismic microzonation at urban scale after an earthquake and a successful application of seismic microzonation at urban area with inadequate number of strong motion recording stations.

2017年11月12日发生的伊朗7.3级地震和破坏性地震的影响及其后续重要事件，通过一维等效线性场地响应分析在Sarpol-e-zahab进行了研究。Sarpol-e-zahab的局部破坏凸显了地震微带在减少地震风险和预防未来事件的计划中的作用。因此，本研究的主要目标是为城市的放大系数和振动水平提供地图，并验证IRSt2800国家法规中建筑物和结构的设计基准地震荷载。这是通过将ISMN-SPZ记录为最接近7.3级地震震中的站点的强运动解卷积并找到两个水平基岩运动来实现的，然后，将水平基岩运动进行卷积以找到整个城市38个点的地面运动。地震现场响应分析的结果为现有建筑物和未来建筑的修复以及地震期间建筑物的地震易损性评估提供了非常有益的信息。此外，它为伊朗地震后城市规模的完整地震微区划和地震微区划在市区的成功应用提供了前所未有的研究，而该地区的强震动记录台数量不足。地震现场响应分析的结果为现有建筑物和未来建筑的修复以及地震期间建筑物的地震易损性评估提供了非常有益的信息。此外，它为伊朗地震后城市规模的完整地震微区划和地震微区划在市区的成功应用提供了前所未有的研究，而该地区的强震动记录台数量不足。地震现场响应分析的结果为现有建筑物和未来建筑的修复以及地震期间建筑物的地震易损性评估提供了非常有益的信息。此外，它为伊朗地震后城市规模的完整地震微区划和地震微区划在市区的成功应用提供了前所未有的研究，而该地区的强震动记录台数量不足。
