Every year many earthquakes occurs around the world and some of them are highly destructive. Therefore, the study of the vulnerable areas to the earthquakes seems crucial. Current paper presents a novel method for the assessment of areas, which are prone to the earthquakes, using relative tectonic activity index (IAT). IAT is calculated via six morphometric indices, including Asymmetry factor, Mountain Front Sinuosity, Valley Floor width, Hypsometric Integral, Average of Channel Mean Slope and Drainage Basin Shape. Every index has some limits to show the magnitude of tectonic activity and sometimes they are not clear enough and need a reliable and accurate scoring method to reduce the uncertainty of the calculation results. Morphometric Indices, as the key factors in determining the tectonics situation of an area, were analyzed via fuzzy inference system to improve the accuracy of decision making in the IAT calculation, as the suggested method in present paper for the earthquake vulnerability assessment. Torbat-e-Jam basin was selected as a case of paper to operate the proposed method. Results showed that about 0.87 percent of paper area has the high IAT and is high risk of earthquake, consequently. About 82.47 and 16.66 percent of paper are determined as the moderate and low IAT, respectively. The map of the earthquake intensity of the paper area was plotted, afterwards, to check whether the results of presented method are reliable, and it approved that. The above method, thus, is applicable in those areas, which do not have enough seismologic data.

每年世界各地都会发生许多地震，其中一些地震具有很强的破坏性。因此，对地震脆弱地区的研究显得至关重要。目前的论文提出了一种使用相对构造活动指数（IAT）评估地震易发地区的新方法。IAT 通过六个形态测量指标计算，包括不对称因子、山前曲折度、谷底宽度、Hypsometric Integral、渠道平均坡度和排水盆地形状的平均值。每种指标在反映构造活动的大小方面都有一定的局限性，有时不够清晰，需要一种可靠、准确的评分方法，以减少计算结果的不确定性。形态指标作为决定区域构造形势的关键因素，通过模糊推理系统进行分析，以提高 IAT 计算中决策的准确性，作为本文建议的地震脆弱性评估方法。Torbat-e-Jam 盆地被选为纸箱来操作所提出的方法。结果表明，大约0.87%的纸张区域具有高IAT，因此具有高地震风险。大约 82.47% 和 16.66% 的论文分别被确定为中等和低 IAT。之后绘制了纸区地震烈度图，以检查所提出方法的结果是否可靠，并同意。因此，上述方法适用于地震资料不足的地区。作为本文建议的地震脆弱性评估方法。Torbat-e-Jam 盆地被选为纸箱来操作所提出的方法。结果表明，大约0.87%的纸张区域具有高IAT，因此具有高地震风险。大约 82.47% 和 16.66% 的论文分别被确定为中等和低 IAT。之后绘制了纸区地震烈度图，以检验所提出方法的结果是否可靠，并同意。因此，上述方法适用于地震资料不足的地区。作为本文建议的地震脆弱性评估方法。Torbat-e-Jam 盆地被选为纸箱来操作所提出的方法。结果表明，大约0.87%的纸张区域具有高IAT，因此具有高地震风险。大约 82.47% 和 16.66% 的论文分别被确定为中等和低 IAT。之后绘制了纸区地震烈度图，以检验所提出方法的结果是否可靠，并同意。因此，上述方法适用于地震资料不足的地区。87% 的纸张区域具有高 IAT，因此是高地震风险。大约 82.47% 和 16.66% 的论文分别被确定为中等和低 IAT。之后绘制了纸区地震烈度图，以检验所提出方法的结果是否可靠，并同意。因此，上述方法适用于地震资料不足的地区。87% 的纸张区域具有高 IAT，因此是高地震风险。大约 82.47% 和 16.66% 的论文分别被确定为中等和低 IAT。之后绘制了纸区地震烈度图，以检验所提出方法的结果是否可靠，并同意。因此，上述方法适用于地震资料不足的地区。
