摘要
西孟加拉邦主要位于喜马拉雅山山麓的苏尔玛山谷,靠近阿萨姆-阿拉干造山带的西部前陆。该地区经常能感觉到几次低到中等震级的地震。在这项研究中,我们使用综合多准则决策(MCDM)模型来评估西孟加拉邦的地震易损性。24个易受该地区地震活动影响的参数被用于评估岩土、结构、社会和物理脆弱性。采用层次分析法(AHP)对各参数的优先级进行估计,然后采用VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR)和加权和法(WSM)对地震易损性进行估计。结果表明,约17.81%的总面积和65.36%的人口可能处于高至非常高易损区,引起规划和减灾的关注。通过估计的接收机工作特性曲线对结果进行验证,表明AHP-VIKOR方法对地震易损性的估计具有较好的效果。这项研究的结果可以帮助各种减灾和规划机构确定地震易损区,并为该地区可能发生的任何潜在的大地震提前做好准备。
Estimating seismic vulnerability in West Bengal by AHP-WSM and AHP-VIKOR
West Bengal is situated primarily in the Surma Valley at the foothills of the Himalayas and near the western foreland of the Assam-Arakan Orogenic Belt. Several low to moderate-magnitude earthquakes are felt in the region frequently. In this study, we use integrated multi-criteria decision-making (MCDM) models to assess the seismic vulnerability in West Bengal. Twenty-four parameters that were susceptible to seismicity in the region have been used to evaluate geotechnical, structural, social, and physical vulnerability. The analytical hierarchy process (AHP) model was used to estimate the priorities of the parameters, which was then used to estimate seismic vulnerability using the VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) and the weighted sum method (WSM). The results reveal that approximately ∼17.81% of the total area and ∼65.36% population may fall under a high to very high-vulnerable zone, causing concerns for planning and disaster mitigation. The receiver operating characteristic curve estimated to validate the results, indicate that the AHP-VIKOR performs better for seismic vulnerability estimation. The results of this study may help various mitigation and planning agencies in identifying earthquake-vulnerable zones and preparing in advance for any potential large magnitude earthquakes that may occur in the region.
