预测地震诱发滑坡的敏感性分析最经常使用确定性方法，多元统计方法以前没有应用。然而，在这项研究中，我们引入了一种统计方法，使用地震震动的强度作为滑坡的触发因素。此方法应用于台湾中西部浅层地震诱发的山崩研究。结果表明，该方法可以准确地解释研究区滑坡的分布，并预测邻近地区滑坡的发生。该敏感性模型能够预测在地震情况下诱发的浅层滑坡，具有类似的地面震动范围，而不需要使用岩土工程，地下水或故障深度数据。(C)2008 Elsevier B.V.保留所有权利。
Susceptibility analysis for predicting earthquake-induced landslides has most frequently been done using deterministic methods; multivariate statistical methods have not previously been applied. In this study, however, we introduce a statistical methodology that uses the intensity of earthquake shaking as a landslide triggering factor. This methodology is applied in a study of shallow earthquake-induced landslides in central western Taiwan. The results show that we can accurately interpret landslide distribution in the study area and predict the occurrence of landslides in neighboring regions. This susceptibility model is capable of predicting shallow landslides induced during an earthquake scenario with similar range of ground shaking, without requiring the use of geotechnical, groundwater or failure depth data.
