Assessment of landslide hazard across mountains is imperative for public safety. Pre- and post-earthquake landslide mapping envisage that landslides show significant size changes during earthquake activity. One of the purposes of earthquake-induced landslide investigation is to determine the landslide state and geometry and draw conclusions on their mobility. This study was based on remote sensing data that covered 72 years, and focused on the west slopes of the Skolis Mountains, in the northwest Peloponnese. On 8 June 2008, during the strong Movri Mountain earthquake (Mw = 6.4), we mapped the extremely abundant landslide occurrence. Historical seismicity and remote sensing data indicate that the Skolis Mountain west slope is repeatedly affected by landslides. The impact of the earthquakes was based on the estimation of Arias intensity in the study area. We recognized that 89 landslides developed over the last 72 years. These landslides increased their width (W), called herein as inflation or their length (L), termed as enlargement. Length and width changes were used to describe their aspect ratio (L/W). Based on the aspect ratio, the 89 landslides were classified into three types: I, J, and Δ. Taluses, developed at the base of the slope and belonging to the J- and Δ-landslide types, are supplied by narrow or irregular channels. During the earthquakes, the landslide channels migrated upward and downward, outlining the mobility of the earthquake-induced landslides. Landslide mobility was defined by the reach angle. The reach angle is the arctangent of the landslide’s height to length ratio. Furthermore, we analyzed the present slope stability across the Skolis Mountain by using the landslide density (LD), landslide area percentage (LAP), and landslide frequency (LF). All these parameters were used to evaluate the spatial and temporal landslide distribution and evolution with the earthquake activity. These results can be considered as a powerful tool for earthquake-induced landslide disaster mitigation

基于事件的清单方法在滑坡灾害评估中的应用：以希腊伯罗奔尼撒西北部斯科利斯山脉为例

评估山区滑坡灾害对公共安全至关重要。地震前和地震后的滑坡图设想，在地震活动期间，滑坡会显示出明显的大小变化。地震诱发滑坡研究的目的之一是确定滑坡的状态和几何形状，并就其流动性得出结论。这项研究基于长达72年的遥感数据，重点是伯罗奔尼撒西北部的斯科利斯山脉的西坡。2008年6月8日，在Movri山强烈地震（Mw = 6.4）期间，我们绘制了极为丰富的滑坡发生图。历史地震和遥感数据表明，斯科里斯山西坡多次受到滑坡的影响。地震的影响是基于对研究区域的咏叹调强度的估计。我们认识到在过去72年中发生了89次滑坡。这些滑坡增加了其宽度（W），在本文中称为膨胀或其长度（L）（称为扩大）。长度和宽度的变化用于描述其纵横比（L / W）。根据长宽比，将89个滑坡分为三种类型：I，J和Δ。在斜坡底部形成的Taluse由狭窄或不规则的通道提供，属于J型和Δ型滑坡。在地震期间，滑坡通道向上和向下迁移，概述了地震诱发的滑坡的流动性。滑坡的活动性由到达角定义。到达角是滑坡高度与长度之比的反正切值。此外，我们使用滑坡密度（LD），滑坡面积百分比（LAP）和滑坡频率（LF）分析了Skolis山目前的边坡稳定性。所有这些参数都用于评估地震活动的时空滑坡分布和演化。这些结果可以被认为是减轻地震诱发的滑坡灾害的有力工具。
