The Cinque Terre National Park (38 km2) has recently recorded a remarkable increase in tourists involved in outdoor activities such as hiking. However, due to the actual slope degradation issues that affect this outstanding terraced landscape, hiking trails are increasingly threatened by the impact of landslides. This produces severe landslide-related risk scenarios for hikers. In this study, a landslide inventory map (at 1:45000 scale) has been prepared through the revision/update of previous database and the analysis of air-photos and satellite images coupled with field surveys. Furthermore, a quantitative evaluation of the interaction between landslides and hiking trails has been performed by the definition of a Footpath Landslide Index. More than 400 landslides were identified highlighting that these phenomena represent the main source of hazard. The findings of this study reveal that side-hill trails are the most hazardous since hikers can be potentially affected by flow-like or fast-moving landslides.

五渔村国家公园(意大利)的滑坡清单和与足迹网络的定量相互作用

五渔村国家公园(38 km 2)最近记录到,参加远足等户外活动的游客人数显着增加。然而,由于实际的坡度退化问题影响了这一杰出的梯田景观,因此,远足径越来越受到滑坡的威胁。这给徒步旅行者带来了与滑坡有关的严重风险。在这项研究中,通过修订/更新以前的数据库,并通过空中照片和卫星图像分析以及现场调查,准备了滑坡清单图(比例为1:45000)。此外,通过定义人行道滑坡指数,对滑坡与远足径之间的相互作用进行了定量评估。识别出400多个滑坡,突出表明这些现象是造成灾害的主要根源。
