In the last 10 years, also due to climate change, extreme rain events have affected the Basilicata region (southern Italy) causing landslides and floods that have damaged urban fabric, commercial activities and transport infrastructures. In many of these cases, the civil protection system, involving national (DPC) and regional (DRPC) Civil Protection Departments, was activated to manage the emergency phase in cooperation with local administrations and scientific institutions, which in this context are referred to as competence centres (CdCs). Among the latter, the Institute of Methodologies for Environmental Analysis (IMAA) of the Italian National Research Council (CNR) has been frequently involved in carrying out geophysical investigations in landslide areas, especially during the post-event phase. This paper reports the main results of the in-field geophysical surveys carried out in two areas of the Basilicata region affected by significant landslides in the last 10 years. The aim of the surveys was to provide the DRPC technicians with a useful subsoil geophysical model to improve the knowledge of the geological setting of the slope, to reconstruct the geometry of landslide body and to highlight high water content areas, in order to support the decision-making process. At the end of the paper, a discussion follows with the lessons learned from each case study along with recommendations on how to possibly improve the application of geophysical techniques in landslide investigations in order to further increase their impact.

巴西利卡塔（意大利）滑坡区民防部门 10 年地球物理测量的经验教训

在过去 10 年中，同样由于气候变化，极端降雨事件影响了巴西利卡塔地区（意大利南部），引发了山体滑坡和洪水，破坏了城市结构、商业活动和交通基础设施。在其中许多情况下，涉及国家 (DPC) 和地区 (DRPC) 民防部门的民防系统被启动，以与地方行政部门和科学机构合作管理紧急阶段，在这种情况下，这被称为权限中心 (CdC)。在后者中，意大利国家研究委员会（CNR）的环境分析方法研究所（IMAA）经常参与滑坡地区的地球物理调查，尤其是在事后阶段。本文报告了过去 10 年在巴西利卡塔地区受重大滑坡影响的两个地区进行的实地地球物理调查的主要结果。调查的目的是为 DRPC 技术人员提供有用的地下地球物理模型，以提高对斜坡地质环境的了解，重建滑坡体的几何形状并突出高含水量区域，以支持决策——制作过程。在论文的最后，讨论了从每个案例研究中汲取的经验教训，以及关于如何可能改进地球物理技术在滑坡调查中的应用以进一步增加其影响的建议。
