The Integrated Landslides Monitoring System of Gimigliano Municipality, Southern Italy

Abstract

Monitoring the stability of a slope is one of the non-structural measures aimed at reducing the risk of landslides. Displacement detection is now possible through numerous monitoring techniques, including remote sensing and ground-based solutions. In particular, in-situ monitoring allows some advantages related to using low-cost instruments whose communication can be facilitated by IoT technologies. In this chapter, we illustrate an example of an intelligent system for the integrated monitoring of the main landslide bodies of Gimigliano (CZ), southern Italy. The station includes clusters for monitoring deep movements and piezometric levels, as well as for urban structures through specific sensors and a network of sensors for topographic surface monitoring. The system was designed to be almost fully automatic and oriented to support near real-time warning activities. The data recorded by the deep and surface monitoring instruments confirm that the study area is affected by complex phenomena requiring long-term on-site monitoring. Specifically, analysis of the deep movements revealed some critical events during spring 2022 and summer 2023 that resulted in positive and negative millimetric deformations, measured by the tilt meters installed in correspondence with the monitored sites. Surface topographic analysis indicates displacement rates of 2.5–5 cm/year.
