“…The case study fits particularly with the aim of the research because the complex phenomenon involves structures, infrastructures, the town of Petacciato, its cultural heritage, and the slope. Several studies [42][43][44] have been carried out highlighting the complexity of the landslide kinematics.…”

The development of innovative EWS, SHM and SHMR Systems is essential to prevent the occurrence of potentially dangerous events on engineering works, buildings and in the natural environment. Their effectiveness can be improved by using new generation sensors able to realize widespread, low-cost monitoring at increasing spatial and temporal resolution. The main aim of the research is, therefore, to develop a versatile strain transducer capable of monitoring elements of different nature such as slopes, buildings and linear infrastructures performing distributed real-time measurements. The paper introduces a New Smart Hybrid Transducer (NSHT), a strain transducer belonging to the Distributed Optical Fiber Sensors (DOFS) family, appositely designed to overcome the drawbacks of traditional solutions. An experimental laboratory setup was arranged to test its reliability and a comparison between measurements retrieved by the NSHT and traditional devices were done. The results showed that the NSHT is able to perform strain monitoring with spatial resolution as high as 5cm and accuracy comparable to that of the traditional devices. Finally, an ISGMS (Integrated Structural and Geotechnical Monitoring System) architecture based on its use is proposed for the Petacciato site, where a deep-seated landslide affects the historical town and some infrastructures. To realize a single communication line in such a complex monitoring system, where multiple elements have to be monitored, a specific tool was also designed and tested, that allows the exact spatial identification of the various elements under observation. Although on-site validation is needed, these early results are encouraging and demonstrate that the NSHT is a low-cost transducer with great potential and that, looking forward, it can be used to increase the effectiveness of the existing EW, SHM and SHMR Systems. The development of systems involving NSHT also follows the new approach to innovation policy contributing to different points of the 2030 Agenda.

In the past years due to climate change the region of South‐East Europe is subjected to extreme weather events with intense rainfall fallowed by activation or reactivation of landslides. In this paper a rainfall‐triggered landslide is investigated on extreme precipitation estimates. Hence, the behaviour of the slope is controlled by the hydro‐mechanical conditions and soil‐atmosphere interaction. In this case study a slope stability of a natural landslide is calculated for projected rainfall of 10 mm/h with 24‐hour duration. In such scenarios due to the excess pore‐water pressure even deep‐sited landslides beside local can exhibit global instability. This study aims to quantitatively assess the impact of intense rainfall on the landslides. The extreme precipitation pattern is considered as loading condition in a fully coupled hydromechanical finite element simulation, where the displacements, matric suctions, and suction stresses are calculated. The results indicate that intense rainfall leads to fast pore‐water pressure build‐up resulting in local strength reduction of the slope. In general, the findings urge to reassess the existing risk maps with more detailed models and higher prognosed precipitation.

Testing innovative procedures and techniques to update landslide inventory maps is a timely topic widely discussed in the scientific literature. In this regard remote sensing techniques – such as the Synthetic Aperture Radar Differential Interferometry (DInSAR) – can provide a valuable contribution to studies concerning slow-moving landslides in different geological contexts all over the world. In this paper, DInSAR data are firstly analysed via an innovative approach aimed at enhancing both the exploitation and the interpretation of remote sensing information; then, they are complemented with the results of an accurate analysis of survey-recorded damage to facilities due to slow-moving landslides. In particular, after being separately analysed to provide independent landslide movement indicators, the two datasets are combined in a DInSAR-Damage matrix which can be used to update the state of activity of slow-moving landslides. Moreover, together with the information provided by geomorphological maps, the two datasets are proven to be useful in detecting unmapped phenomena. The potentialities of the adopted procedure are tested in an area of southern Italy where slow-moving landslides are widespread and accurately mapped by using geomorphological criteria
