GUIDANCE: A New Situation for Near-Real-Time Monitoring of Surface Displacements in Landslides Hazard Overview

E& TC

We are presenting method for near-real-time monitoring of surface displacements due to landslide phenomena, namely Advance displacement monitoring system for Early warning (guidance). The procedure includes: (i) data acquisitions and transfer protocol; (ii) data collections, filtering, and validations; (iii) data analysis and restitution through a set of dedicated software; (iv) recognition of displacement/velocity threshold, early warning messages via SMS and emails; (v) automatic publication of the results on a dedicated webpage. We show how the system evolved and the results obtained by applying guidance over three years into a real early warning scenario relevant to a large earthflow located in southern Italy. guidance has speed-ups and facilitated the understanding of the landslide phenomenon, the communications of the monitoring results to the partners, and consequently the decision-making process in a critical overviews. Our work might have applications for landslide monitoring and in other contexts, as monitoring of other geographic hazards and of critical infrastructures, as open-pit mines, buildings, dams, etc.
