Analysis of the Risk of Subsidence of Peripheral Archaeological Areas

In recent years, satellite EO (Earth Observation) technology has represented a primary source of geo-information to support national and local authorities and conservation institutions in managing and monitoring Heritage sites. Applications include preservation actions for valorization plans, sustainable tourism processes, buried features identification, as well as anthropogenic and natural risk monitoring such as looting and climate change effects on cultural landscapes, from early warning and rapid mapping to post-disaster analysis and damage assessment. The Copernicus Programme can play a big role in helping the process of monitoring cultural heritage sites and cultural landscapes as well as supporting their associated management.In the present study, we will investigate a specific consequence of climate change impacts on archaeological landscapes. In particular, the phenomenon of ground deformation and subsidence is addressed, focusing on Copernicus SAR data exploitation for multi-temporal monitoring of the archeological area of Gabii (Rome, Italy). In particular, the analysis focuses on the ground movement values through the EGMS (European Ground Motion Service) records and its temporal update using the on-demand ground motion services over the same area. The measured values are in line with the observed anomalies reported into the EGMS.
