This integrated system was developed to provide monitoring and early warning of extreme weather events through innovative land-based monitoring technologies. It combines two complementary subsystems: OS-IS© (Ocean Seismic – Integrated Solution) and SRS (Smart Rainfall System).

OS-IS© uses a triaxial accelerometer to detect micro-seismic vibrations generated by sea waves, allowing continuous monitoring of parameters such as significant wave height and wave period—without the need for offshore sensors. Installed on land and sheltered from marine conditions, OS-IS© offers a reliable and low-maintenance alternative to traditional buoy systems.

SRS introduces a novel approach to real-time rainfall estimation and short-term hydrogeological risk forecasting. By analyzing the attenuation of satellite TV signals received by a network of standard parabolic antennas, SRS produces high-resolution rainfall maps that highlight areas exceeding critical precipitation thresholds. When combined with a semi-distributed hydrological model, the system provides valuable insights into the potential impacts of heavy rainfall events.

To date, four OS-IS© stations have been installed along the Ligurian coast (Livorno, Bonassola, Genoa, and Andora), supplying continuous data on wave height and period. Additionally, five SRS stations (Genoa Val Polcevera, Bonassola, La Spezia–Strà, Livorno, and Andora) generate detailed rainfall maps for the monitored regions. Together, these systems form a robust and sustainable platform for improving coastal and hydrological risk management.
