ERC St-G UNREST (2025-2030)
Principal Investigator: Małgorzata Chmiel
UNveiling dynamics of Rapid Erosion through advanced Seismic Techniques.
Floods and landslides are intensifying hazards, yet rapid erosion processes remain difficult to observe and predict. By developing a seismo–mechanico–hydrological approach, the UNREST project aims to monitor and anticipate these processes at high spatio-temporal resolution, providing new insight into the mechanisms that drive their transition to destructive events.
