Laboratory simulations of slip behaviour in shallow subduction zones and landslides
Earthquakes and landslides represent serious geological hazards for human life, infrastructure, and the environment. Despite advances in surface monitoring technologies, our understanding of how different types of slip develop along faults—and their relationship with major earthquakes—remains limited, as does our ability to predict when a landslide will accelerate into catastrophic collapse.
Using sediment samples collected from both terrestrial and submarine landslides, as well as from faults in shallow subduction zones, this study conducted advanced laboratory experiments to replicate in-situ stress conditions and analyze how slip evolves in response to seismic shaking and increasing pore pressure.
The results provide new insights into the complex mechanical behavior of landslide and fault zone sediments, revealing how their strength properties can vary over time depending on their stress history. These findings are essential for improving predictive models of seismic and landslide hazards.
Speaker: Jonathan Carey
Biography:
Jonathan Carey studies the instability mechanisms of landslides and the behavior of faults in response to high pore-fluid pressures and seismic shaking. His research combines specialized laboratory testing, field monitoring, and remote sensing techniques to better understand fault movement and slope failure processes in both terrestrial and marine environments.
The event “Laboratory Simulations of Slip Behaviour in Shallow Subduction Zones and Landslides” will be held on Thursday, November 13, 2025, at 4:00 p.m., in Sala Albenga, DISEG, Entrance 1 – Politecnico di Torino.
