Laboratory Simulations of Slip Behaviour in Shallow Subduction Zones and Landslides

This 54-minute lecture explores the complex mechanics behind earthquakes and landslides through laboratory experiments. Discover how researchers at the University of Liverpool use advanced shear box testing on sediments collected from terrestrial landslides, submarine landslides, and shallow subduction zone faults to replicate field stress conditions and study slip development. Learn about the relationship between material behavior and movement responses that remain poorly constrained despite advances in earth surface monitoring. Gain insights into how strength properties of different sediment types vary through time due to stress history, influencing various styles of slip. The research findings presented contribute to improved earthquake and landslide hazard models by enhancing our understanding of when landslides might accelerate catastrophically and how different slip behaviors occur in fault environments.
