TECTONIC FEAR Seminar by Valère Lambert

Описание: Title: Understanding fault failure processes: Bridging insight from the lab and field using physics-based modeling
Date: 16 February 2026

Zoom AI Summary: Valère Lambert presented research on fault failure processes and earthquake dynamics, focusing on how frictional resistance varies with sliding rate and history through physics-based numerical models. The research explored how dynamic weakening mechanisms like thermal pressurization can dramatically reduce shear resistance during fast slip, leading to spatially variable stress conditions and motion patterns. Valere Lambert and colleagues discussed how these findings could explain observed earthquake distributions and the complex relationship between slow and fast slip on faults, suggesting that faults may appear stable in the short term but remain critically stressed and susceptible to large earthquakes.
