FAULT MECHANICS - WHAT TRIGGERS EARTHQUAKES BY HADRIEN RATTEZ
Earthquakes are one of the most destructive natural disaster in terms of casualties and damages for infrastructures. The tools and technology developed in the last century have enabled to better characterize their location, depth and understand the conditions leading to a seismic slip. This increasing knowledge about earthquakes' nucleation enables to understand and try to prevent the seismic events induced by human activities (like gas extraction, water impoundment or fracking) and paves the way towards forecasting. In this seminar, the principal mechanisms leading to an unstable slip along faults will be presented with an emphasis on the role of thermo-hydro-chemo-mechanical couplings on their mechanical behavior. Experimental observations will be presented together with models to describe them.
