Off-fault damage characterisation during and after experimental quasi-static and dynamic rupture in crustal rock from laboratory P-wave tomography and microstructures
Franciscus M. Aben, Nicolas Brantut, Thomas M. Mitchell
Elastic strain energy released during shear failure in rock is partially spent as fracture energy to propagate the rupture further. is dissipated within the rupture tip pro…

Fault reactivation by fluid injection: Controls from stress state and injection rate
François. X. Passelègue, Nicolas Brantut, Thomas M. Mitchell
We studied the influence of stress state and fluid injection rate on the reactivation of faults. We conducted experiments on a saw-cut Westerly granite sample under triaxial stress…

Assessing the efficiency of thermal pressurisation using natural pseudotachylyte-bearing rocks
Nicolas Brantut, Thomas M. Mitchell
The efficiency of thermal pressurisation as a dynamic weakening mechanism relies on the thermal and hydraulic properties of the rocks forming the fault core. Here, we assess the ef…
