Presentation Transcript

1. Damage coalescence controls slow and fast faulting: Insights from dynamic X-ray microtomography experimentsFrançois Renard, Jessica McBeck, Benoît CordonnierThe Njord Centre, Department of Geosciences, University of Oslo, NorwayISTerre, University Grenoble Alpes & CNRS, FranceHow does strain localization controls faulting ?Pre-existing slip surface: slow slips can generate damage in the volume around the fault, leading to catastrophic faulting.No pre-existing fault: microfractures accumulation leads to two end-member types of earthquakes. - fast earthquake - slow earthquakeRenard et al., Tectonophysics, 2020

2. Damage coalescence and slow faultingRenard et al., JGR, 2020

3. Damage coalescence influences the slow and fast behaviors of earthquake slipRenard et al. PNAS, 2019
