The PhD will be hosted at the Laboratoire Interdisciplinaire de Physique (LIPhy, Université Grenoble Alpes/CNRS), in Grenoble, and carried out in close collaboration with the Institut des Sciences de la Terre (ISTerre, Université Grenoble Alpes/CNRS). The researcher will join the MODI team (Soft Matter, Organization, Dynamics and Interfaces) in LIPhy, under the supervision of Elsa Bayart and work with the Fault Mechanics and Instabilities team at ISTerre, under the supervision of David Amitrano and Jérôme Weiss. Description of the project . Earthquakes occur when faults suddenly slip and release accumulated stress. Understanding how this slip starts, propagates and radiates seismic energy is essential for earthquake physics and for improving seismic hazard assessment. In natural earthquakes, source parameters such as rupture length, stress drop and radiated energy are inferred from remote seismic measurements. Laboratory experiments offer a unique opportunity to overcome the lack of direct access to fault-scale rupture processes in natural earthquakes. They allow physical quantities to be measured directly on or near the fault while simultaneously acquiring non-local acoustic data, enabling direct validation of the relationships between local fault-scale parameters and seismic observables. Here, we propose to establish a quantitative link between local
