Abstract:
Earthquakes arise from complex physical processes that couple frictional fault slip, stress accumulation, and fluid interactions across spatial and temporal scales. This seminar discusses recent advances in modeling fault behavior and rupture dynamics, integrating laboratory, field, and theoretical perspectives. We will explore how small-scale frictional processes influence large-scale earthquake patterns, the transition from stable sliding to dynamic rupture, and the role of pore fluids in fault weakening. These insights are critical for improving our ability to forecast seismic hazards and understand the physics underlying destructive earthquakes.
