Short summary
We model fault-based seismicity rates by converting the slip rates of active faults into earthquake occurrence, considering both individual-fault ruptures and ruptures involving multiple adjacent faults. Our results show that multi-fault rupture scenarios better reproduce earthquake catalogues and paleoseismic observations, highlighting the importance of incorporating rupture complexity into future seismic hazard models.
