Short summary
Moderate to strong earthquakes commonly produce surface faulting, either along the primary fault or as distributed rupture on nearby faults. Hazard assessment for distributed normal faulting is based on empirical relations derived almost 15 years ago. In this study, we derive updated empirical regressions of the probability of distributed faulting as a function of distance from the primary fault, and we propose a conservative scenario to consider the full spectrum of potential rupture.
