Abstract

Recent efforts have been made to model the rupture process of large earthquakes in near-real time (NRT) in Chile. In this study, we propose an automated procedure using strong-motion data in an integrated system, which can characterize large earthquakes with a finite-fault model (FFM) in NRT. We developed several heuristic rules using the preliminary W-phase solutions to automatically set up the search ranges of the finite-fault inversions. The results show using strongmotion data and a W-phase magnitude, it is possible to obtain a rapid kinematic FFM in just a few minutes after the earthquake origin time.
