o detect earthquakes and pick phase arrivals with the deep-learning EQTransformer method (Mousavi et al 2020), and b) implement a Bayesian algorithm to derive earthquake locations that are robust against uncertainties associated with observations (phase picks) and velocity models. The updated catalog comprises 152% more events than the SCSN catalog in the study region around the SJFZ. The revised processing procedure, an overview of the new catalog, and select structural features observed in the catalog will be presented in the meeting.
