Constraining Fault Damage Zone Properties From Geodesy: A Case Study Near the 2019 Ridgecrest Earthquake Sequence

Seismologic studies have reported seismic velocities reduction and Vp/Vs ratio changes over damage zones associated with seismogenic faults. The structure elastic properties of these indicate the maturity faults affect rupture dynamics future events. Therefore, they contain critical information about fault that could inform hazards. Here we present a geodetic modeling approach to constrain velocity under stress perturbation from nearby earthquakes. Compared tomographic analysis is usually limited by resolution, this provides tighter constraints on geometry zone at shallow depths. Our results imply major component strain release distributed inelastic. existence numerous either may locally detached layer or are remnants earlier evolution.
