Abstract

A nonlinear weighted least-squares inverse analysis was performed for a synthetic elastic layer over viscoelastic half-space model of strike-slip faulting, and an inversion of strain rate data was attempted for the locked portions of the San Andreas fault in California. A suite of inversions was performed for the San Andreas, holding recurrence time and locking depth fixed at particular values for each inversion. These inversions resulted in nearly the same data misfit. Inversions on data from the northern San Andreas resulted in predicted parameter ranges similar to those produced by inversions on data from the whole fault. The addition of observations which vary with distance from the fault should help to constrain these ranges, and perhaps allow resolution of recurrence time and locking depth. -from Authors
