Robust Imaging of Fault Slip Rates in the Walker Lane and Western Great Basin from GPS Data Using a Multi-Block Model Approach

Abstract

1. We estimate Walker Lane fault slip rates using a dense filtered and gridded geodetic velocity field and a robust multi-block model approach 2. The geodetic slip rates are independent of geologic slip rates, but 80% agree with them to within uncertainties 3. The method images off-fault deformation and vertical axis rotations providing more insight into how crustal motion drives earthquakes
