However, no systematic attempt has been made compare observed synthetic strains rotations demonstrate effectiveness techniques predicting these motions. Such a comparison is presented article earthquake, which occurred on San Andreas fault was recorded dense network instruments. Estimates are obtained applying time‐dependent geodetic analysis displacement time histories U.S. Geological Survey Parkfield Seismic Array (UPSAR) Turkey Flat array. A forward ground‐motion earthquake performed crustal models available literature, translational motions, strains, selected stations. computations carried out discrete wavenumber representation method generalized transmission reflection coefficient technique. motions generally good agreement with borehole volumetric array‐derived rotations, finite‐difference approximated gradients both frequency domains. results indicate that numerical simulations based kinematic source can be an effective tool characterizing region. further research necessary explore whether approaches classical linear elasticity theory sufficient predict major earthquakes. In addition, effect lateral heterogeneities, nonlinear soil response, failure, liquefaction should investigated. You do not access content, please speak institutional administrator if you feel access.
