Fig. 13From: Adjoint-based direct data assimilation of GNSS time series for optimizing frictional parameters and predicting postseismic deformation following the 2003 Tokachi-oki earthquakeSpatial distributions of vθ/L and examples of the temporal evolution. The spatial distributions of vθ/L of a only when the frictional parameters are optimized, and b both initial values and frictional parameters are optimized. The temporal evolutions of vθ/L at subfaults c A and d B are indicated by blue and red lines, which correspond to the results of a and b, respectively. The locations of subfaults A and B are indicated in aBack to article page
