Fig. 1.From: An adjoint data assimilation method for optimizing frictional parameters on the afterslip areaPlate model domain used in this study. The thick rectangle is the fault area. The two shaded regions represent a large (LA) and small (SA) asperity, respectively. The region around the asperities is assumed to accommodate afterslip. The plate is subducting at a dip angle of 20°. The solid triangles with thin lines schematically show the trench.Back to article page
