Fig. 2

LOS displacements obtained by right- (a) and left (b)-looking InSAR images from ascending orbits. The statistics for these images are given in Table 1. The thick arrow shows the approximate direction of LOS vectors projected onto the horizontal plane. The thin arrow with a horizontal short line shows the approximate incidence angle. All InSAR images were flattened to reduce errors and unwrapped using the branch-cut algorithm to obtain the LOS displacement. The contour interval in LOS displacement is 10 cm. Cold and warm colors represent shortening and lengthening of the LOS displacement, respectively. The color scale saturates to black or white over 1 m in LOS change. The model fault traces for the inversion analysis are shown by red lines with ticks every 10 km. InSAR data in the area enclosed by the yellow lines are used in the inversion analysis
