Fig. 5

Principal stress directions and the principal strain observed over 5 years by Nakao et al. (2005). The principal stress map is the same as in Fig. 4a. The vector of the principal strain is plotted as shown in the legend. Arrows in a yellow circle on the map denote the direction of typical principal strain at the location of the circle. Stress, strain, and active faults at the points with numerals on the map are plotted at the left of the map to show their directions in detail
