Figure 10. Vectorial comparison of pre-, co-, and post-seismic stresses (shear tractions) on the Nojima fault at the Hirabayashi and Ogura borehole sites. Circles: initial stress inferred from location 2 and 7 striations. Solid line: stress change vectors from the hybrid slip model. * and +: maximum post-seismic shear stress (SH-Sh)/2 from below and above the cataclastic zone, respectively, in the Hirabayashi borehole. x : maximum post-seismic shear stress from the Ogura borehole. Dashed lines: correction to shear taking into account fault normal compression. Results from both striation locations and the boreholes indicate complete stress drop.
