Short summary

The paper describes microstructures in granitic rocks located 50 m away from the Nojima fault in Japan. Although macroscopically undeformed, the sample displays evidence for intense dynamic damage at the microscopic scale. Elastic strain and high residual stresses stored in quartz grains suggest that they were produced by propagating rupture fronts associated with M6 to M7 earthquakes and contributed to the widening of the damaged fault zone along the Nojima fault during the Paleocene.
