Snapshots of surface ruptures related to the largest foreshock at each site shown in Fig. 1c and/or Fig. 2. a Small cracks on an unpaved road, indicated by white arrows. After the mainshock, two fault traces and a small depression between them were identified here, as shown in Fig. 4b. b Three rupture traces with right-lateral offset of a paved road. Total amount of offset was several centimeters. Five rupture traces were identified here after the mainshock, as shown in Fig. 4c, d. Total amount of offset was 13–14 cm after the mainshock. c, d Cracks on a paved road, indicated by white arrows. No lateral offset was recognized. However, a fault trace with right-lateral offset of ca. 30 cm was identified here after the mainshock, as shown in Fig. 4e–g
