Fig. 7: Examples of surface ruptures and associated deformation measurements.

From: Surface rupture and shallow fault reactivation during the 2019 Mw 4.9 Le Teil earthquake, France

Fig. 7

a, d Field photographs showing surface ruptures affecting an asphalt road (flat pop-up structure) and a dirt road (extrados-fissures) (evidences # 7 and # 2, respectively, see location Fig. 4). b, e Ultra-high-resolution (1 mm) laser scans at the same locations. Blacks arrows in b correspond to profiles shown in c; red arrows in e points to N090–N100°E trending fissures (the two northeastern are those shown in d). The thin black lines correspond to the four topographic profiles shown in f. Note the position of cracks on top of what we interpreted as a 5 m long bulge affecting the dirt road. c, f Topographic profiles extracted from laser scans, showing the vertical components (the red dotted line in f corresponds to the suspected reverse-fault rupture controlling the bulge of the dirt road).
