GNGTS 2017 S essione 1.2 115 Fig. 2 - Dashed black line: trace of the inferred faults by GPS profiles and field surveys; field and GPS-measured vertical offsets are reported (at white squares); yellow star locates the 1614 A.D. Tsaishi earthquake. (B) Steeply dipping strata, made of conglomerates of Late Miocene age, along the southern flank of the Tsaishi fold (42.395°N, 41.811°E). (C) Photo of river deposits tilted northward; location is provided by the blue dot (D) Example of river stream deeply entrenched immediately north of the fault scarp, i.e. in the hangingwall block. (E-F) Profiles across the fault scarps found at the foothills of the southern flank of the Tsaishi fold (central and SE part).
