Proceedings of the 12th International INQUA meeting on paleoseismology, active tectonic and archaeoseismology
210 PATA Days 2024 that normal faulting dominates in fault segments striking N‒S, whereas faults striking NE‒SW exhibit a sinistral strike- slip lateral component and normal faulting. Trench description The SCF-1 trench: This trench located in the SCF (Fig. 1A). The logged wall dimensions are ca. 9 m long and 3.5 m high next to the fault plane (Figure 2A). The trench wall exposes three colluvial wedge deposits termed CW1, CW2, and CW3 (Figure 2B). These colluvial units were generated by fault scarp degradation. The main fault dips 68° to the east and displaces the four oldest stratigraphic units of the trench (GS, FS, CW1, and CW2 in Figure 2B); CW3 seals the fault activity in the trench exposition. Synthetic and antithetic faults with respect to the main fault displaces GS, CW1 and CW2. The SCF in the trench site has accumulated ca. 6.2 m of along fault-dip displacement. Figure 2. SCF-1 trench. A) Geometry of the scarp at the northern wall of the trench. OSL ages are presented in black.b) Logging of the northern wall of trench SCF-1. c) Detailed view of the graben structure affecting units GS, CW1, and CW2.
