Durante this case, the rift margin is marked by the occurrence of many faults with limited vertical displacements in the order of a few tens of meters, giving rise esatto a smoother topography with respect preciso what was observed mediante the northernmost transect
4 mm/yr for this structure. The occurrence of ignimbrites along the fault plane favored the formation of kinematic indicators, whose inversion resulted durante per roughly ESE-WNW direction of extension (Figure 7a). Similarly, sites 10 and 11 are characterized by magnificent exposures of fault zones; at site 10, radiometric dating of faulted debris resulted durante ages of 12,411 ± 100 and 13,902 ± 100 years B.
60 m. Again, inversion of kinematic indicators on the fault resulted in per roughly E-W preciso ESE-WNW direction of extension (Figure 8). Overall, analysis of fault slip tempo collected on faults along this transect shows verso strong coherence of momento (sites 8, 9, 10, 11, and 13) durante terms of tensione orientation, with the only exception of site 12 located at the northern termination of verso small horst (Figures 3 and 6; supporting information).
The central transect (ciclocross section B durante Figure 6) is located mediante correspondence puro the volcanic centers of Damota and Hobitcha. The faults are always very steep and dip esatto the Se, whereas con the more axial portions of the rift, they show verso consistent northwestern dip (Figure 6). The faults affect the Pleistocene volcano-sedimentary successions (Qvs), as well as the widespread Quaternary basalts (Qb2), whose emplacement is strongly linked puro the fault activity (see below; Figures 2, 5, and 6).
