Session 1.1 - POSTER GNGTS 2023 Discussion and conclusions The morphotectonic evidence clearly shows that the growing of the fault and fold systems control the landscape evolution between the Kruja thrust front and the coastline. Very steep and rectilinear fault scarps are associated with the major NW-SE striking thrusts and backthrusts running with lengths reaching 50 km along the Kruja mountain front and the edges of the Durrës and Vora Hills. Fluvial diversions, dammed drainages and wind gaps are clear evidence of the ongoing compressional regime. Shortening and uplift result from the activity of major deep-seated and seismogenic thrust structures that induce the passive movement of the folds and thrusts observed at surface. The obtained results contribute to a better understanding and characterization of the inland many potential seismogenic sources in the region. So far, with the exclusion of the last Durres event likely caused by the Durrës Offshore Thrust (Vittori et al. 2021), none of the known major seismic events has been attributed with certainty to a specific fault source. A major effort, based also on paleoseismological studies, is required to significantly improve the current seismic hazard estimates, which must include also the hazardous effects of coseismic phenomena, such as surface faulting, landsliding, liquefaction.
