In order to improve knowledge on geometric, kinematic and seismotectonic characteristics of the active faults in Friuli, we achieved new morphotectonic and paleosesimological studies. We present the results of three trench excavations recently Fig. 1 - Structural sketch map of the eastern SouthernAlps and western Slovenia (modified from Zanferrari et al. , 2013). Black stars indicate the paleoseismological trench-sites.
