GNGTS 2018 - 37° Convegno Nazionale

194 GNGTS 2018 S essione 1.2 On the basis of the corresponding seismogenic thickness we estimated the maximumwidth of possible master faults for some selected sectors along the two transects, taking into account also the prevailing tectonic regime and therefore selecting a dip angle consistent with the expected geometry of the structures ( i.e. ~30° for thrust faulting and ~50°-60° for extensional settings). We then calculated the maximum expected magnitudes M W for such structures, by applying the Wells and Coppersmith (1994) empirical relationships, considering both the regressions between fault width and M W , length (with a length/width ratio equal to 2) and M W and the rupture area-M W relationship. For the WSW-ENE transect we obtained maximum expected M W in the range 7.1-7.3 for the western sector (coastal area near Corfù), M W 6.6-6.8 for the central one (Kozani region), decreasing to values around 6.5-6.6 for the eastern portion in Fig. 3 - Thermo-rheological properties of the NNW-SSE trending transect: a) temperature depth distribution; b) maximum shear strength depth distribution; c) BDT depth variation along strike (yellow dashed line).
