GNGTS 2015 S essione 1.1 By taking into account the slip historically observed in the field along the Moscarello fault and the PP2001 stress, we modelled the areal distribution of ∆CFS at a depth of 0.4 km as well as for three different sections crossing TFS (Fig. 3). In particular, we show two different computations considering faults that could be “encouraged” to slip, with dip-slip (Fig. 3a) and strike-slip kinematics (Fig. 3b), respectively. We observe that some faults, or parts of them, fall within lobes with increase of stress (red areas), where the rupture should be favored, while faults, or parts of them, that are located in areas in which the ∆CFS is negative (blue areas), are those potentially inhibited to slip. Also in this computation, we observe that the southern section of the S. Tecla fault, where the August 1865 earthquake nucleated, is characterized by a positive ∆CFS, confirming the observations inferred from the previous computation. These results, although preliminary, suggest that the August 19, 1865 earthquake could be potentially “triggered” by a stress transfers mechanism. Further tests on other case-histories might indicate if the stress transfer represents a common mechanism during faulting at Etna and therefore, provides useful constraints on the processes controlling it.
