“…17 km-long co-seismic ground ruptures along the western mountain-front of Mt Vettore from our field observations (for seismic source F4), previous works (e.g. Centamore et al, 1992;Blumetti et al, 1993;Galadini & Galli, 2000;Borre et al, 2003;Pizzi & Galadini, 2009) and published geodatabases (Basili et al, 2008;ITHACA, 2000), we preferred the focal mechanisms of INGV and USGS (Table 1; Fig. 12) for the geometric and kinematic attributes of seismic sources F3 and F4, respectively.…”

“…This means that the earthquake was strong enough to create new surface phenomena, while also being a triggering factor to already landslide prone areas further away. The basic philosophy for modelling the seismic sources is based on the Individual Seismogenic Sources (ISS) of DISS (Basili et al, 2008). Although most of the parameters are geologically, seismologically or even geodetically constrained, source dimensions sometimes cannot be directly defined.…”

“…The authors proposed northwestward rupture directivity, with nucleation just to the SE of Idrija. This hypothesis is also assumed by the Italian Database of Individual Seismogenic Sources (Basili et al, 2008). Nonetheless, as reported by Fitzko et al (2005), their model only partly reconciles the actual intensities suffered by many villages in Italy and Slovenia.…”

First evidence of active transpressive surface faulting at the front of the eastern Southern Alps, northeastern Italy: insight on the 1511 earthquake seismotectonics

Abstract. We investigated the eastern corner of northeastern Italy, where a system of NW–SE-trending dextral strike-slip faults of western Slovenia intersects the south-verging fold and thrust belt of the eastern Southern Alps. The area suffered the largest earthquakes of the region, among which are the 1511 (Mw 6.3) event and the two major shocks of the 1976 seismic sequence, with Mw = 6.4 and 6.1. The Colle Villano thrust and the Borgo Faris–Cividale strike-slip fault have been here first analyzed by interpreting industrial seismic lines and then by performing morphotectonic and paleoseismological analyses. These different datasets indicate that the two structures define an active, coherent transpressive fault system that was activated twice in the past two millennia, with the last event occurring around the 15th–17th century. The chronological information and the location of the investigated fault system suggest its activation during the 1511 earthquake.

“…The maximum expected magnitude in northern Italy and surroundings can be defined from "Catalogo Parametrico dei Terremoti Italiani (CPTI)" (Rovida et al 2011) and by the Database of Individual Seismogenic Sources (DISS) 3.1.1 (DISS Working Group 2010; Basili et al 2008). According to the seismogenic zonation of Italy, and the historical seismic events selected in the Italian macroseismic catalogs (e.g., Stucchi et al 2007;Locati et al 2011), the stronger historical events in the surrounding of the 2012 Emilia seismic sequence are: (1) the 1117 Mw = 6.7 Veronese earthquake; (2) the 1695 Mw = 6.5 Asolo earthquake; and (3) the 1920 Mw = 6.5 Garfagnana earthquake (Fig.…”

It has been observed that post-critically reflected S-waves and multiples from the Moho discontinuity could play a relevant role on the ground motion due to medium to strong size earthquakes away from the source. Although some studies investigated the correlation between the Moho reflections amplitudes and the damage in the far field, little attention was given to the frequency content of these specific phases and their scaling with magnitude. The 2012 Emilia seismic sequence in northern Italy, recorded by velocimetric and accelerometric networks, is here exploited to investigate Moho reflections and multiples (SmSM). A single station method for group velocity-period estimation, based on the multiple filter technique, is applied to strong motion data to detect SmSM. Amplitude and frequency scaling with magnitude is defined for earthquakes from Mw = 3.9 to Mw = 5.9. Finally, the ability of SmSM to affect the ground motion for a maximum credible earthquake within the Po plain is investigated by extrapolating observed engineering parameters. Data analysis shows that high amplitude SmSM can be recognized within the Po plain, and at the boundaries between the Po plain and the Alpine chain, at epicentral distances larger than 80 km, in the period range from 0.25 to 3 s and in the group velocity window from about 2.6 to 3.2 km/s. 5 % damped pseudo-spectral accelerations at different periods (0.3, 1.0 and 2.0 s), and Housner intensities, are obtained from data characterized by large amplitude SmSM. A scaling relationship for both pseudo-spectral accelerations and Housner intensities is found for the earthquakes of the 2012 Emilia seismic sequence. I MCS from VII to VIII is estimated, as a result of SmSM amplitude enhancement, at about 100 km for a maximum credible earthquake (Mw = 6.7) in the Po plain, showing that moderate to high damage cloud be caused by these specific phases.
