    There is a typo in equation (8) of Patricelli et al. (2022). The isotropic-equi v alent luminosity observed at a viewing angle θj is (Salafia et al. 2015, 2019): (Equation Presented). where the relativistic Doppler factor δ appears to the power of three. This modification does not affect any of the results presented in Patricelli et al. (2022), that were obtained using the correct formula (equation 1) and not the one written in equation (8) of Patricelli et al. (2022). ACKNOWLEDGEMENT We thank Om Sharan Salafia for pointing out the typo in our manuscript

    CARATTERIZZAZIONE SISMOTETTONICA DELL'AREA DI GIUNZIONE TRA IL SUDALPINO E LE DINARIDI (NE ITALIA)

    L’attività tettonica recente del Friuli orientale è stata indagata tramite un approccio multidisciplinare. L’ara di studio, che comprende la Pianura Friulana orientale e il bordo Prealpino Giulio, rappresenta la zona di giunzione tra i fronti SSE vergenti della Catena Sudalpina e le strutture trascorrenti destre NW-SE del Friuli orientale e Slovenia occidentale. Attualmente, sia i dati GPS che sismologici mostrano che la deformazione che si accumula ad una velocità di 2-3 mm/a viene rilasciata dall’interazione tra faglie inverse e trascorrenti. Riguardo la sismicità, la distribuzione dei terremoti mostra che gran parte degli eventi è localizzata lungo l’arco alpino e prealpino e che almeno due terremoti forti (M>6) hanno colpito l’area di studio: il terremoto del 1511 (Mw 6.3) e la sequenza del 1976-1977 (Mw 6.0 events are documented: the 1511 Mw 6.3 earthquake and the 1976-77 sequence (Mw ≤ 6.4). In more recent times, the activation of the Raune strike-slip fault in western Slovenia caused the occurrence of two seismic sequences, in 1998 (Mw 5.6) and 2004 (Mw 5.2). With the aim to further explore the involvement of the active faults of eastern Friuli during the strongest seismic events occurred in the area, this work is focused on the recent activity of the tectonic structures. Following a multidisciplinary approach, the deep 3D-geometry of 4 main fault-systems were reconstructed by combining ENI seismic lines interpretation and hypocentral distribution analysis. Successively, a morphotectonic survey was conducted along the Julian prealpine border with the aim to detect the surficial anomalies related to tectonic activity. The collected morphotectonic hints allowed to define a NW-SE elongated zone of surficial deformation, highlighting the recent activity of the Colle Villano-N Thrust (CV-N) and the Colle Villano-Borgo Faris-Cividale trasnpressive Fault-System (CV-BFC). Based on the morphostructural results, two paleoseismological trenches were dug: the Fraelacco trench across the CV-N Thrust and the Campeglio trench across the CV Thrust. At Campeglio site, the excavated trench revealed the presence of paleoliquefaction features, thus suggesting that the area experienced seismic shaking. Differently, at Fraelacco site, the displacement of the Canodusso Subsynthem (21- 23 ka cal BP) allowed to identify two deformative episodes in the last 21 ka, with the latest likely occurred in historical times
