RESEARCH ACTIVITIES (2019-2022)

The research activity of our geology research group here at the University of Udine is currently focused on the active tectonics of the Venetian-Friuli prealpine area (NE Italy). Particularly, our research topics include interpretation of seismic lines, seismicity distribution analysis, morphotectonic analysis, geologic and morphostructural field surveys and paleoseismological investigations. In this context, the 3D Move Software reveals very helpful to manage and elaborate the data we collect and allows us to reconstruct the 3D seismotectonic model which integrates geological, geophysical and paleoseismological data of the investigated tectonic structures.

2019: Reconstruction of the 3D structural model of the eastern Friuli Plain. Thanks to ENI cooperation, enabled by the Friuli Venezia Giulia Region, we were able to interpret more than 200 km of seismic lines (supplied in jpg format) covering an area of about 6000 km2 of the eastern Friuli Plain. By converting the interpreted seismic sections from time to depth we reconstructed the 2D geometry of the main stratigraphic horizons and tectonic structures. In a second step we elaborated the 3D geometry of the main fault systems by interpolating the fault lines drawn on each section.

2020: Reconstruction of the 3D structural model of the Susans-Tricesimo Thrust System (NE Friuli Plain). Thanks to ENI cooperation, enabled by the Friuli Venezia Giulia Region, we were able to interpret more than 200 km of ENI seismic lines. Through the 3D Move software, we reconstructed the 3D surface geometry of the Susans-Tricesimo Thrust System, which is considered the source of the 1976 earthquake. Moreover, the hypocentral distribution of earthquakes occurred in the latest 50 years was analyzed through the construction of seriated sections, with the aim to analyze the seismogenic potential of the investigated structure.

2021 ACTIVITIES: Seismotectonics of the Valdobbiadene-Xxxxxxxx Veneto Thrust, eastern Southern Alps. During the last two years, in the framework of the Progetto di Microzonazione Sismica III livello, we realized 12 paleoseismological trenches in the Venetian Prealpine region. We digitalized in 3D Move the logs of the studied wall trenches on vertical sections. In a second stage, the restoration of the log sections allowed us to characterize the recent activity of the fault in terms of number of deformational events and slip per event. Furthermore, the comparison of the distinct trenches intersecting the same tectonic structure at different points was useful to characterize the recent activity of the tectonic structure also along its length.

2022 ACTIVITIES: reconstruction of the 3d structural model of the Arba-Ragogna Thrust System (NE Italy) and definition of the seismogenic volumes for the estimation of the seismogenic potential of the area.

Starting from the interpretation of seismic lines, gently supplied by ENI, we realized 6 geological cross sections of the carnic prealpine bordering area and we reconstructed the 3D geometry of the investigated active thrust system: the Arba-Ragogna TS.

Aiming at the characterization of the seismogenic potential of the area, in terms of maximum potential magnitude (Mmax), we created and computed the geological volumes possibly corresponding to potential seismogenic volumes. We validated our results comparing the estimated Mmax values with the Italian Macroseismic Database (DBMI15 v4.0). The resulting good match highlights that the definition of the seismogenic volumes deserves to be further investigated since it can represent a new and alternative approach for the seismic hazard assessment of an area.
