Abstract
We carried out new geological, morphotectonic, geophysical and paleoseismological investigations on the Meduno Thrust that belongs to the Pliocene-Quaternary front of the eastern Southern Alps in Friuli (NE Italy). The study area is located in the Carnic Prealps, where a series of alluvial terraces, linked to both climatic and tectonic pul...
Moulin and Benedetti (2018), https://doi.org/10.1029/2018TC004958 present a new interpretation of the Neogene‐Quaternary tectonic evolution of the Eastern Southern Alps (ESA) in Veneto‐Friuli. After the reinterpretation of literature field data by means of remote sensing analysis (Digital Elevation Model interpretation), they calculated deformation...
Interpretation of ENI industrial seismic lines, integrated with geophysical and morphotectonic data, allowed us to reconstruct the deep geometry, kinematics and Quaternary rates of the main blind thrusts in the northeastern corner of the Friuli Piedmont Plain. The study area is located in the eastern Friuli close to western Slovenia, where the fron...
In the framework of the III level Seismic Microzonation of the Pieve del Grappa municipality (Treviso, NE Italy), three paleoseismological trenches were dug, in order to investigate activity and capacity of the Crespano del Grappa backthrust.
The study area is located in the Veneto foothills, where the Plio-Quaternary external front of the Eastern...
The Matese area is located at the junction between Central and Southern Apennines. GPS data show NE-SW active extension with velocities across the area > 2 mm/yr. The area is characterized by a high seismicity and several seismic sequences were recorded even in recent times (1997-98 M<4.2, 2001 M<3.6, 2013-14 Ml 4.9, 2016 Mw 4.4). Despite the high...
By matching interpretation of seismic profiles of the Friuli pre-Alpin area with the surficial data collected during the detailed geological survey (CARG-FVG project), we have recontructed the deep arrangement of the Susans-Tricesimo thrust (which is considered the seismogenic source of the 6 May 1976 earthquake, Mw 6.45). The structural framework...

The zonation presented in this study has been developed with the aim of applying it as a branch of the logic tree that will be used for the new Italian seismic hazard map, presently in preparation according to the approach of seismotectonic probabilism. With respect to the zonation used for the present official seismic hazard map of Italy, the zona...
In May 2012, two earthquakes (Mw 6.1 and 5.9) affected the Po Plain, Italy. The strongest shock produced extensive secondary effects associated with liquefaction phenomena. Few weeks after the earthquakes, an exploratory trench was excavated across a levee of the palaeo-Reno reach, where a system of aligned ground ruptures was observed. The investi...
The study refers to the active slope deformation detected by GPS and tiltmeter stations in the Cansiglio
karstic plateau located in the western Carnic Prealps (NE Italy). The observed transient deformation clearly correlates with the rainfall, so that the southernmost border of the Plateau reacts instantly to heavy rains displaying a “back and fort...

The instrumental seismicity (earthquakes with 2.4.2.MD.2.5.6, collected by the Seismometric Network of the Friuli-Venezia Giulia Region) that hit the Italian-Slovenian border region in the period 1974-2000 was analysed and discussed. The study area, which is characterised by medium-high seismicity, is located in the north-eastern portion of the def...
The seismicity collected during the sequence that struck Friuli in 1976 and 1977 has been compared with that collected by the regional seismometric network in the following years (1977-1999). A standard approach was used to elaborate the seismological data recorded during the first year of the seismic sequence. A good quality data set of 479 hypoce...
The Funes Basin is an intermontane basin located in the northern Dolomites. At present, because of Neoalpine compressional tectonics, it is exposed for 2 km in a NE-SW direction and for about 3 km in an E-W direction. The basin is filled by up to 500 m thickness of andesitic lavas, which roughly thin eastwards and are replaced by up to 200 m of pyr...
On the 12th April 1998, a wide area in the middle valley of the Soča/Isonzo River near Bovec (NW Slovenia) was affected by an earthquake of MD = 5.6. It was followed by a long seismic sequence from which the 40 aftershocks, with MD ≥ 3.0 recorded until the 30th June 1998, have been analysed. The study area belongs to the External Dinarides: it is c...
