We focus on the coseismic surface faulting exposed along the Mt. Vettore-Mt. Bove fault system (VBF, central Italy), that activated during the 24 August 2016, Amatrice earthquake (Mw 6.0) and soon after reactivated during the 26 October Visso (Mw 5.9) and 30 October Norcia events (Mw 6.5 mainshock). We systematically recognized the coseismic surfac...

We present the results of a field survey performed in the central-northern portion of the Mt. Vettore – Mt. Bove normal fault (VBF), reactivated during the 2016 central Italy earthquake sequence (24 August, Mw 6.0; 26 October Mw5.4 and Mw 5.9; 30 October Mw 6.5). The field survey was carried out by means of digital mapping techniques, and tradition...

Fault displacement is a localized source of hazard for infrastructure located near active and capable faults, such as critical buildings and distributed facilities. This issue can be overcome through zoning and avoidance strategies, but facilities may sometimes not benefit from this option. In the last 20 years, several authors have developed a pro...

On 29 December 2020, a shallow earthquake of magnitude Mw 6.4 struck northern Croatia, near the town of Petrinja, more than 24 hours after a strong foreshock (Ml 5). We formed a reconnaissance team of European geologists and engineers, from Croatia, Slovenia, France, Italy and Greece, rapidly deployed in the field to map the evidence of coseismic e...

The occurrence of coseismic surface ruptures along fault traces in urbanised areas creates a serious hazard to the vulnerability of man-made manufactures. In order to mitigate such hazard, it is necessary to investigate the geometry, the activity and the capability of faults located close to urbanised areas. This paper presents a case study of the...

Geodetic benchmark displacement measurements following the 2020 Petrinjaearthquakein Croatia.

The 29 December 2020, Mw 6.4 Petrinja earthquake nucleated at a depth of~10 km in the Sisak-Moslavina County in northern Croatia,~6 km WSW of the Petrinja town. Focal mechanisms, aftershocks distribution, and preliminary Sentinel-1 InSAR interferogram suggest that the NW-SE right-lateral strike-slip Pokupsko-Petrinja fault was the source of this ev...
