The study of the hypocenter distribution of seismic events related to fault structures is a crucial topic since it is linked to the geological features and to the dynamics of an investigated area. The hypocenter spatial distribution of earthquakes is used in a novel algorithmic method to clusterize earthquakes to accurately identify the strike and...

The 1688 Sannio–Matese earthquake that struck the province of Benevento in Southern Italy on June 5 had a profound impact on the region. This seismic event caused extensive damage and significant environmental effects with I=XI Mercalli-Cancani-Sieberg (MCS) and Mw=7.0. Our study addresses a critical knowledge gap regarding the earthquake's environ...

With the continuous development of society, the rapid urbanization of cities, and the increasing construction of large-scale infrastructure projects, seismic hazard studies are becoming increasingly necessary [...]

The 1688 Sannio–Matese earthquake, with a macroseismically derived magnitude of Mw = 7 and an epicentral intensity of IMCS = XI, had a deep impact on Southern Italy, causing thousands of casualties, extensive damage and significant environmental effects (EEEs) in the epicentral area. Despite a comprehensive knowledge of its economic and social impa...

Damage induced by the 2016-2017 seismic sequence to building and infrastructural heritage in Central Italy was locally associated with the major evidence of surface faulting. This confirmed the relevant impact that surface faulting processes can have in urbanized areas and amplified the need to consider them in reconstruction planning, promoting Se...

We conducted large-depth Ground-Penetrating Radar investigations of the seismogenic Casamicciola fault system at the volcanic island of Ischia, with the aim of constraining the source characteristics of this active and capable fault system. On 21 August 2017, a shallow (hypocentral depth of 1.2 km), moderate (Md = 4.0) earthquake hit the island, ca...

More than forty years after the 23 November 1980 earthquake, which devastated the Campania and Basilicata regions, causing the destruction of a large number of towns and the death of around three thousand people, we have tried, through a large survey, to understand how and to what extent the urban fabric and the most affected communities have been...

Over the past two decades, the airborne Light Detection and Ranging (LiDAR) system has become a useful tool for acquiring high-resolution topographic data, especially in active tectonics studies. Analyzing Digital Terrain Models (DTMs) from LiDAR exposes morpho-structural elements, aiding in the understanding of fault zones, among other application...

Sediments infilling in intermontane basins in areas with high seismic activity can strongly affect ground-shaking phenomena at the surface. Estimates of thickness and density distribution within these basin infills are crucial for ground motion amplification analysis, especially where demographic growth in human settlements has implied increasing s...

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...

On 21 August 2017, a shallow earthquake of Md 4.0 struck the Casamicciola Terme village in the north of Ischia volcanic island (Italy). The earthquake has the typical characteristics of volcanotectonic events recorded at active volcanoes and occurred along the EW normal system fault bounding the northern slope of Mt. Epomeo. The epicentral area has...

A modern approach to the assessment of seismic hazard cannot disregard the study of effects induced by earthquakes in the natural environment. The knowledge and mapping of seismic-induced effects represent the basis for providing a more reliable and realistic scenario in territorial planning. In recent years this has been dramatically demonstrated...

The 26 December 2018 Mw 4.9 earthquake occurred at shallow depth (<1 km) on the eastern flank of Mount Etna and it was the strongest seismic event to hit this volcanic area during the past seventy years. The earthquake caused severe damage up to VIII degree EMS [Quest WG, 2019] and impressive surface faulting effects along the Fiandaca Fault (FF),...

In this article, we show why the geological model of the 21 August 2017 earthquake proposed by Nappi et al. (2018) has less uncertainty than the source model proposed by De Novellis et al.(2018). As a matter of fact, the Nappi et al. (2018) model takes into account all geophysical and geological information collected soon after the earthquake. On t...
