We revisited data related to the 1456 seismic crisis, the largest earthquake to have ever occurred in peninsular Italy, in search of its causative source(s). Data about this earthquake consist solely of historical reports and their intensity assessment. Because of the age of this multiple earthquake, the scarcity and sparseness of the data, and the unusually large damage area, no previous studies have attempted to attribute the 1456 events to specific faults. Existing analytical methods to… 

Fault delineation and stress orientations from the analysis of background, low magnitude seismicity in Southern Apennines (Italy)

The aim of this work was to show that refined analyses of background, low magnitude seismicity allow to delineate the main active faults and to accurately estimate the directions of the regional

Rise and Fall of a Hypothesized Seismic Gap: Source Complexity in the Mw 7.0 16 December 1857 Southern Italy Earthquake

Abstract On 16 December 1857, a strong earthquake ( M ∼7) struck a large portion of the southern Apennines about 150 km southeast of Naples. The earthquake was thoroughly investigated by Irish

A fresh look at the seismotectonics of the Abruzzi (Central Apennines) following the 6 April 2009 L’Aquila earthquake (Mw 6.3)

This work aims at providing an updated and augmented view of present-day tectonics and seismogenic sources of the Abruzzi Apennines, focusing on its extensional domain. This paper was spurred by the

Ranking Earthquake Sources Using Spatial Residuals of Seismic Scenarios: Methodology Application to the 1909 Benavente Earthquake

Historical earthquakes are of major importance in the analysis of seismic hazards, in particular for stable continental regions. In this article, we propose a methodology that uses seismic

In search of the seismogenic fault of the March 23rd 2018 earthquake (Mw 3.7) near Brindisi (Puglia, Southern Italy)

The portion of the southern Adriatic Sea, adjacent to the Murge area (Apulian Foreland, Southern Italy), is considered mainly aseismic. The recent March 23rd 2018 earthquake (Mw 3.7), occurred near

Detailed study of the seismotectonic setting in the Lucanian Apennines and surrounding areas (Southern Italy)

In this research work I analyzed the instrumental seismicity of Southern Italy in the area including the Lucanian Apennines and Bradano foredeep, making use of the most recent seismological database

The 2nd century AD earthquake in central Italy: archaeoseismological data and seismotectonic implications

The 2nd century AD earthquake in central Italy is only known by an epigraph that mentions restorations to a damaged weighing-house at the ancient locality of Pagus Interpromium. The available seismic

Do Strike-Slip Faults of Molise, Central–Southern Italy, Really Release a High Stress?

The 31 October and 1 November 2002 Molise earthquakes (both M w 5.7) were caused by right-lateral slip between 12 and 20 km depth. These earthquakes are the result of large-scale reactivation of



Seismology and Tectonic Setting of the 2002 Molise, Italy, Earthquake

Two Mw 5.7 earthquakes struck a sparsely populated region of southern Italy, on October 31 and November 1, triggering a swarm-like sequence that lasted for several days. The earthquakes were caused

Source analysis of the 2002 Molise, southern Italy, twin earthquakes (10/31 and 11/01)

On October 31, 2002, a moderate size earthquake (Mw = 5.8) occurred in Molise region, southern Italy, causing loss of young human lives in a school collapse and destructions in several villages. The

Defining seismogenic sources from historical earthquake felt reports

Abstract We present a method that uses macroseismic intensity data to assess the location, physical dimensions, and orientation of the source of large historical earthquakes. Intensity data contain a

Faulting mechanism and complexity of the November 23, 1980, Campania-Lucania Earthquake, inferred from surface observations

The lack of a well-recognized relation between large earthquakes and their surface effects in Italy has motivated the detailed reconstruction of the surface expression of the 1980 Campania-Lucania

A low magnitude seismic sequence near Isernia (Molise, Central Italy) in January 1986

Following the increase in seismic activity which occurred near Isernia (Molise, Central Italy) in January 1986, a digital seismic network of four stations with three-component, short-period

The investigation of potential earthquake sources in peninsular Italy: A review

We summarise and discuss almost a century of progress inthe understanding of the main characteristics of large Italian earthquakes.Topics of discussion include (1) the distribution of the largest

Areal Distribution of Ground Effects Induced by Strong Earthquakes in the Southern Apennines (Italy)

Moderate to strong crustal earthquakes are generally accompanied by a distinctivepattern of coseismic geological phenomena, ranging from surface faulting to groundcracks, landslides,
