Abstract

After more than forty years since the 1980 Irpinia-Lucania earthquake, with this Special Issue "The 23 November 1980 Irpinia-Lucania, Southern Italy Earthquake: Insights and Reviews 40 Years Later" we revisit this milestone geological and seismological event, bringing together the latest views and news on this earthquake, with the aim of improving the dissemination of wide-ranging information on this remarkable case history. This earthquake struck Irpinia-Lucania region (Lucania is also called Basilicata; Southern Italy) on 23 November 1980 (Ms 6.9, Io X MCS) [1,2], and it is remembered in Italy not only for being the strongest earthquake recorded in the last 100 years causing devastation of entire regions and severe loss of human life, but also for the destruction of the cultural heritage in the epicentral area. It was felt throughout Italy, from Sicily in the South, to Emilia Romagna and Liguria in the North (Figure 1) causing damage in over 800 localities spread in the regions of Campania and Basilicata with a total of 75,000 houses destroyed and 275,000 seriously damaged. The number of victims was about 3000

Abstract

As supplementary material we propose a publication, in which there is the first preliminary attribution of macroseismic intensity for the 1980 earthquake: "Il terremoto del 23-11-1980. Rilievo Macrosismico Stato di Avanzamento al 27-1-1981" [29] and some topographic maps of the effects induced by the 1980 IrpiniaLucania earthquake, which were plotted in the field. Soon after the November 23, 1980 Irpinia - Lucania earthquake, several groups of geologists of the CNR-PFG projects, mapped the coseismic geological effects in a wide portion of the epicentral area. We include some of the original sketch of topographic maps (form 1:25.000 topographic maps of Istituto Geografico Militare, I.G.M., 1955) saved as a historical record of the time, that the Professor Paolo Scandone, as leader of PFG project, made available many years after the earthquake on which the coseismic effects of the 1980 earthquake were mapped. On the excerpts of the topographic maps mainly earthquake-induced fractures are shown, and in some cases it has been marked occurrence of landslides as well as portions of earthquake-induced faults. Although it must be pointed out that many researchers at the time did not believe that these faults were of tectonic origin but ascribed all of them either to pure gravitative sliding or to debris compactation [11]. Only a few Italian researchers interpreted as due tectonic origin the fractures occurred along the Piano di Pecore on Mt. Marzano (186 Colliano IISW), or Sele Valley and at Pantano di S. Gregorio Magno (198 Buccino, I, NE; 199 Vietri di Potenza, IV, NW) [9,10], as later documented by several researchers who reconstructed the end to end seismogenic fault segments [12-17]. As supplementary material, the following are the cartographic union framework of the 1: 25,000 topographic maps attached and the extracts of these maps on which are mapped the coseismic effects detected during the field survey

Abstract

Our paper shows the preliminary results of a geophysical survey by the Ground Penetrating Radar (GPR) ultradeep "Loza 2N", in the study of buried active faults. This particular and innovative Georadar technique offers several advantages over the classic GPR techniques. Through low frequency antennas (10 MHz), it is possible to carry out deep stratigraphic studies down to about 400 m, thanks to: i) skipping of the stroboscope and cable connections between transmitter and receiver, ii) a direct digitalization of the signal, iii) the use of capacitive couplingWu-king antennas, iv) a 21 kV (20 Mwatt) transmitter. Furthermore, the latest development of the Loza receiver performed by RTG company allows using time windows up to 512000 nsec, scanning speed up to 1000/sec and stacking up to 100 tracks/sec. These characteristics make the GPR Loza different from most of the other GPR systems that can investigate, under optimal conditions, down to a maximum depth of about 30 m. Through the GPR Loza it is possible to identify, deep stratigraphic contacts and groundwater surfaces, faults and large fracture systems at depth. The Loza interpretative sections of the underground are fully comparable with those deriving from reflection seismics, which on the other hand require costs and acquisition and processing times far larger. In this work, the performances of the instrument are illustrated for identifying the active buried fault system that borders the western edge of the plain "Il Lago" (IS) at the foot of Mount Patalecchia in the Molise Apennines (Southern Italy), an area of high seismotectonic interest. The "Il Lago" plain closes the structure of the Bojano basin towards NW and is bordered by a direct buried fault system. Historically, the area was hit by strong earthquakes: the earthquake of December 5, 1456 (I = XI MCS; Mw = 7.2) which affected central and southern Italy; the earthquake of June 5, 1688 (I = XI MCS, Mw = 7.1) with the epicentral area in the Sannio, and the earthquake of July 26, 1805 (I = X MCS, Mw = 6.7), known as the earthquake of S. Anna whose epicentral area was the Bojano plain.

Abstract

We provide a database of the coseismic geological surface effects following the Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one of the strongest seismic events to occur in Europe in the past thirty years, causing complex surface ruptures over an area of >400 km2. The database originated from the collaboration of several European teams (Open EMERGEO Working Group; about 130 researchers) coordinated by the Istituto Nazionale di Geofisica e Vulcanologia. The observations were collected by performing detailed field surveys in the epicentral region in order to describe the geometry and kinematics of surface faulting, and subsequently of landslides and other secondary coseismic effects. The resulting database consists of homogeneous georeferenced records identifying 7323 observation points, each of which contains 18 numeric and string fields of relevant information. This database will impact future earthquake studies focused on modelling of the seismic processes in active extensional settings, updating probabilistic estimates of slip distribution, and assessing the hazard of surface faulting.

Abstract

We present a 1:25,000 scale map of the coseismic surface ruptures following the 30 October 2016 M-w 6.5 Norcia normal-faulting earthquake, central Italy. Detailed rupture mapping is based on almost 11,000 oblique photographs taken from helicopter flights, that has been verified and integrated with field data (>7000 measurements). Thanks to the common efforts of the Open EMERGEO Working Group (130 people, 25 research institutions and universities from Europe), we were able to document a complex surface faulting pattern with a dominant strike of N135 degrees-160 degrees (SW-dipping) and a subordinate strike of N320 degrees-345 degrees (NE-dipping) along about 28km of the active Mt. Vettore-Mt. Bove fault system. Geometric and kinematic characteristics of the rupture were observed and recorded along closely spaced, parallel or subparallel, overlapping or step-like synthetic and antithetic fault splays of the activated fault systems, comprising a total surface rupture length of approximately 46km when all ruptures were considered.

Abstract

The area of San Giuliano di Puglia (Southern Italy) was struck by a moderate earthquake of Mw=5.7 on October 31st, 2002. The aim of this study is to identify and constrain the geometry of the active structures in the area. We used an integrated analysis of geo-structural, seismological and gravimetric data in GIS environment. More specifically, we built three thematic databases: the “fault dataset” consists of the collection of tectonic structures extracted from different catalogues and scientific papers; the “earthquake dataset” contains the instrumental and historical earthquakes extracted from the available catalogues; the “gravimetric dataset” consists of lineaments identified by the Multiscale Derivative Analysis (MDA) maxima of the Bouguer anomaly map. The maxima of the MDA map highlight lineaments contacting lithologies with different density. A table of attributes associated with each type of data was created ad-hoc. Our analysis of the three thematic datasets at San Giuliano di Puglia showed a clear correlation between MDA lineaments and low-angle NW–SE thrust lineaments. Furthermore, there is a good correlation between the E–W re-localized San Giuliano di Puglia 2002 seismic sequence and a MDA maximum with E–W direction, without evidence of E–W surface mapped faults. Moreover, to define the geometry and depth extent of the active faults in the studied area, we have employed the Depth from Extreme Points method (DEXP) that produces an image of the source density distribution. Then we overlaid the DEXP image to the hypocenters section. The hypocenters section shows a sub-vertical plane, with the aftershocks tending to cluster between 12 and 16 km depth, well-correlated with sub-vertical DEXP maxima. Our outcome of a E–W active fault with sub-vertical plain suggests a possible correlation of it with the pattern of the sub-vertical buried extension of Mattinata fault system, having E–W direction. These results are in good agreement with the geological and scientific works supporting the activation of Mattinata fault in 2002.

Abstract

Since August 24, 2016 a destructive seismic sequence has been occurring in Central Italy, between the Amatrice and Norcia towns. The seismic sequence started with the event of Mw 6.0 that was followed one hour later by the Mw 5.4 earthquake and by thousands of aftershocks along the NW-SE fault system extended for about 30 km. On October 26 the Mw=5.9 seismic event struck the area, followed by the strong Mw 6.5 earthquake on the October 30, at a depth of 9 km with epicenter located between the Norcia and Visso towns. The three months of seismicity activated the nearby 60 km long normal fault system of Mt. Vettore - Mt. Porche - Mt. Bove. The area was struck by several moderate to large earthquakes in historical times. In detail, in the Amatrice sector we mention the earthquakes of 1627 (Io=7-8 MCS, Mw 5.3), 1639 (Io=9-10 MCS, Mw=6.2), 1672 (Io=7-8 MCS, Mw=5.3) A.D. The main historical earthquakes of Valnerina, the area closest to the epicentre of the October 30 2016 earthquake, occurred in 1328 (Io=10 MCS, Mw=6.5), 1719 (Io= 8 MCS, Mw=5.6), 1730 (Io =9 MCS, Mw=6) 1859 (Io=8-9 MCS, Mw= 5.7) A.D. It is important also to remember the complex sequence of the 1703 A.D. (January 14, Valnerina, Io=11, Mw= 6.9; February 2, Aquilano, Io 10, Mw= 6.7) that had a considerably devastating impact on the area. Nevertheless, the historical seismicity correlated with the more external fault system of the Umbria-Marche- Abruzzi Apennine ridge is characterized by absence of strong energy seismicity along the Mt. Bove - Mt. Vettore- Vettoretto sector, suggesting that the fault system was “silent” until the 2016 seismic sequence. Our study consists in a multiparametric data analysis in GIS (Geographic Information System) environment which integrates tectonic, seismic and gravimetric datasets with the aim of investigating the neotectonic activity of the area. The gravimetric dataset contains the Multiscale Derivative Analysis (MDA) data of the gravity field, in which each maximum corresponds to a density contrast at some depth or to topographic features.We have minimized the topography effects to make sure that the MDA maxima are related only to faults. We have analyzed the seismogenic structures and investigated the geometry of the main fault planes through a combined analysis of hypocentral sections and the DEXP (Depth from Extreme Points) results on gravity data. In this study, we have validated our method based on literature geological and geophysical data. This will allow us to employ our approach for investigating possible buried/silent active faults for contributing to the knowledge of the Apennine seismic hazard.

Abstract

This paper aims to present, through a photographic reportage, the current state of rebuilding of the most devastated villages by the earthquake that hit the Southern Italy on 23 November 1980, in Irpinia-Basilicata. The earthquake was characterized by magnitude Ml = 6.9 and epicentral intensity I0 = X MCS. It was felt throughout Italy with the epicenter in the Southern Apennines, between the regions of Campania and Basilicata that were the most damaged areas. About 800 localities were serious damaged; 7,500 houses were completely destroyed and 27,500 seriously damaged. The photographic survey has been done in 23 towns during the last five years: Castelnuovo di Conza, Conza della Campania, Laviano, Lioni, Santomenna, Sant’Angelo dei Lombardi, Balvano, Caposele, Calabritto and the hamlet of Quaglietta, San Mango sul Calore, San Michele di Serino, Pescopagano, Guardia dei Lombardi, Torella dei Lombardi, Colliano, Romagnano al Monte, Salvitelle, Senerchia, Teora, Bisaccia, Calitri and Avellino. Forty years after the 1980 earthquake, the photographs show villages almost completely rebuilt with modern techniques where reinforced concrete prevails. Only in few instances, the reconstruction was carried out trying to recover the pre-existing building heritage, without changing the original urban planning, or modifying it. We argue that this photography collection allows to assess the real understanding of the geological information for urban planning after a major destructive seismic event. Even more than this, documenting the rebuilding process in a large epicentral area reveals the human legacy to the natural landscape, and our ability, or failure, to properly interpret the environmental fate of a site.

Abstract

The aim of this study is to identify and constrain the geometry of the seismogenic structures (active, outcropping and buried fault systems) of the Abruzzo area (central Italy), through an integrated analysis of geo-structural, seismic and gravimetric data. We generated three thematic: “faults”, “earthquakes” and “gravimetric" data: i) The fault dataset consists of data extracted from the available structural and geological maps (ITHACA catalogue; the "Neotectonic Map of Italy" 1:500.000; several geological sheets 1:50.000 from ISPRA CARG project; the Geological Map 1:100.000 Sheet 1), and many geological studies. ii) The earthquakes datasets was created by merging the data from historical and instrumental Catalogues (CPTI04 and CPTI11; ISIDE - INGV). iii) The gravimetric datasets consists in the Multiscale Derivative Analysis (MDA) of the Bouguer anomaly map of the area, whose maxima show the presence of density lineaments. The merge of these datasets in GIS environment, highlighted four possible scenarios of correlation between faults, earthquakes and MDA maxima: 1) the existence of active faults, revealed by a strong correlation between epicentral location of seismic clusters, fault positions and MDA maxima; 2) the existence of buried active faults, highlighted by a good correlation between MDA maxima and epicentral positions, without correspondence with faults known from geological data; 3) the existence of inactive or silent faults, detected by the presence of faults reported in the geological datasets and literature which are associated with MDA maxima, without correlation of earthquakes; 4) the existence of faults not correlated with MDA maxima; this could be due to faults putting in contact two lithologies with a similar density. A comparison between seismic hypocentral locations and the fault geometry retrieved by DEXP analysis on gravity data was performed over some significant active faults of the area, such as the Paganica fault. Our analysis yielded new insights into the fault characteristics (dip direction and angle) and its activity.

Abstract

The area of San Giuliano di Puglia (Southern Italy) was struck by a moderate earthquake of Mw=5.7 on October 31st, 2002. The aim of this study is to identify and better constrain the geometry of the seismogenic structures (active, outcropping and buried faults) in the area. We used an integrated analysis of geo-structural, seismic and gravimetric data. We built three thematic databases: “faults”, “earthquakes” and “gravimetric" data: 1. The fault database consists of data extracted from the available structural and geological maps: ITHACA (ITaly HAzard from CApable faults) catalogue; DISS (Database of Individual Seismogenetic Sources) database; the "Neotectonic Map of Italy" 1:500.000; the Geological Map 1:100.000, Sheets 154, 155, 162, 163; several geological studies. 2. The earthquakes database was created by merging the data from historical and instrumental Catalogues (CPTI11; ISIDE-INGV). 3. The gravimetric database was created through the Multiscale Derivative Analysis (MDA) of the Bouguer anomaly map of the area, whose maxima show the presence of density lineaments. The integration of these datasets in GIS environment, identified three possible cases of correlation between faults, earthquakes and MDA maxima: ⦁ A clear correlation between epicentral location, fault positions and MDA maxima shows the existence of active faults; ⦁ A good correlation between MDA maxima and epicentral positions, without correspondence with faults known from geological data, can suggest the presence of buried active faults; ⦁ A good correlation between faults from geological datasets and literature and MDA maxima, without correlation with earthquakes, can indicate the existence of inactive or silent faults. Previous studies show that the main shock in the area of San Giuliano di Puglia was generated by a deep and subvertical strike-slip structure E-W trending, with a right lateral focal mechanism (Galli & Molin, 2004). Nevertheless, Vezzani et al. (2009) proposed a reverse fault mechanism. Valensise et al. (2004) suggested that the 2002 events could be related to the Mattinata fault, a major active right lateral strike-slip fault cutting across the Gargano promontory, In order to better constrain the structural framework of this area, we combined faults seismic data and a multiscale approach of gravity data in GIS environment.

Abstract

The aim of the study is to identify and better constrain the geometry of the seismogenic structures (active, outcropping and buried fault systems) in the Abruzzo area (central Italy), through an integrated analysis of geo-structural, seismic and gravimetric data. The studied area is one of the most active zones from a geodynamic point of view of the Italian Apennines, characterized by the occurrence of intense and widely spread seismic activity. The integrated analysis of structural, seismic and gravimetric data (Gaudiosi et al., 2012) of the areas was carried out through the use of Geographic Information System (GIS). More specifically, the analysis consisted of the following main steps: (a) collection and acquisition of aerial photos, numeric cartography, Digital Terrain Model (DTM) data, geological and geophysical data; (b) generation of the vector cartographic database and alpha-numerical data; c) image processing and features classification; d) cartographic restitution and multi-layers representation. Three thematic data sets have been generated: “faults”, “earthquakes” and “gravimetric” data. The fault dataset was built by merging all Plio- Quaternary structural data extracted from the available structural and geological maps, and many geological studies (Boncio et al., 2004; Galadini et al., 2000, 2003; Falcucci et al., 2011; Moro et al., 2013). The earthquake data set consists of seismic data collected in the available historical and instrumental Catalogues (Gruppo di lavoro CPTI, 2004); CPTI11, Rovida et al., 2011; ISIDE, INGV database). Seismic data have been standardized in the same format and merged in a single data set. As regards the gravimetric data set, we performed a Multiscale Derivative Analysis (MDA) of the gravity field, based on the good resolution properties of the Enhanced Horizontal Derivative (EHD) signal (Fedi et al., 2005). The main results of our integrated analysis show a good correlation among faults, epicentral location of earthquakes and MDA lineaments from gravity data. Furthermore, 2D seismic hypocentral locations were correlated with the information yielded by the application of the DEXP method to gravity data (Fedi and Pilkington, 2012), to estimate strike, dip direction and dip angle of some faults of the areas.

Abstract

On 24 August 2016, a Mw6.0 normal‐faulting earthquake struck central Italy, causing about 300 fatalities and heavy damage. A geological survey collected the coseismic effects observed at the surface in order to evaluate two competing hypotheses about their nature: surface faulting versus gravitational deformation. We find that the most significant geological effect is a 5.2 km long alignment of ground ruptures along the Mount Vettore Fault System. These ruptures are independent from lithology, topography, morphology, and change in slope and exhibit an average dip‐slip displacement of ~13 cm. Geometry, kinematics, and dimensional properties of this zone of deformation strongly lead us to favor the primary surface faulting hypothesis that fits well the predicted estimates from experimental scaling law relationships. Our study provides relevant hints for surface faulting in extensional domains, contributing to implement the worldwide database of the moderate earthquakes.

Abstract

In this paper we present the geological effects induced by the 2012 Emilia seismic sequence in the Po Plain. Extensive liquefaction phenomena were observed over an area of ~ 1200 km² following the 20 May, ML 5.9 and 29 May, ML 5.8 mainshocks; both occurred on about E-W trending, S dipping blind thrust faults. We collected the coseismic geological evidence through field and aerial surveys, reports from local people and Web-based survey. On the basis of their morphologic and structural characteristics, we grouped the 1362 effects surveyed into three main categories: liquefaction (485), fractures with liquefaction (768), and fractures (109). We show that the quite uneven distribution of liquefaction effects, which appear concentrated and aligned, is mostly controlled by the presence of paleo-riverbeds, out-flow channels and fans of the main rivers crossing the area; these terrains are characterised by the pervasive presence of sandy layers in the uppermost 5 m, a local feature that, along with the presence of a high water table, greatly favours liquefaction. We also find that the maximum distance of observed liquefaction from the earthquake epicentre is ~ 30 km, in agreement with the regional empirical relations available for the Italian Peninsula. Finally, we observe that the contour of the liquefaction observations has an elongated shape almost coinciding with the aftershock area, the InSAR deformation area, and the I ≥ 6 EMS area. This observation confirms the control of the earthquake source on the liquefaction distribution, and provides useful hints in the characterisation of the seismogenic source responsible for historical and pre-historical liquefactions.

Abstract

This paper deals with an interdisciplinary research that has been carried out to investigate the neotectonic activity of the Campanian plain and surrounding areas (southern Italy), affected by Plio-Pleistocene tectonics and volcanic activity. Three thematic data sets have been generated for this area, "fault", "earthquake" and "gravimetric" data sets, respectively. These data sets allow an integrated analysis of the structural, seismic and gravimetric data in GIS environment with the aim of identifying the active structural lineaments that accommodate the local stress through seismic activity. In detail, an original map with Plio-Quaternary tectonic structures of the Campanian plain and its margins, constrained by morpho-structural analysis and/or geophysical exploration data, is presented. The available earthquake data sets have been merged in a single data set, including seismicity in the Campanian area from 217 b.C. to 2010; processing of seismic data for new precise earthquake locations have been carried out for some clusters of events with poor data, for better constraining existence and activity of some outcropping and buried tectonic structures. As regards the gravimetric data set, a Multiscale Derivative Analysis (MDA) of the gravity field of the area has been performed, relying on the high resolution properties of the Enhanced Horizontal Derivative (EHD). MDA of gravity data allowed localization of several linear and close trends, identifying anomaly sources whose presence was not previously detected. Our integrated analysis shows that a strong correlation occurs among the new hypocentral locations of the seismic clusters matching the fault systems of the Massico Mt. and Avella Mts., and the MDA lineaments from gravity data relative to the same tectonic structures.

Abstract

The aim of this study is a critical revision of historical and recent seismicity of the Salento peninsula (Apulia, Southern Italy), offering an updated evaluation of its seismic hazard currently underestimated. This area is actually included in the least dangerous IV category of the Italian seismic classification. The Salento Peninsula was struck by the February 20, 1743 earthquake, considered as the strongest seismic event of this area. The reassessment of both the macroseismic effects on man-made structures, and the triggered effects in the natural environment has been carried out on the basis of archival documents and recent literature, according to the MCS and the ESI 2007 scale. The main result of our study has been the re-evaluation of the maximum intensity (Imax=XMCS) of the 1743 earthquake, besides new intensity values for some localities along the Apulian coasts.
