Rainstorm-induced landslides are a widespread geomorphological hazard that can lead to major emergencies, causing severe damage to life and property. Due to the extent of the areas usually affected by these phenomena (up to thousands of km²) and/or their typical high areal density, in the early stages of the emergency it can be useful to reconstruc...

This study provides insights into the tectonic evolution of the normal Mt Morrone Fault System (MMFS) in Central Italy and highlights the utility of multidisciplinary approaches in reconstructing the seismic history of dormant fault systems. The MMFS comprises two parallel normal faults that traverse the western slope of Mt. Morrone, and although t...

Somma-Vesuvius, Campi Flegrei, and Ischia are three active volcanoes in the Neapolitan Area (Italy). In this work, we evaluated the combined tephra fallout hazard posed by the three volcanoes on a large-size (~600 km × 700 km) and high-resolution (~3 km) domain. In order to explore the effect of the intrinsic variability in eruption and wind condit...

Con questo volume, che fa parte della collana BookMS Manuali (download dal sito www. centromicrozonazionesismica.it), intendiamo raccogliere, organizzare e mettere in condivisione i principali elementi e insegnamentitratti dall'intensa attività svolta in questi ultimi due anni. In particolare, sono riportate indicazioni utili alle attività di racco...

Many large-magnitude faults (6.5≤ Mw ≤7.2) of the Italian Apennines are characterized by multi-century return times, so historical sources may have missed their last earthquake or other predecessors. Hence, even in Italy, where seismic catalogs are among the most comprehensive and time-extensive worldwide, there is a need for complementary studies...

Nowadays, modeling of tephra fallout hazard is coupled with probabilistic analysis that takes into account the natural variability of the volcanic phenomena in terms of eruption probability, eruption sizes, vent position, and meteorological conditions. In this framework, we present a prototypal methodology to carry out the long-term tephra fallout...

Nowadays, tephra fallout hazard is based on coupling the physical modeling of the tephra dispersion processes with a probabilistic analysis that takes into account the natural variability of the volcanic phenomena in terms of eruption probability, eruption sizes, vent position and meteorological conditions. In this framework, we present a prototypa...

Thirty‐two tephra layers were identified in the time‐interval 313–366 ka (Marine Isotope Stages 9–10) of the Quaternary lacustrine succession of the Fucino Basin, central Italy. Twenty‐seven of these tephra layers yielded suitable geochemical material to explore their volcanic origins. Investigations also included the acquisition of geochemical dat...

Ground motion modification over large areas is generally evaluated by focusing on source effects disregarding local lithostratigraphic site conditions. Hence, amplification maps of peak ground acceleration and peak ground velocity are proposed to improve the forecast of ground motion on a national scale. Topological information about litho-type suc...

Under seismic actions, underground cavities play a not negligible role for seismic site effect and, at the same time, they represent objects exposed to seismic risk. Thus, their possible instability up to the collapse could have effects on the above-ground structures and infrastructures, as revealed by recent and past earthquakes. In consideration...

Seismic liquefaction assessment at different geographical scales provides hazard maps at increasing levels of resolution and reliability. According to the considered level, the areas prone to liquefaction are identified based on specific predisposing and triggering factors, including geological and geotechnical subsoil properties and local seismici...

This work is part of a broader project that aims to define a methodology for assessing the local seismic response on a large scale through a series of cognitive phases. Here we present the first phase that illustrates a procedure for the creation of standardised geothematic maps, at a national, regional and sub-regional scale, showing the geologica...

We present the first evidence of surface rupture along the causative fault of the 14 January 1703 earthquake (Mw 6.9, Italian central Apennines). This event was sourced by the ~30 km-long, Norcia fault system, responsible for another catastrophic event in Roman times, besides several destructive earthquakes in the last millennium. A dozen paleoseis...

The effects induced by the choice of numerical base conditions for evaluating local seismic response are investigated in this technical note, aiming to provide guidelines for professional applications. A numerical modelling of the seismic site response is presented, assuming a one-dimensional scheme. At first, with reference to the case of a homoge...

We investigated the late Upper Pleistocene activity of the eight main faults that comprise the active, dip-slip Gran Sasso fault system (GSFS) in the Gran Sasso d'Italia Massif (central Italian Apennines; 2912 m a.s.l.). We carried out novel paleoseismological analyses at four sites of three different fault segments, and reviewed the data of the pr...

The availability of a unique database, where all data of the seismic microzonation studies carried out in about 1900 municipalities of Italy (https://www.webms.it/) are achieved with a standardized format, allowed statistical elaborations in terms of subsoil parameters. In particular, we analysed borehole logs and geophysical data in order to chara...

The Seismic Microzonation studies (SMs), promoted all over the Italian territory by the Department of Civil Protection, provide fundamental knowledge of the subsoil response in seismic conditions at the urban scale. Amplification phenomena related to lithostratigraphic and morphological characteristics, instabilities and permanent deformations acti...

The seismic subsoil response in terms of amplification or attenuation of the ground motion is the result of a complex combination of factors, including the vertical and horizontal subsoil heterogeneities (Fabozzi et al., 2021). In volcanic areas in particular, the vertical subsoil heterogeneities are well identified by characteristic superposition...

Prediction of surface ground motion based on advanced approaches is a non-trivial task at large area. In fact, advanced approaches require a detailed geological and geotechnical subsoil model based on geological, physical and mechanical properties retrieved from in situ investigations and laboratory data, and to perform time consuming numerical sim...

Evaluation of bedrock stiffness and thickness effect on ground motion modification represent a key-issue in the perspective of seismic risk reduction policy, since the maximum depth of site prospection generally does not extend down to the stiff bedrock location. Site conditions were identified from the Italian database of seismic microzonation stu...

One of the most important controlling parameters of the seismic site response in terms of earthquake ground motions modification is the shear wave velocity (Vs) profile of the subsoil, that generally increases with depth because of geological age, cementation and overburden stress. There exist, however, geological settings where the velocity profil...

In this study, we derive a large-scale Vs30 map for Italy starting from the global terrain geomorphological classification based on normalized slope, local convexity, and surface texture (after Iwahashi et al., 2018). The novelty of the present work is the integration of a large amount of data from the Italian seismic microzonation dataset, consist...

Total seismic hazard assessment (i.e. the base hazard modified by local site conditions) plays a key role in seismic risk prevention and mitigation. This is an important topic due to the impact of a reliable hazard as- sessment on the resilience of local communities in the case of an earthquake. This paper presents a study that evaluates the total...

In dry loose sand, seismic cyclic loads can result in contractive volumetric strains (seismic densification or compression) that can induce damages to structures, infrastructures and lifelines, accordingly with post-earthquake damages of past events. In the present work, a procedure has been adopted to define simplified charts to predict the possib...

The shear wave velocity, Vs, profile of the subsoil is one of the most important controlling parameters of the seismic site response (Rathje et al., 2010), i.e. the motion modification during the wave propagation through the stratigraphic series, from the bedrock upward to the ground surface. Despite the high heterogeneities and complexities of the...

Il lavoro è il risultato di analisi statistiche condotte su alcuni parametri archiviati nella banca dati nazionale della microzonazione sismica (di seguito DB-MS, disponibile per la consultazione su www.webms.it, realizzato da CNR IGAG per il Dipartimento della Protezione Civile nazionale), derivanti dalle indagini raccolte negli studi di microzona...

Seismic microzonation studies (hereafter SMs or SM studies) have a strategic application in land use planning in the perspective of territory protection. At urban scale, SMs are finalized to forecast the spatial distribution of stratigraphic and topographic local amplification effects of ground motion and the co-seismic instabilities such as landsl...

In dry loose sand, seismic cyclic loads can result in contractive volumetric strains (seismic densification or compression) that can induce damages to structures, infrastructures and lifelines, accordingly with post-earthquake damages of past events. In the present work, a procedure has been adopted to define simplified charts to predict the possib...

The Mount Vettore normal fault ruptured between August and October 2016, sourcing three earthquakes of Mw 6.2, 6.1, and 6.6. The first one caused the death of 299 people, while the entire sequence reached the highest macroseismic intensity levels in Italy since the catastrophic 1915 Fucino event (Mw 7.1). This fault was known to be one of the histo...

A 1:5,000 scale geological map and 31 geological cross-sections are presented for the surroundings of Amatrice village (central Apennines, Italy), epicentral area of the first damaging earthquake of the 2016–2017 seismic sequence. This detailed geological dataset focuses on: (i) the extent, the thickness, and the internal stratigraphic architecture...

Here we applied structural geology methodologies with the aim of unraveling the Quaternary history of the active northern Matese fault. This structure bounds the northern slopes of the Matese massif (Bojano basin), i.e., one of the most seismically hazardous regions of Europe which is the epicentral area of some of the strongest Italian earthquakes...

La Calabria è una delle regioni della penisola italiana interessata storicamente da terremoti di forte intensità e da sequenze sismiche di bassa magnitudo, anche di lunga durata, che evidenziano una sua costante evoluzione tettonica e un'elevata pericolosità sismica. La Regione Calabria, ormai da anni, svolge attività diversificate che mirano ad un...

The central Italy Apennines were rocket in 2016 by the strongest earthquakes of the past 35 years. Two main shocks (Mw 6.2 and Mw 6.6) between the end of August and October caused the death of almost 300 people, and the destruction of 50 villages and small towns scattered along 40 km in the hanging wall of the N165° striking Mount Vettore fault sys...

An integrated investigation including geological, geomorphological, geophysical and structural survey, tephra analyses, ¹⁴C and ⁴⁰Ar/³⁹Ar dating, as well as paleoseismic trenching along the N-Matese fault system is presented. The study allowed the characterization of the tectonic mobility of this structure as well as the associated Bojano basin sed...

Here we present a multiproxy record (δ13C, δ18O, major and minor element composition, mineralogy, and low-resolution biogenic silica content) from a lacustrine succession in the Sulmona Basin, central Italy. Based on previous tephrochronological constraints and a new 40Ar/39Ar dating of a tephra matching the widespread X-6 tephra, the record spans...

We present the first integrated tephrochronological study (major and trace elemental glass composition, Sr and Nd isotope analyses, and 40Ar/39Ar dating) for the last one tenth (∼82 m) of the ∼900 m-thick Quaternary lacustrine succession of the Fucino Basin, the largest and probably only Central Apennine intermountain tectonic depression that hosts...

Introduzione. In questo lavoro si sono applicate le metodologie della geologia strutturale al fine di ricostruire le fasi evolutive di una struttura tettonica attiva e sismogenetica. Nello specifico è stata esaminata la faglia bordiera del bacino di Bojano ("Northern Matese Fault system" in Galli e Galadini, 2003. NMFS nel seguito) allo scopo di de...

Here we describe the macroseismic survey of the 24 August 2016 earthquake in central Italy (MW 6.2). By applying a revised version of the Mercalli-Cancani-Sieberg scale, we estimated the site intensity in more than 300 localities of Lazio, Abruzzi, Umbria and Marche regions, providing the Civil Protection with a quick and robust snapshot of the ear...

Here we present the first integrated tephrochronological study (major and trace elements glass composition, Sr and Nd isotope analyses and 40 Ar/ 39 Ar dating) for the uppermost ~82 m of the ~900 m-thick Quaternary lacustrine succession of the Fucino Basin. Located in a favorable position with respect to the prevailing westerlies, and in a good ran...

Much of our knowledge and understanding of the spatiotemporal variability and mechanisms underlying Quaternary climatic changes rely on regionally representative, high-sensitivity and chronologically well constrained proxy records. Quaternary lacustrine successions from Central Apennine tectonic basins in central Italy, have been shown to fulfill t...

A 82 m-long borehole was retrieved from the Fucino Basin, the largest intermountain tectonic depression of the Central Apennine. It hosts a ca. 900 m-thick and continuous succession of fine-grained lacustrine sediments, interbedded with several fall-out deposits from the pery-Tyrrhenian Quaternary volcanic centers, and potentially spanning back to...

New palaeoseismic trenching across the main splay of the Fucino fault system provides evidence for a High Middle Age surface-faulting episode conceivably associated with a disruptive earthquake, similar to the one that occurred in 1915 (Mw 7.0). The existence of this event, which has already been suggested by some previous studies, implies a shorte...

An 82m long sedimentary succession was retrieved from the Fucino Basin, the largest intermountain tectonic depression of the central Apennines. The basin hosts a succession of fine-grained lacustrine sediments (ca. 900 m-thick) possibly continuously spanning the last 2 Ma. A preliminary tephrostratigraphy study allows us to ascribe the drilled 82m...

The Calabrian Arc is the epicentral region of one third of the strongest earthquakes of Italy (M w ≥ 7.0). These are confined within a narrow peninsula which is the emerging portion of a slab-related accretionary wedge, and all occurred in the past four centuries. Therefore, here more than anywhere in Italy, historical seismicity alone is not suffi...

The selection of specific elastic response spectra according to soil categories is the standard to account for site effects in engineering design and general-purpose hazard maps. Most of the international seismic codes are based on the average shear wave velocity of the upper 30 m (Vs30) to discriminate between soil categories. The works of Borcher...

Hydrological variability over the Apennines during the Early Last Glacial precession minimum, as revealed by a stable isotope record from Sulmona basin, Central Italy ABSTRACT: A multi-proxy record was acquired from a Late Pleistocene lacustrine succession in the Sulmona basin, central Italy. Previous and new tephrostratigraphic analyses of six vol...

The Irpinia Fault (i.e., Mount Marzano Fault System: MMFS) was responsible for the devastating 1980 earthquake (Mw 6.9) that caused the longest surface faulting ever observed in Italy (> 30 km). Early paleoseismological studies have revealed a ~ 2 kyr recurrence time for 1980-like characteristic earthquakes on this fault system during the Holocene....

Integrated electron microprobe analyses (EMPAs) on glass and Sr–Nd isotope analyses have been performed on 17 tephras from the Middle Pleistocene Mercure lacustrine succession, southern Apennines. Two 40Ar/39Ar ages and the recognition of four relevant tephras from Colli Albani, Sabatini and possibly Roccamonfina volcanoes allowed us to ascribe the...

Here, we describe an original geophysical multi-method approach applied to the Mount Marzano Fault System. This is one of the most hazardous seismogenic faults of the Apennines (Irpinia, southern Italy), and it was responsible for the 1980, Mw 6.9, earthquake, along with many others before. We carried out electrical resistivity tomography (ERT), gr...

This work shows the result of an Electrical Resistivity Tomography survey carried out for imaging and characterizing the shallow subsurface affected by the coseismic effects of the Mw = 6.1 Emilia-Romagna (North Italy) earthquake occurred on 20 May 2012. The most characteristic coseismic effects were ground failure, lateral spreading and liquefacti...

The Magnola Mounts (the Abruzzi, central Italy) are bound towards the Fucino Plain by a steep fault slope that is marked at its base by a continuous rock fault scarp (a "nastro", in Italian). In the Apennines, this particular feature is often interpreted a priori as evidence of Holocene tectonic activity, although sometimes climate-related exhumati...

Morphological, stratigraphical and structural investigations integrated with palaeomagnetic and tephrostratigraphic studies and 40Ar/39Ar measurements allowed us to define the Quaternary tectonic–sedimentary evolution of the epicentral area of the L'Aquila 2009 earthquake (Mw 6.3). This area roughly matches the Paganica–San Demetrio–Castelnuovo (PS...

p>Most of the inhabitants of northern Italy were woken up during the night of May 20, 2012, by the Mw 6.1 earthquake [QRCMT 2012] that occurred in the eastern Po Plain. The mainshock was preceded a few hours before by a Mw 4.3 shock, and it was followed by a dozen Ml >4 aftershocks in May and June, amongst which 11 had Ml ≥4.5. On May 29, 2012, a s...

In 2009 the Government Commissioner and the Italian Civil Protection Department assigned the Institute of Environmental Geology and Geoengineering (IGAG) of the Italian National Research Council (CNR) to evaluate the geohazard level affecting the central archaeological area of Rome, including Palatine hill, Roman Forum and Coliseum. In the framewor...

We have carried out the macroseismic survey of both the May 20 (Mw 6.1) and May 29 (Mw 6.0) earthquakes in Emilia (Po Plain, northern Italy) by applying the Mercalli-Cancani-Sieberg scale, on 190 localities, mainly spread south of the Po River. Our data account for an Io 7 MCS evaluated for both earthquakes, with an Imax 7-8 assigned to the village...

An integrated subsoil model for seismic microzonation in the Central Archaeological Area of Rome is presented in this study. This model was created in the framework of a research project aimed at evaluating the geohazard level affecting Palatine hill, Roman Forum and Coliseum. A multidisciplinary survey was carried out mainly in 2010 including cont...

Urgent urban-planning problems related to the 2009 April, Mw 6.3, L’Aquila earthquake prompted immediate excavation of palaeoseismological trenches across the active faults bordering the Aterno river valley; namely, the Mt. Marine, Mt. Pettino and Paganica faults. Cross-cutting correlations amongst existing and new trenches that were strengthened b...

The M w 6.3, 2009 earthquake (L'Aquila, central Italy) was characterized by discontinuous surface rupture along the 19-km long NW-SE trending Paganica-San Demetrio fault system. The earthquake nucleated just below the town of L'Aquila at a depth of ca. 9 km, rupturing mainly toward SE. Due to the high urbanization of the area and to centuries-long...

La microzonazione è da intendere come strumento di supporto alla pianificazione del territorio e alle misure di prevenzione del territorio per interventi di emergenza, di recupero e ricostruzione. In tale ottica, la microzonazione si configura come strumento di riduzione del rischio sismico. L’osservazione dei danni provocati da un terremoto spesso...

In questa memoria sono descritti i metodi di indagine utilizzati per realizzare il modello di sottosuolo dell'area Archeologica Centrale di Roma, al fine di valutarne la pericolosità sismica locale. Lo studio è stato realizzato per conto del Commissario delegato per le Aree Archeologiche di Roma e Ostia Antica e in stretta collaborazione con il Dip...

The paper presents a methodology aimed at providing a geographic distribution of losses on the urban area so as to be helpful for developing or enhancing a seismic emergency plan. Basically, two main steps are required to achieve this purpose: a local seismic hazard analysis and a seismic vulnerability assessment. Data required for the seismic haza...

L’applicazione della macrosismica europea (Grünthal, 1998; in seguito EMS) può presentare, almeno per chi scrive, difficoltà collegate alla suddivisione degli edifici di un centro abitato secondo le classi di vulnerabilità proposte dalla scala stessa; infatti, anche in occasione del terremoto de L’Aquila, non è risultato agevole assegnare con sicur...

The Mount Marzano fault system (MMFS) is the surficial expression of the seismogenic sour-ce which was responsible for one of the most catastrophic European earthquake of the past century (1980 Irpinia, Mw 6.9, ca 3000 fatalities). At the end of the eighties this fault has been investigated at two sites by Pantosti et al. (1993) and D'Addezio et al...

The April 6, 2009 L'Aquila event (epicentral intensity Io=9 MCS, 308 casualties) has been characterized by a Mw=6.3 and by a coseismic rupture of about 18 km along the NW-SE trending Paganica-San Demetrio fault system. The earthquake enucleated just below the L'Aquila town at a depth of 9 km, rupturing then toward SE, as showed by instrumental and...

On 6 April 2009, at 01:32 GMT, an Mw 6.3 seismic event hit the central Apennines, severely damaging the town of L’Aquila and dozens of neighboring villages and resulting in approximately 300 casualties (Istituto Nazionale di Geofisica e Vulcanologia, http://www.ingv.it; MedNet, http://mednet.rm.ingv.it/procedure/ events/QRCMT/090406_013322/qrcmt.ht...
