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 raccolta dati e relativa elaborazione per la realizzazione di carte di microzonazione sismica di livello3; si tratta di veri e propri protocolli per delineare procedure operative per la caratterizzazione delle Microzone Omogenee in Prospettiva Sismica (MOPS), la delimitazione delle Zone di Attenzione e la valutazione della Risposta Sismica Locale all'interno delle MOPS. In tal senso, si vuole sottolineare una volta di più il decisivo ruolo svolto dagli studi di microzonazione sismica quale strumento di mitigazione del rischio sismico, non solo nelle fasi post-evento, ma soprattutto nell'ambito di una lungimirante strategia di prevenzione che privilegi l'adozione di corrette scelte in sede di pianificazione e progettazione.

Oggi nello studio di siti adibiti a discarica ed in particolar modo per quelli divenuti tali a seguito di azioni illecite, risulta di fondamentale importanza la comprensione preliminare dell'estensione e della morfologia dell'area interessata dall'accumulo di rifiuti così come delle interrelazioni tra gli stessi ed il territorio circostante ed, in particolare, nel rilascio di percolato e biogas. I metodi di seguito proposti, pur seguendo due approcci distinti, hanno il fine comune di consentire la necessaria consapevolezza per pianificare e gestire al meglio ogni successiva azione di indagine e caratterizzazione puntuale che altrimenti si rivelerebbe sicuramente dispendiosa e non sempre efficace. Questo articolo riporta due casi studio condotti dai partecipanti del gruppo di lavoro con l'intento di mostrare il vasto campo di applicazione delle metodologie geofisiche nel rilevamento e nell'indagine delle principali caratteristiche di una discarica di rifiuti solidi. La presenza di discariche, in cui al corpo rifiuti spesso si associano biogas e percolato, determinano importanti variazioni di alcuni parametri fisico-chimici, individuabili mediante l'utilizzo di tecniche non invasive di tipo geofisico. Lo scopo del presente lavoro è l'analisi delle potenzialità e dei limiti dell'integrazione di differenti metodi geofisici (tomografia elettrica di resistività, polarizzazione indotta, metodo magnetico e georadar) per la localizzazione di rifiuti interrati di diversa natura. Nel primo caso di studio elementi chiave di novità di questo approccio per la caratterizzazione e il monitoraggio dell'area di discarica sono la combinazione e l'integrazione di diversi approcci metodologici (geofisici e non), come l'uso parallelo e combinato di dati raccolti da satellite, aereo e in situ, che sono stati convalidati attraverso indagini geofisiche (metodi geoelettrici) e che hanno rivelato l'efficacia di questa strategia. La seconda parte di questo lavoro ha avuto lo scopo di verificare l'efficienza di antenne GPR (Ground Penetration Radar) a diversa frequenza (100 MHz - 270 MHz) e indagini magnetometriche gradiometriche in terreni di natura piroclastica dove sono stati interrati oggetti di varia natura e a diverse profondità. L'attività ha permesso di conseguire importanti informazioni sulla scelta della frequenza di utilizzo delle antenne GPR e tecniche magnetometriche in terreni piroclastici e sulla risposta che tale tecnica fornisce nell'identificazione di oggetti sepolti come fusti metallici e muretti in tufo.

This paper presents an overview of the geophysical activities for the seismic microzonation of 138 municipalities belonging to four Italian regions (Abruzzo, Lazio, Marche and Umbria) that were severely damaged by the seismic sequence of Central Italy (August 2016-January 2017). This study is the result of a collaborative effort between research Institutions and professional geologists with the support of local Administrations and the Italian Civil Protection Department and sets an unprecedented large-scale example of geophysical investigations supporting detailed seismic microzonation studies. This manuscript presents the methodological approach adopted for the geophysical activities, including the technical protocols and procedures, the best practices, the final products and the results supporting a detailed microzonation study of III level. The first step of the study was the collection and critical review of all available geophysical and geological information for planning the new geophysical surveys (specifically their type and location), in order to assess the subsoil geometry and the seismic characterization of the areas under investigation. Integration with the newly acquired geophysical data allowed the identification of zones with homogeneous local seismic hazard as well as the reference seismo-stratigraphy for each area, defining for each geological unit the ranges of the relevant properties in seismic amplification studies: layering and thicknesses, density, P-wave and S-wave seismic velocity. We also present a few representative case studies illustrating the geophysical investigation for different geomorphological situations. These examples, together with the findings of the entire project, are discussed to point out the strength points and the criticalities, as well as the necessary requirements in the application of geophysical methods to detailed microzonation studies.

Le metodologie e gli strumenti per la ricerca indiretta di siti contaminati hanno avuto negli ultimi anni un sostanziale sviluppo. In particolare, lo sviluppo di metodologie geofisiche, utilizzati in altri campi, permettono diraggiungere risultati molto importanti nella ricerca di discariche abusive sepolte. In questo lavoro, si descrivono tali approcci per rilevare e studiare le principali caratteristiche di siti contaminati ed in particolare da discarica occulte di rifiuti solidi. Attraverso l'integrazione di metodi geologici, geografici e geofisici, viene effettuata un'analisi multi-temporale dell'evoluzione morfologica delle aree di indagine utilizzando foto aeree e satellitari disponibili e riferite alle aree di studio. Successivamente, mediante la combinazione di indagini geofisiche da superficie del tipo geoelettrico, geomagnetico ed elettromagnetico, si arriva ad un modello geologico-geofisico del sottosuolo che ci permette di fare ipotesi più accurate. Un esempio di tale approccio è stato testato con successo per assistere la Procura di Salerno durante un'indagine specifica su una discarica illegale. Tutti i dati raccolti sul campo sono stati utilizzati sia per la ricostruzione multi-temporale della storia del sito, che per definire la geometria attuale della cava e la geologia del sito. Gli elementi chiave della novità di questo metodo sono la combinazione e l'integrazione di diversi approcci metodologici, come l'uso parallelo e combinato di dati satellitari, aerei e in situ, che sono stati validati in una vera indagine e che hanno dimostrato l'efficacia di questa strategia.

International audience; Study of the tectonically active L'Aquila Basin offers new insights into both the creation of the extensional intermontane basins of the central Apennines of Italy and their tectono-sedimentary evolution through time. The combination of large mammal remains, ostracods, molluscs, Mousterian tools, and 14 C dating allows better definition of the onset and stratigraphic evolution of the L'Aquila Basin. Interpretation of a seismic reflection profile and well-log data allow evaluation of the subsurface setting of this sedimentary basin and its tectono-sedimentary evolution. The occurrence of a wedge-shaped seismic unit at the base of the basin sedimentary succession defines the first phase of basin fill during a late Piacenzian–Gelasian synrift stage. Activity along the main fault of the extensional fault system responsible for the onset and subsequent development of the western sector of the L'Aquila Basin (L'Aquila– Scoppito subbasin) migrated from southwest to northeast, reaching the presently active Mount Pettino normal fault only in the late Pleistocene–Holocene. The onset of sedimentation in the L'Aquila Basin was synchronous with the onset in the Tiberino Basin, and so the idea that these extensional GSA Bulletin; Month/Month 2017; v. 129; no. intermontane basins become progressively younger from the Tyrrhenian toward the Adriatic side of the central Apennines is rejected. In the northern and central Apen-nines, only two major syndepositional ex-tensional domains can be recognized: a late Miocene rifting area, which includes all the late Miocene extensional basins in Tuscany, and a late Pliocene to earliest Pleistocene rifting area, which possibly includes all the intermontane basins from the Tiberino Basin to the Sulmona Basin. The different time gaps between compressional and exten-sional deformation at any given locality in the central Apennines could indicate a partial decoupling of processes responsible for the migration of shortening and extension toward the foreland. Diachroneity between the eastward migration of shortening in the foreland and extension in the inner part of the orogen supports the notion that the central Apennines were created as a result of a partially decoupled collision zone. Study of the onset of the central Apennine extensional intermontane basins, together with their seismic activity, indicates that the central Apennine postorogenic extensional domain represents an archive of ~3 m.y. of continued crustal extension. These findings help to refine models of the long-term extensional rate of the central Apennines, and they provide a basis for more reliable seismotectonic models for one of the most seismically active sectors of the central Mediterranean area.

The Volturno coastal Plain (VP), laying from Mondragone town and Lago Patria (Southern Italy), was intensely modified by antrophic activities mainly in the last centuries; crops and urban zones took the place of natural lands. The urban sprawl as the events associated to the global warming and local climate deteriorations (relative sea level rise, storm surges, river flood) are the main causes of coastal erosion. During the last 3-4 ka, VP has experienced an increase in sedimentary input, a substantial slowdown of sea level rise rhythms and a progressive seaward shift of coastline and barrier-dunes-lagoon systems. In particular, the delta system development and the strongest coastal progradation phase (about 2 km) started from Roman period (ca. 2.5 ka B.P.) and reached the apex between c.a.1500-1800 A.D. coinciding with the period called Little Ice Age. From historical maps, aerial photographs, topographic maps and satellite images covering the 1817-2012 time span, 10 shorelines were delineated. Along 165 transects spaced 200 m apart, the shoreline variations and the trends were assessed; the first was calculated for each pair of two consecutive shorelines, while the latter by using all the shorelines available for the 1957-1997 and 1997-2012 time windows. In the first time window, both sides of Volturno river mouth and the Ischitella locality were in erosion. At the beginning '60s, the Volturno coastal zone was deeply modified by the antrophic pressure, 4 rivers cross-sections and 10 dams were built in the Volturno basin. Moreover, since the '70s, the urban environment expanded rapidly and the construction of seaside tourist center Pinetamare took place. In order to preserve the beaches and the houses very close to the shoreline, several coastal defences were also built from 1978 to 1979 nevertheless they stabilized the Pinetamare zone but increased the erosion in Ischitella locality. In the 1997-2012 period, moving from Lago Patria toward Mondragone city, a first coastal sector was in erosion (-1.4 m/year), the area of Pineta Mare was characterized by stability (0.6 m/y), northward an accretion rate of 2m/year was recorded. At Volturno river, the left side was in erosion (mean value = -2 m/y) while the right side in accretion (mean value = 1.4 m/y). Still moving northward, there are other two sectors, the first was characterized by a rate of -2m/year and the last by a rate of 1m/year. At present, the coastal defences do not work well, they are for the greatest part under seawater; this condition favor the establishment of sectors in erosion alternate with those in accretion. The knowledge of both historical evolution and of present day shoreline trend at VP can be considered a vital tool to support the development of a coastal system able to adapt and cope with natural hazard and to improve its naturalness.

The Sibari Plain is located close to the boundary between the Calabrian Arc and the Southern Apennines. During the Holocene, the plain was characterized by the Crati delta building and by the re-activation of the transverse Sybaris Fault Zone (SFZ), a northward dip fault interpreted as an oblique normal-dextral fault zone, 45°N-55°N striking, recognized by archaeoseismic data recorded in the Sybaris ruins. We carried out a muldisciplinary approach combining boreholes stratigraphy and ancient cartography analysis and acquisition of 2D Electrical Resistivity Tomography (ERT). We identified four main units: (1) the Late Pleistocene sandygravelly alluvial and coastal plain deposits, (2) early-middle Holocene clayey sediments of marine-marshy-lagoon origin, (3) a middle-late Holocene sandy beach ridge system and (4) late Holocene deltaic sediments. The elevation contours of the top for the Pleistocene basement reveal a Holocene SFZ activity or reactivation that has probably created space for a different arrangement of late Pleistocene and Holocene units in the surrounding Crati River area. Furthermore, an ERT allows to observe evidences of the SFZ close to Sybaris. Considering the different stratigraphic units thickness and association, we suggest that the SFZ Holocene activity drove the plain evolution influencing the development of different depositional environmental conditions between hanging wall and footwall. In detail, major delta-building events reconstruction suggests that at the end of last-glacial transgression (around 6 kyr B.P.) a wide wetland and a shallow water bay environment took place on the hanging wall. On the foot wall, the Crati River built its terminal plain and its delta. Up to Sybaris time (2.7-2.5 kyr B.P.), the high subsidence on the hanging wall favoured the deposition of thick wetland deposits passing seaward to the shallow water sediment of the coastal embayment. At the same time, on the foot wall the Crati Delta progradation went on reaching the area southward from the Sybaris settlement. Up to the present day, the tectonics has been influenced the plain topography, producing a depressed area on the hanging wall, marked by widespread presence of humid zones. The present confluence between Crati and Coscile Rivers happens in correspondence to the SFZ. We suggest that the the ground-tilting drives the Coscile River channel to avulse periodically toward the SFZ (the down-tilt side with minimum elevation), with the consequent confluence in the Crati River, during the active tectonic period and to move away from the SFZ during quiescent one producing the two rivers separation. The latter can be favored by sediments accumulation close to the SFZ, which re-establish the pre-tilting equilibrium. In conclusion, our approach aims to identify the SFZ as a major agent controlling deposition and landform development by creating accommodation space for the deposition of coastal sediments along Sibari Plain during the Holocene.

A crucial task in earthquake hazard assessment is the problem of investigating buried main faults and secondary features to evaluate their seismic hazard potential, because they cannot be easily detected by surface geological analyses. The Lamezia Terme territory, located in the westernmost edge of the Neogene-Quaternary "Catanzaro Trough", is influenced by the presence of different major trascurrent/oblique faults which belong to the Lamezia Terme-Catanzaro Fault (LCF), a NW-SE trending seismogenetic trascurrent fault zone. The subsurface geometry of LCF is recognizable on a morphological basis and constrained by commercial profiles (VIDEPI Project); however, quality of commercial reflection profiles is often inappropriate to face the extreme structural complexity related to this seismogenetic zone. Although these geophysical surveys have provided insight into the largescale geology, resolvable with high-energy and low-frequency seismic acquisition systems, only high-frequency seismic studies at specific sites can resolve the fine-scale features required to interpret Quaternary processes. In Lamezia Terme area, in fact, the outcropping heterogeneous Quaternary terrigenous successions probably absorbed the rupture's stress related to historical fault activity; this do not permit to delineate active faults with the traditional geological mapping and/or paleoseismic investigation. High Resolution (HR) seismic reflection method, integrated with a pure surface geology approach, can overcame the problem of absence of clear geomorphological/stratigraphic indicators of synsedimentary fault activity, permitting a detailed structural imaging at shallow depth, which is crucial to document recent activity and assess seismogenic potential of blind faults. In Lamezia Terme area, since no detailed information on the faults segment which cross this zone is available, was identified a sector, 600 m-wide (but the extension of the zone is uncertain), subject to environmentally protective restrictions due to the presence of LCF. Therefore, in order to improve the imaging of shallower more recent sequences, we acquired, at "Terme Caronte", near the village of Sambiase, four HR seismic reflection/refraction profiles (total length about 1500 m). Seismic data were collected by a Swept Impact Seismic Source (VibSist-500), appropriate for shallow reflection surveys, and an array of receivers consisting of 96, 4.5 Hz, vertical geophones. Setting the receiver spacing to 5 m and the source interval to 10 m, we recorded dense data within a wide offset range. This study aims to develop an improved seismic stratigraphic framework for Lamezia Terme area in order to recognize seismic units distribution and the possible presence of buried fault segments linked with the principal displacement zone, which are fundamental information for a quantitative approach to seismic hazard assessment and the subsequent land-use planning.

In the framework of PON AMICUS, the Institute for Coastal Marine Environment (IAMC-CNR) of Naples, in partnership with University of Calabria (DiBEST Department), carried out at "Terme Caronte", in the Lamezia Terme territory, a geophysical survey. The main goal of the survey was the shallow (i.e. first 150 m) seismic imaging of the subsurface of this area. Four High Resolution (HR) seismic reflection/refraction profiles (total length about 1500 m) were acquired using an array of receivers consisting of 96/72 channels with a Swept Impact Seismic Source (VibSist-500). Seismic studies were integrated with MASW and MAM analysis and n.8 Horizontal to Vertical Spectra Ratio (HVSR) investigation. The performance of an active and passive seismic study was planned to study two main targets: A) The internal geometry of fan deposits (which characterize Caronte aquifer) and their stratigraphic relationships with the Pliocene clays, the crystalline basement and with the aquifer system of Eufemia-Lamezia plain. B) The shallower, more recent sequences, to detect possible buried faults linked to master Lamezia Fault (LF), a NW-SE trending seismogenetic trascurrent fault, and the subsequent land-use planning along this active and capable fault zone. This study aims to develop an improved seismic stratigraphic framework for this area in order to better understand intrinsic processes of fan construction and its tectono-sedimentary evolution linked to LF. The analyzed seismic sequences will be calibrated with borehole data, to recognize seismic units distribution and the possible presence, in the hangingwall of LF, of buried fault segments linked with the principal displacement zone.

This paper shows an example of 3D high-resolution seismic tomography that implements an acquisition geometry, which provides for the housing of sensors in the sub-vertical discontinuities of a tuff cliff. The site test was located in the Sorrento Peninsula, a major Quaternary morphostructural unit of the western flank of Southern Apennines, consisting of a narrow and elevated mountain, that separates two major embayment of the eastern Tyrrhenian margin. The overall geological setting is characterized by a carbonate bedrock, covered by pyroclastic deposits (i.e. "Campania Ignimbrite"), originated from the Campi Flegrei volcanic district. The occurrence of steep slopes and the high relief area, along with the marine erosion at the base of the coastal cliff, creates favorable conditions for the occurrence of a generalized instability of the slopes characterized by tuff rock falls as prevailing landslide phenomena. An accurate prediction of these mass movements is difficult if not accompanied by an intensive hydrogeological and geotechnical monitoring and hazard assessment; the instability phenomena, in fact, can be caused by the presence of pervasive fracturing and cavities in the tuff rock. Due to logistical reasons, it is not possible to perform seismic surveys using typical acquisition setup, therefore we utilized a particular experimental procedure, characterized by an acquisition geometry which included the installation of the sensors on the tuff cliff and energize along concentric semicircles to obtain the maximum of the seismic resolution. A non linear seismic inversion was used to obtain 3D High-resolution seismic tomography in terms of P-wave velocity and S-wave velocity. The interpretation of the experimental results in terms of 3D Vp/Vs ratio showed anomaly zones in the investigated rock. We identified an area with a low Vp/Vs value that we ascribed to a medium porosity or in dry condition with respect to the surrounding rock mass.

A modified version of the GEOWAVE (Watts, 2009) model is used, taking properly into account the decreasing nearshore tsunami wavelength through a system of nested grids. GEOWAVE simulates tsunami waves generation, propagation, and inundation using a fourth order fully nonlinear equations, fully dispersive Boussinesq wave model with multiple wave dissipation mechanisms, wave breaking, and dry land overflow. In the numerical simulation, the Tsunami Open and Progressive Initial Conditions System (TOPICS) is adopted to produce 3D tsunami source for tsunamis generated by submarine slides and slumps, while a 25 m uniform spacing grid is derived from the bathymetric dataset of the Naples Bay. Interesting results of tsunami simulation, in the above-mentioned areas, show that the amplitude of wave run-up ranges from 0.90 m near to Procida Island and up to 1.90m nearness of Naples Port. This difference in run-up is ascribed to a different coastal morphology. In fact, the port of Naples offshore has a slope of 3-4 degrees while the Procida Island offshore of 25-30 degrees.

Beach environments have a relevant value related to their ecological and economic (e.g. touristic) features. Many of the world's major cities are located in coastal areas; therefore, the increasing of the erosional phenomena due to anthropogenic impact makes necessary to track shallow geology and to collect data on land-marine transition zone. During the coastal management planning, one of the main problem is represented by the lack of information about backshore and foreshore zones. Obtaining a continuous profile of the subsurface in the land-sea transition zone is a challenging task: the low depth prevents the investigation by conventional research vessels and the presence of unconsolidated sediments can cause attenuation of the seismic signal. Moreover, in transition areas low signal-to-noise ratio due to poor coupling of the receivers with the sea bottom and strong ambient noise due to wind, surf and currents can affect the data quality. During "SIGIEC" PON Project (http://www.sigiec.sister.it), we adopted a Land-Sea (LS) seismic configuration. The method was tested in the Bagnara Calabra site (Calabria, southern Italy), where 10 LS high-resolution seismic refraction profiles were acquired. The site represent an example of pocket beach, with high and rocky coasts and where long shore currents are very weak.

This brief report discusses a key aspect of seismic risk, i.e., the underestimation of site amplification effects in many Italian urbanized areas that are located in alluvial plains or valleys and the related problem of computing the seismic hazard of a site from an accurate and thorough knowledge of local geologic and geoseismic factors.

The coastland surrounding the mouth of Volturno river is a vulnerable environment to both natural disturbances and strong anthropogenic pressure. Particularly, the combined effect of sea level rise and coastal erosion has the potential to enhance the ingression of sea water within the aquifer. Hence, monitoring the sea water intrusion and the vegetation-related responses represents a priority for the sustainable development of the coastal areas. A sampling transect was planned from the coast close to the mouth of the river to the inner part of Castel Volturno municipality. Main aim was to investigate spatial variations of groundwater salinity and physiological responses of the vegetation. For this purpose, well-exposed leaves and small portions of woody twigs of Rubus ulmifolius and Ulmus minor growing along this transect and soil and water table samples were collected for stable isotope analyses. Leaf tissues were used to determine carbon isotope discrimination (?) of photosynthetic products with different turnover rates, such as leaf dry matter and leaf soluble fraction. Xylem and soil water was quantitatively extracted by means of a cryogenic vacuum line to determine oxygen isotope composition (?18O). ? of leaf tissues indicates interspecific and spatial variations in water-use efficiency (WUE), stomatal conductance and photosynthetic performances. An increasing trend of ? was observed for U. minor from the coast to the inner region of Castel Volturno area. The ?18O values of xylem water indicate that U. minor uses a deeper water source than R. ulmifolius. Moreover, the absence of a significant trend in ?18O of xylem water along the transect suggests a rather homogeneous water source for the plants.

L'Unità di Geofisica dell'Istituto per l'Ambiente Marino Costiero del CNR, sede di Napoli, in seguito alla collaborazione con l'Istituto di Geologia Ambientale e Geoingegneria (IGAG) avente per oggetto la Microzonazione Sismica dei Fori Imperiali e del Colle Palatino in Roma, ha effettuato un serie di indagini sismiche sia in foro (Down-Hole e Cross-Hole) che in superficie (MASW e Tomografia sismica a rifrazione) con l'obiettivo di caratterizzare dal punto di vista dinamico i litotipi rappresentativi dell'area archeologica in esame. A partire dal mese di settembre del 2010 e fino alla fine del mese di gennaio del 2011, l'Unità di Geofisica ha acquisito e contemporaneamente elaborato i dati di campagna fornendo i risultati ottenuti al coordinatore di progetto.

Il gruppo di geofisica dell'Istituto per l'Ambiente Marino Costiero del CNR, coordinato dal dott. Vincenzo Di Fiore, ha eseguito nello specchio d'acqua del "Porticciolo della Tonnara" antistante alla sede CNR-IAMC di Capo Granitola (TP) un test di sismica marina multicanale. Il team ha eseguito nei giorni 10 e 11 ottobre 2012 le operazioni di acquisizione di 4 profili sismici, di cui tre seriati, al fine di ottenere dati di tomografie sismiche a rifrazione elaborati mediante tecniche 2D e 3D. L'indagine geofisica, che ha interessato la fascia batimetrica compresa tra -2m e -5m, ha previsto il posizionamento del cavo geofonico d'acquisizione (bay-cable) direttamente sul fondale del porticciolo allo scopo di valutare sia i limiti che le potenzialità del metodo, ma anche per definire i parametri di comportamento e i caratteri strutturali dei depositi marini recenti e di età quaternaria presenti nell'area. La sperimentazione di tale tecnica, oltre a consentire l'acquisizione dei dati anche in termini di primi arrivi e di onde superficiali, ha permesso di elaborare modelli di velocità bidimensionale delle onde P ed S. Attraverso l' analisi del campo di variabilità , sono state dedotte utili informazioni sulla struttura del fondo mare sia in termini di geometrie che di caratteristiche elastiche del mezzo indagato.
