    Notes: Summary The effect of infection with a retrovirus carryingv-raf/v-myc oncogenes (J2 virus) on the in vitro proliferation of human large granular lymphocytes (LGL) was investigated. LGL infected with J2 virus (J2LGL), unlike uninfected cells, grew with a proliferation peak eight days after infection. Such cells retained the morphology and functional properties typical of LGL. Furthermore, 5% of J2LGL produced virus the day after infection, whereas non-virus production was detectable five days later. These data indicate that J2 virus provides a transient mitogenic signal for LGL.

    An overview of earthquake related liquefaction events in Italy (2011)
    Details
    Publication Date: 2020-11-30
    Description: This report was prepared by Mr Edoardo Borgomeo during the summer pause of Imperial College (London, UK) lectures. Mr Borgomeo have joined the Istituto Nazionale di Geofisica e Vulcanologia (Italian Institute of Geophysics and Volcanology) for an internship under the supervision of Dr. Giuseppe Di Capua and Prof Silvia Peppoloni. This internship was an opportunity to gain an understanding on the functioning of a research institute and on the tasks a researcher has to undertake in the creation of a scientific publication. The result of the internship is presented in the following report that investigated the phenomenon of liquefaction under seismic conditions. The most serious direct effect of earthquakes on buildings and structures is ground shaking. However earthquake shocks might pose other hazards in the form of soil liquefaction, which can result in considerable financial losses. Some soils such as quicksands and quickclays can give rise to major problems when disturbed by ground shaking. The ground vibrations produced by an earthquake lead to a decrease in the effective stress and in the shear strength of the soil which in turn trigger the liquefaction.

    Revised seismic classification of the ITACA stations, according to the EC8 and the Italian norms site classes (2011)
    Details
    Publication Date: 2020-10-26
    Description: The activities carried out within Task 2 aim to collect, organize and synthesize geological, geomorphological, geotechnical and geophysical data for the location site of the Accelerometric National Network (RAN) stations in Italy, managed by the Department of Civil Protection, to improve the knowledge about the subsoil (see Delverable D05) and to permit a subsoil and topographic site classification based on EC8 categories. At the end of the project the subsoil of 695 stations have been classified using an hybrid approch, based on surface geology, spectral classification and Vs profils from different recording tecniques (DH, CH, MASW, ESAC). These activities have been useful to link the ITACA database with the software REXEL to select natural accelerograms, compatible with Norme Tecniche per le Costruzioni (NTC2008) and EUROCODE 8 (EC8) spectra, which may also reflect characteristics of the source in terms of magnitude and epicentral distance. For 688 station sites have been provided also a topographic classification using a GIS based semiautomatic method with “by-hand” corrections using topographic maps and/or Google Earth software. A Microsoft Excel Database which also allows to track all changes that have been made since the beginning of the project related to the site classification has been developed.

    The Aterno valley strong-motion array: seismiccharacterization and determination of subsoil model (2012)
    Springer Science
    Details
    Publication Date: 2020-10-26
    Description: The paper focuses on the strong motion array deployed in the upper Aterno River Valley, in the immediate outskirts north-west of the town of L’Aquila, which is part of the Italian Strong Motion Network operated by the Department of Civil Protection. The array is composed of six accelerometric stations located along a cross section of the valley. The importance of this array relies on the fact that a large amount of high-quality records were obtained during the 2009 L’Aquila seismic sequence, from both the mainshock and several aftershocks. These data are especially important to investigate site effects in sediment-filled valleys during moderate earthquakes in epicentral area because well-documented observational studies are very limited in the literature. However, the main drawback for the study of site effects in the Aterno valley is the lack of a detailed knowledge of the geometry of the valley, soil layering and dynamic properties of materials. The main motivation for this study stems from the need to provide a reliable subsoil model of the valley coupled with high-quality strong motion data. Based on the above, in the framework of S4 project, a major effort was undertaken to get a trustworthy cross section of the valley by an ad hoc investigation, comprising geological and geotechnical surveys as well as an extensive geophysical campaign, characterized by both active and passive measurements. These results were complemented by additional geological and geotechnical data available in the literature. By merging all the information acquired, a 2D subsoil model of the transversal section of the upper Aterno valley has been produced. The valley is characterised by an asymmetric shape with a shallower rock basement at the western edge of the valley that deepens at the valley centre. Moreover, based on the results of geophysical tests, representative Vs values were assigned to the different lithologic units forming the alluvial deposits filling the valley. Shear wave velocity is a fundamental parameter for ground response studies and it is also effective in classifying the accelerometric station from a seismic point of view. The 2D model may be therefore, considered a benchmark model for future studies of site effects. It will offer the possibility to examine site effects with a complex underlying geology and to validate the results of numerical simulations of site response analyses with the numerous observations from earthquake recordings, both for weak and strong ground motion conditions.

    Applicazioni di livello “0” della metodologia utilizzata per la valutazione del rischio sismico di Sistemi Urbani, utilizzando l’analogia delle reti neuronali (2010)
    Details
    Publication Date: 2021-06-09
    Description: Questa ricerca, condotta nell’ambito del Progetto RELUIS – Linea 10, ha riguardato la messa a punto di un modello di rischio sismico per Sistemi Urbani con approccio multilivello, utilizzando l’analogia con le reti neuronali. Il primo passo è stata l’elaborazione del livello 0, basato su banche-dati, disponibili a livello nazionale, relative alla pericolosità sismica di base e locale (INGV) e a dati di censimento dei comuni italiani (ANCITEL 2001; ISTAT 2001) per la descrizione fisica e funzionale dei centri abitati/sistemi urbani analizzati. Per semplicità e per omogeneità tra i molti dati elaborati sono stati trascurati due aspetti rilevanti per il modello di rete neuronale, che intervengono invece ai livelli successivi, ovvero l’aspetto della “soglia” di perdita di capacità di una componente di sottosistema (sia per evoluzione che per connessione) e l’aspetto della “capacità iniziale” di una componente di sottosistema prima dell’evento sismico. La valutazione della perdita di capacità complessiva di un Sistema Urbano a livello 0 è stata quindi calcolata come l’insieme delle perdite di tutti i sistemi combinati tra loro (con opportuni pesi) e quindi con un valore complessivo.

    Definition of the standard format to prepare descriptive monographs of ITACA stations (2010)
    Details
    Publication Date: 2020-10-26
    Description: In the previous S6 Project (2004-2007 DPC-INGV Framework Program) a monograph was carried out, that was drawn up for many stations, that were part of the former ENEL accelerometric network. In these monographs all the ENEL documentation about geological information as well as geognostic and geophysical data was included. Knowledge of geological and geomorphological context, and the mechanical and dynamic characteristics of the stations subsoil is fundamental for studies on the attenuation laws and the selection of accelerograms to be used as a seismic input for dynamic analyses for which a classification of the stations subsoil according to the EC8 and national code provisions is necessary. Considering the huge number of sites (over 600), this knowledge have to be rationalized and homogenized so as to arrive at a common and comparable level of information. The station monograph carried out within the past S6 INGV Project had tried to fill the gap in the knowledge of the recording station characteristics, with the advantage of providing a first screening on the quantity and quality of available data; however the collected data included in the monograph turned out to be uneven and incomplete since a robust standard for the collection, homogenization, representation and synthesis of data was not provided. Moreover, expert judgment for assessing quality of data, especially those derived from geotechnical and geophysical tests, was not taken into consideration. This problem has been addressed by Task 2, which has produced a new standard monograph for the ITACA stations. The new release of the station monograph is the first product of the 5 S4 Project (deliverable D3) and can be downloaded from the project website (http://esse4.mi.ingv.it). The new ITACA monograph provides a minimum level of information, homogeneous for all station sites, including multi-disciplinary data to satisfy the needs of different users and duly considers information previously not included. In detail, the new ITACA monograph consists in the following 12 cognitive modules, and various sub-modules.

    Ground motion recordings from the MW 6.3 2009 L’Aquila earthquake in Italy and their engineering implications (2012)
    Details
    Publication Date: 2020-10-26
    Description: The 2009 L’Aquila earthquake sequence includes the April 6 Mw 6.3 main shock and triggered events on April 7 and 9, each recorded on a digital network having five stations on the hanging wall of the main shock fault. We describe a geometric source model drawing upon inversions by others. We describe record-specific ground motion data processing that includes the incorporation of static displacements of up to 13 cm (downdrop of hanging wall). The resulting database includes 47, 38, and 31 corrected triaxial recordings from the April 6, 7, and 9 events, respectively. We present site conditions for recording stations, including recent surface wave and borehole geophysics. We demonstrate that the high-frequency data are weaker than expected for normal fault earthquakes of these magnitudes and that the data attenuate with distance at rates generally consistent with modified next generation attenuation (NGA) equations for Italy that were available prior to the event.

    Caratteristiche geologiche e classificazione di sito delle stazioni accelerometriche della RAN ubicate a L'Aquila (2010)
    Details
    Publication Date: 2020-10-26
    Description: L’evento sismico del 6 aprile 2009 è stato registrato da 57 stazioni accelerometriche delle RAN (Rete Accelerometrica Nazionale, gestita dal Dipartimento della Protezione Civile), alcune delle quali ubicate nella città di L’Aquila (stazione AQK) o nella porzione della Valle dell’Aterno a NW della città (AQA, AQF, AQG, AQM, AQP, AQV). Uno degli obiettivi del Progetto S4, finanziato nell’ambito della Convenzione 2007‐ 2009 tra l’Istituto Nazionale di Geofisica e il Dipartimento della Protezione Civile, consiste nella classificazione dei siti di ubicazione delle postazioni accelerometriche utilizzando le categorie di sottosuolo previste nell’EC8‐NTC2008. Nell’ambito del Task 2 è stata rilasciata una versione preliminare di tale classificazione (vers. 1.0), ottenuta soltanto su base litologica, utilizzando una mappa prodotta dall’INGV in un precedente progetto sismologico (Progetto S6 della Convenzione DPC‐INGV 2005‐ 2007). Questa mappa litologica deriva dalla Carta Geologica d’Italia in scala 1:100.000, mediante l’accorpamento in classi delle Formazioni Geologiche secondo un criterio litologico e di età del deposito. Alle varie classi litologiche ottenute è stata quindi attribuita una delle cinque categorie di sottosuolo (A, B, C, D, E) dell’EC8‐ NTC2008. Per le stazioni per le quali sono disponibili i profili di velocità delle onde di taglio VS, la categoria di sottosuolo è stata eventualmente corretta, scegliendo la classificazione ottenuta dal profilo di velocità delle onde di taglio nei primi 30 metri. Nei giorni successivi all’evento del 6 aprile 2009, i ricercatori dell’UR2 e dell’UR6 del Progetto S4, impegnati nel Task 2, hanno effettuato sopralluoghi finalizzati alla verifica della localizzazione geografica, delle condizioni morfologiche e geologiche locali di alcune stazioni di registrazione ubicate nell’area aquilana. Sulla base delle informazioni raccolte e dei dati acquisiti, è stata prodotta una versione aggiornata (vers. 1.1) della classificazione di sito per le suddette stazioni, attualmente disponibile sul sito web del Progetto S4 (http://esse4.mi.ingv.it).
