    Beschreibung: This work was carried out within the 2015 ART-IT project (Early Earthquake Alert in ITaly). Its main purpose is to investigate the performance and the critical issues of an early warning system with particular reference to the PRESTo system (PRobabilistic and Evolutionary early warning SysTem, [Iannacone et al., 2010; Satriano et al., 2011]) whose use has been tested in the framework of the above mentioned project. The correct operation of an early warning system can effectively guarantee a more effective management of a seismic emergency from the first seconds after the occurrence of a strong earthquake, allowing quick actions to reduce exposure and seismic risk. The work was substantially subdivided into two main steps. A first calibration phase, carried out in the first part of the project and aimed to identify the best values of the software configuration parameters in terms of event triggering and declaration. Once the values of the aforementioned parameters have been identified, the second phase of the work was focused on testing the software in real time configuration, on a test site area and the subsequent evaluation of its performance in terms of declaration and localization capacity. This work focuses mainly on the second part of the experimentation and is aimed describing and summarizing the analysis carried out to evaluate the response of the PRESTo software (and in general of an early warning system) after one year of experimentation and acquisition and highlight any problems and critical issues of the software and more generally of the rapid alert systems.

    Beschreibung: This simple and qualitative discussion is an attempt to include in a comprehensive framework the problem of earthquake forecasting and univocally clarify the meaning of "precursor" and the true importance of their study. It is also the starting point to present the potential of the electromagnetic precursor in the framework of classic precursors. The fact that seismic precursors are truly existing phenomena does not represent the solution to the problem of deterministic forecasting. Currently a precursor is not a prediction aid but an investigative tool of the earthquake preparation process: aka the complex mechanism of microfracturing, growth and self-organization of fractures that is necessary to produce ruptures in the crust. Scholz's "Theory of Dilatance" (ToD), improved and further developed for decades after 1960, remains one of the best explanations for the existence of observable precursors and still seems to highlight the only plausible common cause. ToD is presented here in an "extended" vision in the framework of geotechnical knowledge on rock fracturing in the laboratory. Dilatance is a systematic and necessary process with respect to rock breaking. It would itself be the ideal precursor to the earthquake if it did not lack the essential characteristic of being directly observable. At the moment, the only way to detect dilatance in nature is through its interaction with the surrounding environment and its ability to change the physical characteristics of the rock, that is, through secondary phenomena that it can cause. These phenomena sometimes visible on the surface are what we call precursors. We have reviewed the main "classic" precursors by examining them in the light of the ToD. The study of dilatance, which requires a comparative, systematic and extensive monitoring of precursor phenomena, could lead to a key of interpretation of the precursors themselves for the prediction of the earthquake.
    Beschreibung: Questa trattazione divulgativa è un tentativo di presentare il problema della previsione dei terremoti nella sua globalità per chiarire il significato di “precursore” e la vera utilità dello studio dei precursori. È anche lo spunto per presentare al pubblico le potenzialità del precursore elettromagnetico nel panorama dei precursori classici. Il fatto che i precursori sismici siano fenomeni realmente esistenti non rappresenta la soluzione al problema della previsione deterministica. Attualmente un precursore non è uno strumento di previsione ma un mezzo di sondaggio di ciò che chiamiamo “preparazione del sisma”: il complesso meccanismo di microfratturazione, accrescimento e autoorganizzazione delle fratture che è necessario a produrre la rottura nella crosta. La “teoria della Dilatanza” (TdD) di Scholz, più volte perfezionata dal 1960 ad oggi, resta una delle migliori trattazioni invocabili per motivare l’esistenza dei precursori documentati e sembra tuttora restare l’unica plausibile forma di inquadramento comune. Essa viene qui ripresentata in una visione “estesa” alla luce delle conoscenze geotecniche sulla fratturazione della roccia in laboratorio. La dilatanza è un processo sistematico e necessario rispetto alla rottura della roccia. Sarebbe essa stessa il precursore ideale del terremoto se non mancasse della caratteristica essenziale di essere visibile. Al momento l’unico modo per rilevare la dilatanza in natura è attraverso la sua interazione con l’ambiente circostante e la sua capacità di mutare le caratteristiche fisiche della roccia, cioè attraverso fenomeni secondari che essa può causare. Questi fenomeni, talvolta visibili in superficie, sono ciò che chiamiamo precursori. Abbiamo messo in rassegna i principali precursori “classici” esaminandoli alla luce della TdD. Lo studio della dilatanza, che richiede un monitoraggio comparato, sistematico ed esteso dei fenomeni precursori, potrebbe condurre alla definizione di una chiave interpretativa comune e generale dei precursori stessi per la previsione del terremoto.

    Beschreibung: After the pandemic period due to the spread of COVID-19, staff of the National Institute of Geophysics and Volcanology (INGV) with diversified skills and coming from different geographical areas has planned and organized the participation of the Institute in the XXXVI edition of the Futuro Remoto popular scientific event occurred in Naples from 22 to 27 November 2022, finally back in presence. Starting from the theme indicated by the organizers - called “Equilibrium” - the working group has developed a proposal entitled “Earth: in constant search for equilibrium”. The proposal has been articulated so as to start from the observation of the internal disequilibria that make the Earth a planet in continuous movement, up to the manifestations of the earth’s dynamics producing a significant impact on human life, such as volcanic eruptions, earthquakes and climate changes. These themes have been illustrated with models, demonstrations with scientific instruments, interactive exhibits and videos. Thanks to the activities carried out, the visitors have been able to exchange their points of view with the INGV staff, developing reflections on the proposed topics. Very important for the successful interaction between the INGV personnel involved and the public was the climate of collaboration and harmony created thanks to proactive attitudes, professionalism and skills of the staff who have planned, organized and participated in the event.

    Beschreibung: Communication is not only through words. Man has used any medium to memorize places and describe the area around him through cartography for over 4000 years. By means of new technologies we have passed from computer-drawn maps to georeferenced digital maps, up to georeferenced data shared via webgis. The Osservatorio Vesuviano is the Sezione di Napoli of the Istituto Nazionale di Geofisica e Vulcanologia, a research institution whose main purpose is the monitoring of Campania volcanic areas by means of different types of networks (consisting of fixed and mobile stations), each of which records different parameters. The Osservatorio Vesuviano has built a constantly evolving GIS environment database to manage geographic data in order to remember and understand the distribution of these networks. This paper presents the open access database “moNitoring mAps of camPania voLcanoES” (NAPLES), which provides monitoring networks maps. You can access NAPLES database and download the maps you need both from Osservatorio Vesuviano website or from Zenodo open database.

    Beschreibung: This report describes the state of the art of the installation techniques for seismic stations developed by the Seismology Group and the Seismology Laboratory at the INGV branch in Pisa, with examples of applications taken from long‐duration field experiments carried out in different areas of Tuscany, such as Monte Amiata and the Mugello basin. Our goal was to develop a low‐cost infrastructure, portable and easily adaptable to different terrains, suitable for hosting a variety of real‐time seismic stations. In addition to improving the structural resistance of the deployment, we also developed applications for the remote monitoring of the state of health of the seismic stations, which allowed a more efficient maintenance of the instrumentation. The proposed type of installation has proved to be sufficiently robust and suitable for installations with a temporal duration of a few years, and in agreement with the expected targets, as proved by the analyses carried out during and at the end of the experiments in which they were used.

    Beschreibung: Nel 2018 è stato avviato il progetto FOCUS - Fiber Optic Cable Use For Seafloor Studies Of Earthquake - coordinato da Marc-André Gutscher del Laboratoire Géosciences Océan dell’Università di Brest, in Francia. Questo progetto indaga la sismicità e la struttura crostale del Mar Ionio attraverso l’analisi e l’interpretazione di dati raccolti da strumentazione sottomarina e da reti di monitoraggio disponibili o appositamente installate nelle zone di costa. In tale contesto, l’Osservatorio Nazionale Terremoti (ONT) e l’Osservatorio Etneo (OE), entrambe Sezioni dell’Istituto Nazionale di Geofisica e Vulcanologia (INGV), e il Laboratorio di Sismologia dell'Università della Calabria (UniCal), hanno contribuito al progetto con l’installazione di una rete sismica temporanea lungo la costa ionica calabro-siciliana a integrazione della rete permanente presente nell’area dello Stretto di Messina. La rete temporanea, costituita da 13 stazioni, ha acquisito dal mese di dicembre 2021 al mese di giugno 2023. Nel gennaio 2022, i partner internazionali del progetto FOCUS hanno installato una rete temporanea di sismometri OBS e sensori di pressione per fondali marini. La grande quantità di dati raccolta e la loro integrazione, consentirà di migliorare il monitoraggio sismico e le conoscenze relative alla struttura terrestre dell’area con particolare attenzione alle strutture sismogenetiche con un dettaglio mai raggiunto fino a ora. Tutte le istituzioni coinvolte in FOCUS collaborano per l’acquisizione e l’elaborazione dei dati, l’imaging dell’interno della Terra attraverso l’utilizzo di tecniche avanzate, l’interpretazione e la modellazione dei dati. Il presente lavoro descrive la progettazione, la realizzazione e la gestione della rete temporanea a terra definita FXland, fornendo indicazioni relative sul suo generale funzionamento e sulle caratteristiche del dataset acquisito.

    Beschreibung: A catalogue of precisely located micro-seismicity is fundamental for investigating seismicity and rock physical properties in active tectonic and volcanic regions and for the definition of a ‘baseline’ seismicity, required for a safe future exploitation of georesource areas. In this study, we produce the first manually revised catalogue of micro-seismicity for Co. Donegal region (Ireland), an area of about 50K M2 of on-going deformation, aimed at localizing natural micro-seismic events occurred between 2012 and 2015. We develop a stochastic method based on a Markov chain Monte Carlo (McMC) sampling approach to compute earthquake hypocentral location parameters. Our results indicates that micro-seismicity is present with magnitudes lower than 2 (the highest magnitude is 2.8).The recorded seismicity is almost clustered along previously mapped NE-SW trending, steeply dipping faults and confined within the upper crust (focal depth less than 10 km). We also recorded anthropogenic seismicity mostly related to quarries' activity in the study area.

    Beschreibung: Over the years, seismic anisotropy characterization has become one of the most popular methods to study and understand the Earth’s deep structures. Starting from more than 20 years ago, considerable progress has been made to map the anisotropic structure beneath Italy and the Central Mediterranean area. In particular, several past and current international projects (such as RETREAT, CAT/SCAN, CIFALPS, CIFALPS-2, AlpArray) focused on retrieving the anisotropic structure beneath Italy and surrounding regions, promoting advances in the knowledge of geological and geodynamical setting of this intriguing area. All of these studies aimed at a better understanding the complex and active geodynamic evolution of both the active and remnant subduction systems characterising this region and the associated Apennines, Alps and Dinaric belts, together with the Adriatic and Tyrrhenian basins. The presence of dense high-quality seismic networks, permanently run by INGV and other institutions, and temporary seismic stations deployed in the framework of international projects, the improvements in data processing and the use of several and even more sophisticated methods proposed to quantify the anisotropy, allowed to collect a huge amount of anisotropic parameters. Here a collection of all measurements done on core refracted phases are shown and used as a measure of mantle deformation and interpreted into geodynamic models. Images of anisotropy identify well-developed mantle flows around the sinking European and Adriatic slabs, recognised by tomographic studies. Slab retreat and related mantle flow are interpreted as the main driving mechanism of the Central Mediterranean geodynamics.

    Beschreibung: Nel mese di maggio 2022 è iniziato uno sciame sismico, di breve durata, che ha interessato una piccola area del Chianti fiorentino a circa 15 km a sud dalla città di Firenze. I due terremoti più energetici hanno avuto una magnitudo momento pari a 3.7; nonostante la magnitudo modesta, tali eventi sono stati avvertiti distintamente fino a distanze di diverse decine di chilometri, e hanno destato preoccupazione nella popolazione prossima all’area epicentrale. Inoltre, dato l’ingente patrimonio artistico presente nel capoluogo toscano, questo episodio ha sollevato interrogativi sulla sua vulnerabilità anche a scuotimenti del suolo di piccola entità. Al fine di migliorare le conoscenze sulla ubicazione e le dimensioni delle strutture sismogenetiche attive in prossimità di Firenze, l’Istituto Nazionale di Geofisica e Vulcanologia (INGV) è intervenuto nell’area interessata dallo sciame attraverso il Gruppo Operativo (GO) di emergenza SISMIKO. Il 4 maggio, giorno successivo all’inizio dello sciame, cinque stazioni sismiche mobili sono state installate a distanza ravvicinata dall’area epicentrale, e integrate nel sistema di monitoraggio permanente INGV. Questo lavoro descrive le procedure relative a: (i) l’installazione, la manutenzione e la disinstallazione della rete sismica mobile; (ii) la gestione e il controllo di qualità dei dati acquisiti. Infine, vengono presentate, in riferimento al contesto sismotettonico dell’area, le caratteristiche spaziali e l’evoluzione temporale dello sciame, che ha presentato una piccola ripresa nell’attività sismica ad agosto del 2022, con un terremoto di magnitudo locale 2.7 e successive repliche.
