    Description: 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.

    Description: 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.

    Description: 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.

    Description: 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.

    Description: 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.
    Description: 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.

    Description: The seismic monitoring of the national territory and of the EuroMediterranean area makes use of the velocimetric, accelerometric and GPS (geodetic) data acquired by the stations of the National Seismic Network, by the RING Network and by the MedNet Network. As part of the FISR 2017 project “Integrated operating rooms and monitoring networks for the future: INGV 2.0” (2017), sensors capable of detecting both geophysical and geochemical parameters at the same time are being integrated. This technical report describes the integration of a Rn222 sensor (radon hereafter). Over the past few decades radon has found a variety of Earth Science applications, ranging from its use as a potential earthquake precursor and tectonic stress indicator to its specific role in volcanic environments, where significant changes in concentration previous or concomitant to eruptive crises are also induced by volcanic gases, CO 2 for example, which act as carriers accelerating the migration of radon through the earth’s crust and therefore its detection. In order to explore the possibility of a link between seismogenic processes and temporal variability of radon emissions, a permanent national network has been created, IRON (Italian Radon mOnitoring Network), which uses both commercial radon instruments, equipped with a proprietary system for data storage, transmission and consultation, and INGV sensors that need an interface to acquire and make data available remotely. A hardware and software interface has therefore been designed, built and tested capable of i) counting and storing the pulses in TTL format generated by the instrument which measures the 8 radon concentration in air, ii) being connected to a router for sending the acquired data to a server. A service (syncproc) was also created in PHP to query remote stations at regular intervals and collect the acquired data intended to populate a database created with MariaDB. An expressly created website allows to extract the stored data from the database and configure each installed sensor. The various software elements have been designed using open source resources.

    Description: 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.

    Description: 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.

    Description: 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.

    Description: The latest version of the CPTI15 seismic catalogue (January 2022) includes more than two hundred earthquakes marked AMGNDT95. Their parameters are derived from expeditious studies produced as part of the GNDT/CNR ‘Hazard Project’ (1993-1995). Some of them simply parameterise data taken from bibliographic references in the PFG85 catalogue, i.e., mostly Mario Baratta’s seismological compilation “I terremoti d’Italia” [1901] or twentieth-century seismological bulletins. Others go back as far as the original sources of the references themselves. As part of the B2 Convention between INGV and DPC (2016-2021), a review of these earthquakes was initiated, starting with the most relevant ones, for which a good margin of improvement in knowledge can be assumed. At the same time, first-level research was also begun on a dozen or so earthquakes of low energy, but still above the damage threshold, which for various reasons had never been studied so far and whose parameters in the CPTI15 are still those of the POS85 catalogue. We present here the results of the study of about thirty earthquakes belonging to both categories. The overall result is generally a strong improvement of the available information, from which it will be possible to derive epicentral parameters more up-to-date and more robust than the previous ones.
