    Beschreibung: Ground deformation monitoring of active volcanoes is used routinely to determine phases of volcano unrest and can provide insights in the evolving plumbing system of a volcano and the influence local tectonics structures have on the volcano tectonic evolution of the volcanic edifice. Volcanic deformation analysis can be performed using velocity and direction measurements of the ground surface using Global Navigation Satellite System (GNSS). In this study, we perform two-dimensional deformation analyses of pre‑ and post‑eruptive phases with the scope of determining the strain before and after an eruptive phase at Mt. Etna Volcano (southern Italy) during 2004‑2006. In order to do so, we analyse the GNSS displacement data from Mt. Etna between 2004‑2005 and 2005‑2006 using the dedicated SSPX software. The extention, dilation and rotation maps of the study area were determined. The contraction and volumetric decrease concomitant the 2004‑2005 effusive eruptive period and extension and volumetric increase for the 2005‑2006 data series were observed. The deformation on the northeast part of Mt. Etna Volcano, which showed different characteristics with respect to its surroundings, was thought to be conditioned by the dynamic of the Pernicana fault system. Additionally, Complete Spherical Bouguer (CSB) gravity anomaly and the gravity gradient tensors were calculated giving insight on the subsurface structures of Mt. Etna Volcano and its surroundings.

    Beschreibung: In questo lavoro viene descritta la sismicità, collegata agli eventi vulcanotettonici, registrata dalle stazioni della Rete Sismica Permanente dell’INGV – Osservatorio Etneo (OE) nell’area vulcanica del Monte Etna dall’1 gennaio al 31 dicembre 2020. Nel periodo di riferimento la rete sismica gestita dall’INGVOE risulta costituita da un centinaio di stazioni i cui segnali sismici sono trasmessi in tempo reale al CUAD (Centro Unificato Acquisizione Dati) di Catania dove vengono acquisiti e trasferiti in continuo alla Sala Operativa dell’Osservatorio Etneo. Nel corso del 2020 sono stati registrati 3604 terremoti, di cui 2287 localizzati dal Gruppo di Lavoro Analisi Dati Sismici dell’OE (GLAOE), secondo gli standard definiti per la compilazione del catalogo strumentale nell’ambito delle attività di monitoraggio previste all’interno dell’Accordo Quadro INGV – Dipartimento Protezione Civile (DPC) 20122021 (Allegato A). Le profondità focali degli eventi analizzati sono comprese tra 1.6 e 35 km circa, mentre la magnitudo locale (ML) risulta compresa tra 0.2 e 3.7; la magnitudo di completezza (MC) del risultante catalogo è pari a 1.2 (± 0.01), valore quindi del tutto confrontabile con quello stimato per il 2017 e il 2019, ma superiore di 0.1 unità rispetto a quello stimato per il 2018. Sono 15 gli eventi con ML ≥ 3.0 registrati nel corso del 2020, la maggior parte dei quali appartenenti alle 11 sequenze sismiche che sono state individuate per lo stesso anno. La sequenza sismica più importante sia per numero di eventi (21) sia per energia rilasciata (valore massimo ML = 3.7), è stata registrata il 31 dicembre a partire dalle 19:59 (UTC) e ha interessato il medio versante meridionale dell’edificio vulcanico, poco a nord del centro abitato di Ragalna.

    Beschreibung: Vulcano is one of the seven volcanic islands composing the Aeolian Islands archipelago (Southern Italy), which also includes three other active volcanoes. The island was orig-inally a stratovolcano like Stromboli; afterwards, its shape turned towards a complex structure composed of several volcanic landforms of different sizes. This is due to the great variability of the tectonic and volcanic phenomena, presently showing a volcano made by two calderas, a lava dome complex and two small active cones. The largest of them is the tuff cone of La Fossa, hosted in the middle of a 3- km-wide caldera struc-ture (La Fossa caldera), whose borders are visible on the southern and western sides of the island. Its last eruption occurred in 1888–1890. At present, Vulcano is charac-terized by weak shallow seismicity and intense fumarolic activity mainly concentrated within the crater of the La Fossa cone and along its rims during a recent unrest phase started in 2021, and measured with a multiparametric monitoring network.

    Beschreibung: Digital Surface Model and the orthophoto availabe at https://www.pi.ingv.it/banche-dati/Stromboli-2023-UAS-Survey/
    Beschreibung: Stromboli is a volcanic island in a persistent state of activity, located in the Tyrrhenian Sea off the northern coast of Sicily. During the night of 25 and 26 May 2022, a massive human-caused wildfire destroyed most of the vegetation cover on the NE flank of the island, just above the main village. On 12 August 2022, a particularly heavy rainfall event remobilized the loose volcaniclastic deposits that covered the burned volcanic flank, no longer protected by the vegetation. This event triggered several debris flows that were channeled by the roads and flooded several streets and buildings, causing severe damage to the village. In late-March 2023, just before the large spring vegetation growth, we conducted an Unmanned Aerial System (UAS) photogrammetric campaign over a sector of the NE flank of Stromboli Island, to acquire data on an area massively affected by the wildfire first and by the debris flows later. Here we present and share with the scientific community and civil authorities the results of this UAS campaign, which consists of a 1.4 km2 wide 10 cm-resolution Digital Surface Model (DSM) and 1.6 cm-resolution orthomosaic. These data clearly show the dramatic consequences of the 2022 tragic events at Stromboli. We also produced an elevation difference map by comparing the 2023 DSM here generated and the 2012 LiDAR DEM to provide a first overview of the thickness of the deposits that were removed from the Stromboli NE flank.

    Beschreibung: The “Giornata ONT 2023” arises from the will to let know within INGV how many activities do people from the Osservatorio Nazionale Terremoti (ONT), and how strong is their contribution to the INGV missions: Research, Services, Education, Communication. In the nearly seven years of the current management the ONT has experienced a continuous evolutionary, sometimes complex, path. But it is always a straight path to pursue the objective of a continuous growth of the ONT. During these years the ONT has changed its name (from Centro Nazionale Terremoti – CNT, to ONT); it has experienced the coming out of some employees that moved to create the Irpinia new Section; it has lived the novelty of incoming people (example from the Centro Allerta Tsunami). It has also faced the need to overcome the limitations due to the worldwide pandemic emergency COVID19, either for the h24 services or for the research activities. Therefore in 2020 and 2021 we have only remotely attended the ONT days. The drive to be “in presenza” comes from this latter issue. We strongly want to meet, to talk face to face, to “Welcome” the young colleagues who are the injection of new ideas and perspectives, that are the necessary fuel to evolve the knowledge. As a matter of fact it emerges from the DNA of the ONT, i.e. the inclusiveness and the multidisciplinarity. This latter is widely testified by the ONT activities that are shared among the three Departments and their strategic objectives. The agenda of the “Giornata ONT 2023” has specifically emphasized the variety of the technical and scientific contents, that for sake of simplicity have been collected in the following themes: • Infrastructures, Data­Sharing and Laboratories • Analysis, Modelling, Interpretation of Geophysical Phenomena • National and International Projects (Research Results and Products from Completed Projects; Ongoing Projects) • Society ­ Communication, Dissemination, Emergency Management • Seismic Surveillance And Tsunami Warning Overall, the contributions have been 100, most of which are posters (77) and the remaining (23) in different exhibit formats. The wide interest about the proposed contents and the positive feedback from the attendance, pushed the decision to collect and publish the contributions in a Miscellanea INGV, where the documents can be easily found. And we are finally ready to make the Miscellanea available to the reader. I would warmly thank the Authors for their enthusiastic acceptance to contribute, the Conveners of the “Giornata ONT 2023” Sessions for their availability to organise and manage the submitted poster/exhibits, the Editorial Board members for their hidden work that led to this Miscellanea. In conclusion, let me spend a few words about my personal journey as Director of the ONT. After 2504 days it has come to an end and the “Giornata ONT 2023” and the Miscellanea are, somehow, the cherry on top. It is really difficult to say “Thanks” one by one to the people who helped me along this complex and long path. So, please, let me simply say Grazie a tutti voi! Salvatore Stramondo - Director ONT (2017-2023)
