- PublicationRestrictedThe last Vesuvius eruption in March 1944: reconstruction of the eruptive dynamic and its impact on the environment and people through witness reports and volcanological evidence(2016)
; ; ; ; ; Mount Vesuvius last erupted in March 1944. The eruption began with a modest effusive activity (18–21 March, phase I) and then moved on to a lava-fountain phase (21–22 March, phase II) that quickly culminated in a 24-h paroxysmal phase (22–23 March, phase III), during which the eruptive column reached its maximum altitude and ash carried by the wind was deposited at distances of up to 500 km from the volcano. Subsequently (phase IV), the ash cloud reached altitudes not exceeding 2 km above the crater and the explosions became discontinuous, alternating with frequent tremors. From April 7th the vent remained permanently closed. Since then, the current period of quiescence may be said to have begun. In our study we present a detailed geochemical study of the volcanic products emitted throughout the stages of the eruption, including an extreme distal ash sample, collected at the time of the eruption in Albania (Devoli) by the geologist Antonio Lazzari. The results indicate that magmatic differentiation took place in two crystallization stages under different temperature and pressure. Moreover, through the use of a numerical model of volcanic ash dispersion in the atmosphere as well as the collection of new witness accounts, we inferred the maximum height reached by the eruptive column (>8–10 km above the crater) as well as its impact on the environment and people, suggesting that the damage in the area and even the number of the victims could be higher than accepted until now.609 5 - PublicationOpen AccessCampi Flegrei, Vesuvius and Ischia Seismicity in the Context of the Neapolitan Volcanic Area(2021)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; Studying seismicity in a volcanic environment provides important information on the state of activity of volcanoes. The seismicity of the Neapolitan volcanoes, Campi Flegrei, Vesuvius, and Ischia, shows distinctive characteristics for each volcano, coveringwide range of patterns and types. In this study we relocated some significant volcano- tectonic earthquake swarms that occurred in Campi Flegrei and Vesuvius. Moreover, we compared the earthquake occurrence evolution, the magnitude and the seismic energy release of the three volcanoes. Also, we considered the results of seismic analysis in the light of geochemical and ground deformation data that contribute to defining the state of activity of volcanoes. In Campi Flegrei, which is experiencing a long term unrest, we identified a seismogenic structure at shallow depth in Pisciarelli zone that has been activated repeatedly. The increasing seismicity accompanies an escalation of the hydrothermal activity and a ground uplift phase. At Vesuvius a very shallow seismicity is recorded, which in recent years has shown an increase in terms of the number of events per year. Earthquakes are usually located right beneath the crater axis. They are concentrated in a volume affected by the hydrothermal system. Finally, Ischia generally shows a low level of seismicity, however, in Casamicciola area events with a moderate magnitude can occur and these are potentially capable of causing severe damage to the town and population, due to their small hypocentral depth (typically < 2.5 km). After the seismic crisis of August 21, 2017 (mainshock magnitude M 4), the seismicity returned to a low level in terms of occurrence rate and magnitude of earthquakes. The seismicity of these three different volcanic areas shows some common aspects that highlight a relevant role of hydrothermal processes in the seismogenesis of volcanic areas. However, while the main swarms in Campi Flegrei and most of the Vesuvian earthquakes are distributed along conduit-like structures, the seismicity of Ischia is mainly located along faults. Furthermore, the temporal evolution of seismicity in Neapolitan volcanic area suggests a concomitant increase in the occurrence of earthquakes both in Campi Flegrei and Vesuvius in recent years.2280 73 - PublicationOpen AccessEarthquake, GIS and multimedia.

G.; Servizio Sismico Nazionale, Roma, Italy ;Rebuffat, M.; Osservatorio Vesuviano, by Servizio Sismico, Roma, Italy ;Soddu, P.; Servizio Sismico Nazionale, Roma, Italy; ; ; ; ; A series of multimedia monographs concerning the main seismic events that have affected the Italian territory are in the process of being produced for the Documental Integrated Multimedia Project (DIMP) started by the Italian National Seismic Survey (NSS). The purpose of the project is to reconstruct the historical record of earthquakes and promote an earthquake public education. Producing the monographs. developed in ARC INFO and working in UNIX. involved designing a special filing and management methodology to integrate heterogeneous information (images, papers, cartographies, etc.). This paper describes the possibilities of a GIS (Geographic Information System) in the filing and management of documental information. As an example we present the first monograph on the 1883 Casamicciola earthquake. on the island of Ischia (Campania, Italy). This earthquake is particularly interesting for the following reasons: I) historical-cultural context (first destructive seismic event after the unification of Italy); 2) its features (volcanic earthquake); 3) the socioeconomic consequences caused at such an important seaside resort.302 452 - PublicationOpen AccessGiuseppe Mercalli da Monza al Reale Osservatorio vesuviano: una vita tra insegnamento e ricerca. contributi presentati per l’inaugurazione dell’anno mercalliano(INGV, 2014)

The lithosphere strain partitioning is part of the seismic cycle. We present the first GPS kinematic pattern obtained during the interseismic phase by a dense episodic GPS network, the Southern Apennine Geodetic Network - SAGNet (Sepe et al., 2009), in the time span 2002-2013. This network is located across the transition zone between central and southern Apennine, including Meta-Mainarde-Venafro and AltoMolise-Sannio-Matese mounts. This region is characterized by seismogenic fault systems responsible, in the past, for several destructive earthquakes of intensity I ≥ IX MCS and, in more recent years, characterised mainly by some moderate magnitude seismic sequences (max magnitude Mw 5.0, December 29 2013) and single small events (Ml < 2.5).SAGNet GPS data were processed by BERNESE sw v.5.0 and the resulting velocities were least-squares combined with the permanent stations velocity field and with the velocity solution of Giuliani et al. 2009. The combined GPS velocity field, shows a perpendicular maximum extension with respect to the Apennine chain of about 2.0 mm/y.The Matese area was hit on December 29, 2013 by a Mw=5.0 (Convertito et al., 2016) earthquake. It was followed by an intense seismic activity until the beginning of February 2014. After the mainshock a GPS survey was carried out on the SAGnet stations. We collected data from 2013, 30 December to 2014, 4 April. The time series of 17 stations are affect by an offsets on the linear drift. The map of horizontal coseismic displacements (Figure 3) shows a sub-radial displacement shape with respect to the epicentre. Larger displacements are observed in correspondence of NE portion of the Matese massif. Considering the Matese Lake Fault as the probable source of the mainshock (dip 65°, strike 116, rake 270 – MLF, Ferranti et al, 2015), we found that the Okada modelling does not fit the observed displacements and only a small fraction of displacements are resolved with a simple slip.Figure 4 resembles the results of previous studies compared with our GPS analysis. We considered seismological analyses, tomographic models, degassing of CO2 data and conceptual model of processes recognized in South Apennine (L. Bisio, et al., 2004; Chiarabba and Chiodini, 2013; Improta et al., 2014; Ventura et al., 2007, R. Di Stefano and M.G. Ciaccio, 2014; Ferranti et al., 2015; Convertito et al., 2016;). The GPS results indicate that the relative motion between Eurasia and Adria plates is responsible of the active deformation in the Apennines. The most important outcomes of this study are: (i) During the interseismic phase the differential motion between Adriatic and Tyrrhenian domains seems to be accommodated in a narrow belt bordering the westward flank of the Sannio Mts, showing a 2 mm/y extension. (ii) The maximum extension does not follow the topographic high of the chain but is shifted toward the eastern outer belt. (iii) No significant GPS deformation is highlighted in correspondence of major and known fault systems where the GPS velocities appear almost steady. We propose that the observed coseismic displacements are only marginally explained by a slip on the MLF fault. The vertical directivity and depth distribution of the seismic sequence (Convertito et al., 2016), the vertical and horizontal heterogeneity of lower crust and upper mantle (Bisio et al., 2004; Di Stefano and Ciaccio, 2014), the high flux of CO2 degassing (Ventura et al., 2007, Chiarabba e Chiodini, 2013 ), the probable presence of pressurized CO2 bodies fed by fluids uprising from the mantle wedge (Improta et al.,2014 ), suggest instead that the seismic sequence could be caused by sub-vertical cracks that originate at the Moho interface and reach the bottom of the seismogenic layer (10km depth).185 136 - PublicationOpen AccessTerremoto del 29 dicembre 2013 nel Matese (MW = 5.0).
