- 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 - PublicationRestrictedSeismic hazard assessment at Mt. Vesuvius: Maximum expected magnitude(2007)
; ; ; ;Cubellis, E.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Luongo, G.; Dipartimento di Scienze della Terra, Università Federico II, Napoli, Italia ;Marturano, A.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia; ; This paper deals with the problem of seismicity at Mt. Vesuvius with a view to providing an estimation of the maximum expected earthquake. Integrated analysis of both historical and current seismicity as well as the geological conditions of Vesuvius and the surrounding areas show that seismogenetic structures may fall within the crater axis and at the boundaries of the volcanic complex. While activation of the whole seismogenetic volume detected by seismicity in the past 30 years would indicate a total seismic moment of Mo = 7.1E+ 15 Nm for a magnitude M = 4.5, knowledge of the area's geological structure suggests faulting surfaces of about 32 km2 with an associated magnitude of M = 5.4. The areas of maximum expected damage differ according to the orientation of the hypothesized structure. Analysis of geological and geophysical data and the damage associated to the AD 62 earthquake shows that the prevailing directions in the faulting planes are NE–SW in the eastern sector of the volcanic complex, and roughly WNW–ESE in the southern part of the volcano along the coast. Comparison of instrumental seismicity and historical data reveals two significantly different energy levels: a lower earthquake level with Mmax = 4.5, corresponding to current seismicity and that which accompanied volcanic activity in the eruptive period from 1631–1944; an upper level with Mmax = 5.4, represented by the AD 62 earthquake. The two levels correspond to two stress states and different seismogenetic structures.370 45 - PublicationOpen AccessFelt index, source parameters and ground motion evaluation for earthquakes at Mt.

; ; ; ; ; ; ;The Campi Flegrei caldera (Italy) is an active volcanic system characterized by significant long- and short-term ground deformation phenomena ranging the maxima values in the central sector of the caldera, where La Starza marine terrace is located. A detailed study of the La Starza provided crucial clues for understanding the resurgence of the central sector of the caldera following the 15-ka Neapolitan Yellow Tuff eruption. The doming of the caldera floor, marked by two primary episodes of uplift, began soon after the collapse of about 110 m following the eruption. The first doming (15–9.2 ka) occurred as a response to loss of lithostatic loading producing magma influx, possibly regulated by thermal magmatic convection and chaotic movement inside the magma reservoir under the caldera. The calculated ~90 m of structural uplift is the persistent displacement correlated with magma volumes intruded accompanying the contemporaneous volcanic activity. The second episode of uplift (5.5–3.8 ka) produced a ground deformation pattern similar to that measured during recent unrest crises suggesting a stable and shallow (~4-km deep) source of strain like a sill in an elastic half space. By this geometry and inversion of surface deformation, the volume of intruded material was determined. Simply varying pressure history as input, the time history of the surface deformation was reproduced by using spherical source geometry with a concentric viscoelastic shell 8-km deep. The satisfactory comparison between the two models is a useful indication for interpreting the current unrest phase at the Campi Flegrei caldera.73 32 - PublicationOpen AccessTerremoto del 29 dicembre 2013 nel Matese (MW = 5.0).

; ; ; ;Carlino, S.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Cubellis, E.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia ;Marturano, A.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione OV, Napoli, Italia; ; Hystorical data of seismicity at Ischia island (Southern Italy) cover a period of almost 800 years. Since 1228 numerous events exceeded VII MCS degree. The epicentral areas of the earthquakes are located in the northern sector of the island; only one earthquake (1302, VIII MCS degree) was correlated with the latter eruption occurred during 1301-02 AD along the eastern sector of the island. In few cases the earthquakes (1228, 1863, 1881, 1883 AD) were followed by landslides which have produces serious damage while, in average, ground effects (i.e. fractures, capacity and temperature variation of hot springs) were often observed before and after each event. The historical seismicity of Ischia shows the peculiar characteristics of volcanic earthquakes as shallow ipocentral depth (~ 1 km), high intensity, strong directional attenuation of effects and local amplification of damages. At Ischia, the 1883 AD earthquake of “Casamicciola” represents the unique example of modern age earthquake in Mediterranean volcanic area which produced more than 2300 fatalities. The catastrophic effects of this earthquake (Imax=XI MCS degree) covered an area of about 3 km2 in the northern sector of the island, while strong attenuation effects were observed, especially along the south and east directions. From 1883 AD until today a seismic silence in the island has been observed. Some events have been felt from the beginning of the 20th century while, in the last 10 years just few events (M < 2), have been recorded by the INGV-OV surveillance seismic network, localized prevalently in the northern sector of the island. The lack of significant seismicity allow the study of macroseimic data of 1883 earthquake as the fundament issue for hazard assessment, also if considering the increasing of housing density and the high exposed value in the island. Data of earthquake damages and ground effects, obtained by archives sources and literature, have been utilized (also using GIS cross-correlation with geological data) in order to evaluate the tendency of the attenuation for different zones of the island, to detach the contribution of the source from the medium, and define the zones of maximum expected damage.259 327 - PublicationOpen AccessIl Vesuvio e la guerra - Boati e fumo denso sul mare(2014-12)
