    The Permanent Monitoring System of the Campi Flegrei Caldera, Italy (2022)
    Springer-Verlag GmbH Germany
    Details
    Publication Date: 2022-02-16
    Description: We present the main features of the permanent monitoring system managed by the Istituto Nazionale di Geofisica e Vulcanologia-Osservatorio Vesuviano in the Campi Flegrei caldera. Eruptive history of this active volcano shows that the majority of the eruptive events has been characterised by high explosivity and was accompanied by pyroclastic density currents. Its last eruption occurred in AD 1538 and in the next centuries the Campi Flegrei caldera has experienced several episodes of bradyseism and also the progressive increasing of the urbanisation in the area (west of Naples). Monitoring the dynamics of a mainly explosive volcano completely embedded in a very populated area is a challenging task. In order to detect any variation in the physical and chemical parameters of the Campi Flegrei caldera, the Istituto Nazionale di Geofisica e Vulcanologia-Osservatorio Vesuviano manages a permanent multi-parametric monitoring system. All the recorded h24 continuous data are transmitted to the Monitoring Room of the Osservatorio Vesuviano in Naples, where they are acquired, processed and evaluated to define changes in the dynamical state of the volcano. The caldera, since the end of 2004, is experiencing a bradyseismic episode characterised by a low velocity rate uplift, low energy earthquakes and increasing in the magmatic components of fumarolic fluids. The monitoring and surveillance activity of the Campi Flegrei caldera plays a crucial role in the volcanic emergency plan that includes evacuation of approximately 500,000 people before the beginning of the eruption.

    Muon radiography applied to volcanoes imaging: the MURAVES experiment at Mt. Vesuvius (2021)
    IOP
    Details
    Publication Date: 2023-10-25
    Description: Abstract: Muon radiography is a technique based on the measurement of absorption profiles of muons as they pass through matter. This measurement allows to obtain an image of the inner structure of large volume objects and is suitable to be applied in several fields, such as volcanology, archaeology and civil engeneering. One of the main applications concerns the study of volcanic structures; indeed it is possible to use this technique to measure the mass distribution inside the edifice of a volcano providing useful information to better understand the possible eruption mechanisms. The MURAVES (MUon RAdiography of VESuvius) project aims to the study of the summital cone of Mt. Vesuvius near Naples in Italy, one of the most dangerous active volcanoes in the world. The MURAVES apparatus is a modular, robust muon hodoscope system with a low power consumption, optimized to be used in inhospitable environments like the surroundings of volcanoes. The complete detection system is an array of identical tracking modules, each with an area of 1 m2 , based on the use of plasic scintillators. The technologies, the status and the data analysis strategy of the experiment will be presented in this paper.

    Muography of the Volcanic Structure of the Summit of Vesuvius, Italy (2023)
    Whiley-AGU
    Details
    Publication Date: 2023-01-25
    Description: In the context of recent developments in volcanic muography, we describe an experiment at Vesuvius, the volcano near Naples that destroyed Pompeii and Herculaneum (Italy) in 79 AD. This volcano is about 1200\,m high with a typical summit caldera formed by Mount Somma. Vesuvius is among the highest-risk volcanoes in the world due to its highly explosive eruptive style and the high population density of the area where it is located. Volcanoes are generally fragile geological structures, prone to produce partial collapse and large landslides that can affect the style of eruptions. Moreover, the knowledge of the internal structure is fundamental for understanding past eruption activity and for constraining eruption models. For these reasons, studying the internal structure of the ``Gran Cono'' (great cone) of Vesuvius and the physical characteristics of its rock is important and led us to design a muography experiment at Vesuvius. This experiment, which is currently in progress, is based on three scintillator detectors with a surface of 1\,m$^2$ each. These detector features have been implemented to overcome the problems related to the large thickness of rock that form the ``Gran Cono'' of Vesuvius and the effects that can be a source of error in data processing. These aspects represent an open challenge for the muography of large volcanoes, which today constitutes the frontier of research in the field of volcanic muography.
