    The Seismicity of Ischia Island (2019)
    Details
    Publikationsdatum: 2021-03-09
    Beschreibung: Ischia is a volcanic island, west of the caldera of Campi Flegrei, southern Italy. Since the deployment of a modern seismic network in 1970, until the 21 August 2017 earthquake, the seismicity of Ischia has been characterized by low-magnitude (Md ≤ 2:3) earthquakes located in the northern part of the island, mostly beneath the town of Casamicciola Terme at very shallow depths (∼500 m). Some of these events seem to have occurred on the same seismogenetic structure in the northern part of the island. This area coincides with that where the devastating events of 1881 and 1883 occurred and where the small-magnitude seismicity recorded between 1927 and 1936 was located. The August 2017 seismic sequence affected the same area. The current network configuration is able to locate shallow events with Md ≥ 1:0 and to detect smaller earthquakes or other types of natural and artificial events (e.g., blast fishing, geothermal well explosions; see The Seismic Network section). Here, we present the catalog of earthquakes recorded on Ischia between 1999 and February 2018 and compare the August 2017 seismic sequence with the background seismicity. Furthermore, we identified a sequence of events possibly linked to the explosion of a geothermal well on the island.

    Le attività del gruppo operativo SISMIKO in occasione del terremoto di Ischia Mw3.9 (MD4.0) del 21 Agosto 2017 (2019)
    Details
    Publikationsdatum: 2020-03-24
    Beschreibung: After the MD 4.0 (Mw 3.9) earthquake of August 21 2017 which occurred on the Ischia island, the SISMIKO group [Moretti et al., 2016a; 2016b], which is the coordinating group of the emergency seismic networks of INGV, was activated and four seismic mobile stations were installed in the district of Casamicciola and Lacco Ameno integrated with the permanent network on the island. At the beginning, for the first three months, all the mobile stations, coded as T13 network, acquired locally and were equipped with short period sensors and one accelerometer. Starting from October 2017, the seismic signals for three of the four stations, in separate times from October 2017 to May 2018, were transmitted in real time to the INGV monitoring acquisition room for surveillance purposes. Nowadays, the mobile seismic network on the island is composed by six stations: three of them are telemetered while the others recorded signals on local disks. The seismic stations were equipped with short period sensors LE3Dlite 1Hz, LE3D 5s and FBA-EST Kinemetrics accelerometers. Although starting from September 2017, the seismicity of Ischia island was characterized by few low magnitude earthquakes, the installation of mobile stations T13 improved the performance of the seismic network either for the localization analysis or for the detection of very low magnitude earthquakes.

    The Permanent Monitoring System of the Campi Flegrei Caldera, Italy (2022)
    Springer-Verlag GmbH Germany
    Details
    Publikationsdatum: 2022-02-16
    Beschreibung: 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
    Publikationsdatum: 2023-10-25
    Beschreibung: 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.
