    Improvement and development of the tiltmetric monitoring networks of Neapolitan volcanoes (2019)
    Details
    Publication Date: 2019-04-02
    Description: The goal of this work is to illustrate the technological development of the tiltmetric monitoring network of Osservatorio Vesuviano, since 1986, retracing the technical steps that led to the current network configuration. This network is devoted to the monitoring of the three Neapolitan volcanoes: Vesuvius, Phlegrean Fields and Ischia Island, which are widely recognized among the volcanic areas with the highest risk worldwide. Ground tilt monitoring had to face numerous technical obstacles, mainly due to background noise characterizing densely urbanized areas like the Neapolitan volcanoes. The network started with the first installations of horizontal optical pendulums that recorded analog signals. In the following years, the network was equipped with electronic sensors more handy and easy to install. A technological leap forward occurred when the first digital sensors were installed in deep boreholes, allowing them to record tilt signals not affected by thermal disturbances. These data are digitally acquired and managed by a datalogger for the data storage and exchange. Currently the network consists of 10 sensors in Phlegrean Fields, 8 in Vesuvius and 3 in Ischia Island, making it one of the densest tiltmetric volcano monitoring network worldwide. This network can boast a database containing thirty years of data acquired by both analog and digital stations. Data consists of both ground and meteorological signals, such as temperature and atmospheric pressure. In these areas they allow a continuous monitoring of the temporal variations of the ground tilt with important implications in understanding the dynamics of these active volcanoes.

    Geophysical monitoring of Stromboli volcano: insight into recent volcanic activity (2019)
    Details
    Publication Date: 2019-10-18
    Description: Stromboli is an open conduit strato-volcano of the Aeolian archipelago (Italy), characterized by typical Strom-bolian explosive activity, lasting for several centuries, and by the emission of huge amounts of gas. The normalactivity of Stromboli is characterized by some hundreds of moderate explosions per day. Major explosions, whichlaunch scoria up to hundreds of meters from the craters, lava flows and paroxysmal explosions, which producelarge ballistic blocks, sometimes take place. During the effusive eruption in 2002 - 2003, which caused a tsunamiwith waves of about 10 meters high along the coasts of the Island, the monitoring system was enhanced. In 2006INGV has added two Sacks-Evertson borehole volumetric dilatometers to the surveillance system, in order to mon-itor changes in the local strain field by measuring areal strain. Today we have a large amount of geophysical dataand observations that allow us to better understand how this volcano works. After a period of low explosive activitystarted in mid-2014, Stromboli has shown a more intense explosive activity in the last few months. During the re-cent phase of increased activity, the geophysical monitoring system detected four major explosions occurred on 26July, 23 October, 1 November and 1 December 2017, respectively. The current phase of reawakening of Strombolivolcano has led the Italian civil protection authorities to decree the "attention" alert level (yellow) on the Island.

    The real-time multiparametric network of Ischia (2019)
    Details
    Publication Date: 2019-10-18
    Description: Ischia is an active volcanic complex, which erupted the last time in 1302. Its recent geological history is dominated by the earthquake of 1883, which seriously affected Casamicciola Terme, and the other municipalities of the island. On 21st Agust 2017, the Md=4.0 earthquake located below the town of Casamicciola Terme addressed the media attention to this volcanic island that was seismically monitored since 1885 by Giulio Grablovitz (1846-1928) who installed a seismic tank (an instrument capable of measuring and recording on paper the oscillations of the water contained in a tank, with respect to the ground) in the Casamicciola Observatory. The Osservatorio Vesuviano is the INGV division charged of the Ischia monitoring. The first seismic station was installed in Casamicciola Observatory in 1993 and since then the seismic monitoring of the island is going up. The real time monitoring of this volcanic island involves several geophysical fields and the data are transmitted by a wide data-communication wired on radio infrastructure to the Monitoring Centre of Osservatorio Vesuviano: - The seismic network counts of 4 station sites with velocimetric, accelerometric and infrasonic sensors. The data are sent in real time to the Monitoring Centre. - The GPS network counts of 6 stations located on the island. All the procedures for remote stations managing (raw data downloading, data quality control and data processing) take place automatically and the computed data are shown in the Monitoring Centre. - The tiltmetric network consist of 3 digital borehole stations distributed around the island. Each tiltmetric station is equipped with a temperature and magnetic sensor.

    The real-time multiparametric network of Campi Flegrei and Vesuvius (2019)
    Details
    Publication Date: 2019-11-05
    Description: Volcanic processes operate over a wide range of time scale that requires different instruments and techniques to be monitored. The best approach to survey a volcanic unrest is to jointly monitor all the geophysical quantities that could vary before an eruption. The monitoring techniques are sometimes peculiar for each volcano, which has its own behavior. The simultaneous investigation of all the geophysical and geochemical parameters improves the sensibility and the understanding of any variation in the volcanic system. The Osservatorio Vesuviano is the INGV division charged of the Campi Flegrei and Vesuvius monitoring, two of the highest risk volcanic complexes in the world due to the large number of people living on or close to them. Each of them have peculiarities that increase the monitoring challenge: Campi Flegrei has high anthropic noise due to people living within its numerous craters; Vesuvius has a sharp topography that complicates the data transmission and analysis. The real time monitoring of the two areas involves several geophysical fields and the data are transmitted by a wide data-communication wired or radio infrastructure to the Monitoring Centre of Osservatorio Vesuviano: - The seismic network counts of 20 station sites in Campi Flegrei and 23 in Vesuvius equipped with velocimetric, accelerometric and infrasonic sensors. Some of them are borehole stations. - The GPS network counts of 25 stations operating at Campi Flegrei caldera and 9 stations at Vesuvius volcano. All the procedures for remote stations managing (raw data downloading, data quality control and data processing) take place automatically and the computed data are shown in the Monitoring Centre. - The mareographic network counts of 4 stations in the Campi Flegrei caldera coast and 3 close to the Vesuvius that transmit to the Monitoring Centre where the data are elaborated. - The tiltmetric network consist of 10 stations distributed around Pozzuoli harbor, the area of maximum ground uplift of Campi Flegrei, evidenced since 2005, and 7 stations distributed around the Vesuvius crater. Each tiltmetric station is also equipped with a temperature and magnetic sensor. The signals recorded are sent to the Monitoring Centre. - The 4 marine multiparametric stations installed in the Pozzuoli gulf send accelerometric, broad band, hydrophonic and GPS data to the Monitoring Centre. - The geochemical network counts of 4 multiparametric stations in the fumarolic areas of Campi Flegrei and 2 stations in the Vesuvius crater (rim and bottom) with data transmission to the Monitoring Centre. They collect soil CO2 flux, temperature gradient and environmental and meteorological parameters and transmit them directly to the Monitoring Centre. - The permanent thermal infrared surveillance network (TIRNet) is composed of 6 stations distributed among Campi Flegrei and Vesuvius. The stations acquire IR scenes at night-time of highly diffuse degassing areas. IR data are processed by an automated system of IR analysis and the temperatures values are sent to the Monitoring Centre

    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.
