    Description: This work shows the experience acquired by the INGV-Osservatorio Vesuviano GPS Team to study the displacement field at Ischia island. After the last GPS survey, carried out in June 2010, we decided to reorganize and to reprocess the GPS data. The results were integrated with those of the three permanent GPS stations operating on the island. Data quality and repeatability have been evaluated. In order to define the GPS velocity field, we combined multi-year solutions in the period from 1998 to 2010.We defined a local reference system and analyzed the time series for a realistic error estimate. After a description of recent volcanic history and dynamics of Ischia, we describe the data-set, data processing strategy, and finally, some considerations on the achieved results are exposed.

    S.A.G.NET: Rete GPS dell'Appennino meridionale. (2011)
    Istituto Nazionale di Geofisica e Vulcanologia

    Publication Date: 2017-04-04
    Description: The Matese carbonatic massive occupies the northernmost part of the campanian Apennine while Sannio mounts, located to the East of massive, consists primarily of quaternary deposits and represent the area of Apennine chain degrading to East towards the Bradanica foredeep. The area was affected in historical time by several destructive earthquakes. The first ground deformation studies in this area started from 1990-2000 with the definition of geodetic networks, covering all or part of the massive Matese, with the aim of evaluating seismogenic sources responsible for the seismicity of the area. In 2002, a careful inspection of the existing GPS benchmarks was carried out; those which had a good state of preservation and a good level of reliability were included into a new geodetic Matese network, consisting of 38 3D benchmarks. Several surveys were conducted in 2000, 2002 and 2004,with the aim of defining the strain field, defined by plano-altimetric components. In 2005, an intensive work of gathering and validating available data started, integrating data collected by previous surveys with those collected during the new survey carried out in 2006. This work describes in detail the various stages of implementing the final network S.A.G.NET, whose geometry was also bound to the distribution of the known seismogenic sources present in the area. We also show the first results obtained from data collected from2000 to 2006 and the resulting kinematic model for this area.

    NeVoCGPS network: contributions to the Deformation Analysis in Neapolitan Volcanic area based on Continuous GPS measurements (2012)
    Details
    Publication Date: 2017-04-04
    Description: Osservatorio Vesuviano, department of Istituto Nazionale di Geofisica e Vulcanologia, installed a permanent GPS network (NeVoCGPS), constituted of 25 stations, in Neapolitan volcanic area, where three active volcanoes (Somma-Vesuvius, Campi Flegrei caldera and Ischia Island) rise, each characterized by a peculiar type of ground movements activity. The Somma-Vesuvius system exhibits now a low level of ground deformation; the Campi Flegrei, caracterized from over 2000 years by slow up and down vertical movements (bradyseism), at present is in a very slow uplift phase; Ischia, finally, shows subsidence in the specific areas (Southern and North-West sectors of the island). The presence of these volcanoes and the dense urbanization of the area make the ground deformation monitoring a crucial point for risk mitigation and modelling aims. The 3D ground displacements are calculated using CGPS data, acquired with a 30s rate and with the daily and weekly vertexes position estimate. All the stations are managed by remote control and the data are automatically downloaded and processed using Bernese software package. The entire chain of acquisition, processing and data analysis is accurately described and some results obtained in the last years are shown.
