    The RING network: improvements to a GPS velocity field in the central Mediterranean (2010)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: Since 2004, a continuous Global Positioning System (GPS) network has been operated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) to investigate active tectonic processes in Italy and the surrounding regions, which are still largely debated. This important infrastructure is known as Rete Integrata Nazionale GPS (RING) network, and it consists of about 130 stations that are deployed all over Italy. The development and realization of a stable GPS monumentation, its integration with seismological instruments, and the choice of both satellite and internet data transmission, make this network one of the most innovative and reliable CGPS networks in the world. The technologically advanced development of the RING network has been accompanied by the development of different data processing strategies, which are mainly dependent on the use of different GPS analysis software. The different software-related solutions are here compared at different scales for this large network, and the consistency is evaluated and quantified within an RMS value of 0.3 mm/yr.

    Recent terrestrial and satellite observations to model deformations at Colli Albani volcano (central Italy) (2012)
    Springer Verlag New York Inc
    Details
    Publication Date: 2017-04-04
    Description: The Colli Albani volcanic complex (Rome, Italy) has been dominated by episodic eruptions commencing around 561 ka and ending with the most recent activity of the Albano maar phase (\70 ka). Earthquakes of moderate intensity, gas emissions and significant ground deformations are the recent evidences of a residual activity. Former geodetic data from leveling surveys, GPS stations and InSAR observations tracked ongoing significant uplift of the order of few mm/year near the Colli Albani western flank. Different uplift rates were detected by each technique in different time spans, suggesting also the possibility of sporadic recharge of the hydrothermal system. The renewed high precision leveling data from IGMI survey carried out in 1997/1999 and the last leveling survey carried out in 2006 show that the uplift along the route is currently significant at an average rate of *3 mm/year. Radar interferograms from ALOS satellite show uplift rate of *6 mm/year, southwest of the central sector of the leveling route. We have undertaken a joint inversion of the various geodetic data (vertical rates from leveling surveys, GPS site velocities and InSAR observations acquired by ALOS satellite) using a nonlinear inversion technique to estimate the parameters of a point-pressure source, possibly capable of explaining the ongoing deformation at Colli Albani volcano.

    The interseismic velocity field of the Central Apennine from a dense GPS network (2012)
    Details
    Publication Date: 2017-04-04
    Description: Since 1999 we have repeatedly surveyed the Central Apennines by means of a dense survey style geodetic network (CAGeoNet) consisting in 123 benchmarks distributed in an area of ~180 x 130 km extended from the Tyrrhenian Sea to the Adriatic Sea with an average inter-site distance of 3-5 km. The network is located across the main seismogenic structures of the region, able to generate destructive earthquakes. Here we show the horizontal GPS velocity field of the CaGeoNet and the available continuous GPS (CGPS) stations in this region, that are estimated from their position time series in the time span 1999-2007. Data have been analyzed using Bernese and Gamit software and the two solutions have been rigorously combined to minimize software-dependent systematic errors. We analyze the strain rate field, which shows a region characterized by extension located along the axis of the Apennines chain, with values ranging from 2 to 66 10-9 yr-1 and a relative minimum of 20 10-9 yr-1 located in the L’Aquila basin area. Our velocity field represents an improved estimation of the ongoing elastic inter-seismic deformation of central Apennines in particular of the L’Aquila earthquake of April 6th, 2009 area.

    The INGV-CNT crustal motion map for the Euro-Mediterranean region (2015)
    Details
    Publication Date: 2017-04-04
    Description: Several thousands GPS/GNSS permanent stations, managed by both scientifc and cadastral institutions, are now available on the European plate and its boundaries. Data coming from these stations provide unprecedented spatial and temporal coverage of time-dependent deformation signals essential to understand the fundamental physics that govern tectonic deformation and faulting. The National Earthquake Center (Centro Nazionale Terremoti, CNT) of the National Institute of Geophysics and Volcanology (Istituto Nazionale di Geofisica e Vulcanologia, INGV) in Italy, is the Italian leader institution for the collection, management and scientific analysis of Global Positioning Systems (GPS) measurements. Distinct analysis centers independently and routinely process and analyze data using high-quality geodetic software (Bernese, Gamit, Gipsy) to measure the movements of 〉1000 points spanning the Eurasian plate and its boundaries. The goal of this project is to offer high-quality geodetic products, increase their accessibility to the European scientific community and promote the inter-disciplinary data exchange through a multi-level, user-friendly data gateway. These activities will be performed in strict contact with the GNSS Working Group of the EPOS project (http://www.eposeu.org) that is proposing to integrate, archive and distribute data, metadata and products for available GNSS stations on the European plate.

    MONITORING AND MODELLING HYDROTHERMAL PANAREA SYSTEM (AEOLIAN ISLAND): GPS AND VOLCANOLOGICAL DATA (2008)
    Details
    Publication Date: 2019-10-10
    Description: In November 2002 a submarine gas eruption started offshore 3 Km east of Panarea island (Aeolian Island) on top of a shallow rise of 2.3 km2 surrounded by islets forming a small archipelago. This event has posed new concern on a volcano generally considered extinct. Panarea island and its archipelago (~ 3.3 km2) are the emergent portion of submarine stratovolcano more than 2000 m high and 20 Km across; exhalative activity due to a shallow hydrothermal system is well known since historical times. To monitor and study ground deformation associated with anomalous gas emission, a local GPS network (PANAREA) was designed, set up and measured during time span December 2002 - October 2006. The network consists of nine sites (six constructed after 2002) located on Panarea and on the islets. GPS data analysis was performed combining episodic campaigns of Panarea and other local networks located in the Aeolian area, carried out between 1995 and 2006, and data of continuous European and Italian sites. The results show at Panarea volcano two distinct crustal domains characterized by different kinematics and styles of deformation. The merging of GPS and structural data suggest the relationship among gas vent distribution, submarine volcanological structures and ground deformations. The actual distribution of the estimated strain-rate is consistent with the structural setting.The general subsidence and shortening in the islets area can be interpreted as the response of the surface to the variation of the hydrothermal system reservoir which is progressively reducing its pressure after the gas eruption. A simple first order approach to the modelling of the hydrothermal system is the use of Okada sources.To evaluate the coupled thermo-hydro-mechanical processes going on in Panarea, a two-step model will be implemented. The model first involves the simulation of pore pressure and temperature changes due to fluid circulation. Then the mechanical response of the porous rock is calculated based on the linear theory of poro-elasticity.

    Morphological updating on the basis of integrated DTMs: study on the Albano and Nemi craters (2008)
    De Gruyter
    Details
    Publication Date: 2021-11-09
    Description: The Colli Albani Volcano has recently developed particular interest in the geophysical community for some peculiar characteristics imputable to a recent residual volcanic activity, thus evidencing that it cannot be considered extinguished yet. On April 2006 an airborne laser scanning (ALS) survey of the Albano and Nemi craters has been carried out to obtain a high resolution digital terrain model (DTM) of the area. We have compared the accuracy of the ALS heights with those obtained by a fast GPS kinematic survey, obtaining maximum deviation within 50 cm. Then, we have integrated the ALS survey of the craters and the bathymetry of the Albano lake to achieve a complete DTM, useful for morphological studies. In addition, with a GNSS/RTK survey (July 2007) we have estimated the Albano and Nemi mean lake levels respectively at 288.16 m and 319.02 m (asl). Based on the integrated DTM and the newly estimated water level values, we have evaluated about 21.7 106 of m3 the water volume loss of the Albano lake from 1993 to 2007, with an average rate of about 1.6 106 m3/yr.
