“…GPS surveys represent a key tool to investigate geodynamic processes at the Earth's surface and estimate volcanic and seismic strain in active areas, such as along faults or signals from magmatic injections at surface, occurring inside volcanic reservoirs [Dvorak and Dzurisin 1997, Anzidei et al 1998, Anzidei et al 2001, Serpelloni et al 2005, Serpelloni et al 2006, Anzidei et al 2008, Tregoning and Rizos 2008, Esposito et al 2010, Patanè et al 2013, De Martino et al 2014, Ferranti et at. 2014, Baldi et al 2015. Surveys style GPS networks set up in Italy during the last decades, now have a crucial role to densify the current CGPS networks, thus better constraining the velocity field solutions and related strain maps, especially during seismic cycle and hydrothermal volcanic systems [Anzidei et al 2009.…”

<p>Since the early 1970s, geodetic networks became a most important tool to monitor the present day deformations of the volcanic arc of the Aeolian Islands. The first benchmarks were installed in this region at Lipari and Vulcano Islands and the number of GPS benchmarks increased in time since the early ’90s. These networks were periodically surveyed in the frame of national and international geodynamic projects and for Civil Protection programs devoted to the mitigation of the volcanic hazard. The Istituto Nazionale di Geofisica e Vulcanologia (INGV) played a fundamental role in the realization and periodical reoccupation of these networks, with the goal to investigate the tectonic and volcanic processes, still active in this crucial area of the central Mediterranean. An updated GPS velocity map for this region, both for the horizontal and vertical component of land motion, with details for Lipari, Vulcano and Panarea Islands, is provided in this paper. The presented GPS velocity field also includes a set of additional discrete stations located in northern Sicily and Calabria together with data from the available CGPS networks active in southern Italy. Here we show the results from eighteen years of repeated GPS surveys performed in this region in the time span 1995-2013 and the open access AINET-GPS data archive, now freely available for the scientific community. Data will support scientific research and hopefully improve the assessment of volcanic and seismic hazard in this region.</p>
