3Italian Seismic and Volcanic Surveillance Italy presents high seismicity on its territory.Active volcanoes are located mainly in the southern regions.The seismometric network has been developed over the last 20 years.Volcanic observatories are active in Napoli and Catania since the presence of Vesuvio-Campi Flegrei and Mt. Etna.
5Italy is subject to different Geohazards risks as earthquakes and volcanoes, moreover the high population density requires a constant surveilance of the volcanoes activiy level.The permanent monitoring of active volcanic areas involve the surveilance many different phenomena related to volcanic activityThe surveilance system must be efficient on detect the signs of an impending eruption and therefore activate the Civil Protection structures.The basic requirements are well organized ground based networks that provide continuous data to observatories and operative centres.Satellite system may improve the monitoring capability by providing new information and a global view of the territory

7Type of volcanic activity produced by the Italian volcanoes Lava Flows (Etna, Stromboli, Vesuvio)Ash Clouds, Strombolian activity (Etna, Stromboli, Vesuvio, Vulcano)Anomalous gas emissions (Panarea, Colli Albani, Vulcano)Lahars, land slides, debris-flows (tutti i vulcani)Tsunami (Stromboli, Etna, Vesuvio)Pyroclastic Flows (Vesuvio, Vulcano, Campi Flegrei)Caldera Collaps (Campi Fregrei, Vesuvio, Etna)
8Istituto Nazionale di Geofisica e Vulcanologia The INGV (Istituto Nazionale di Geofisica e Vulcanologia)is one of the major European research institutes in geophysics. It has many centres and 500 researchers working on seismology, volcanology, geodesy, remote sensing, geochemistry, atmospheric physics.INGV develops and controls many instrumental networks to monitor seismic and volcanic activity with a 24h surveillance of the Italian territory for the Civil Protection

15Satellite monitoring facilities 27 mars 2017Satellite monitoring facilitiesThe INGV Remote Sensing Group has 15 years of experience in the application of SAR Interferometry techniques (authors of the first studies in Italy in 1997) to earthquakes studies and volcanoes monitoring.INGV RS Group develops algorithms to extract volcanic parameters from Optical data to monitor temperature, gas emissions and ash clouds.The INGV RS Group has a wide experience in SAR data time series generation in volcanic areas from different processing techniques.The PSI (Permanent Scatterers Interferometry), the IPTA (Interferometric Point Target Analysis), Small Baselines Subsets (SBAS) and StaMPS (Stanford Method for Persistent Scatters) techniques are currently available at INGV RS Group.INGV RS Group has also experienced the project and development of corner reflectors to be installed in volcanic areas to be reference points for SAR Interferometry products.The INGV RS Group is author of recent studies over the Colli Albani and Etna volcanoes showing the slow deformation of the caldera.15

18SISTEMA RICHIO VULCANICO (SRV) INGV has a gained experience in monitoring of volcanoes with an integrated approach employing both Remote Sensing and Ground data.The Project SRV(Sistema Rischio Vulcanico funded by ASI (the Italian Space Agency), is an example of such a system, developed according to the Italian DPC (Civil Protection Department) requirements, using COSMO-SkyMed data provided by ASI and downloaded through dedicated receiving antennas, under specific agreement.

21System ConceptThe Volcano Monitoring System will be made of the following elements:Ground Network, dedicated to collect primary information from volcanoes with Seismic and GPS systemsMulti-Satellite Reception Centre, devoted to enrich Ground Network information with processing chain for deriving specific products from optical and radar (SAR) dataRegional Analysis Platform, representing the centre where both Ground Network and Optical and Radar (SAR) data are analysed and integrated for deriving specific information on monitoringLocal Delivery Platform, representing the part of the system deployed near the Volcanological observatory where the information is interpreted and make available to Local Authorities and Decision MakersSatellite Link System, represent the framework for broadcasting the information especially from the Ground Network to the Regional Analysis Platform and Local Delivery Platform via satellite telecommunications. The use of this network to other communications needs within the system will be evaluated during the feasibility study activities.The deployment of these elements depends on the feasibility study resultIt is expected one (or two) multi-satellite reception centre, a regional analysis platform for each country and several local delivery platform.
