3 Italian 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.

4 The Italian Volcanic Monitoring System

5 Italy 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 activity The 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

8 INGV 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 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 Istituto Nazionale di Geofisica e Vulcanologia

13 Monitor Ground Networks in Neapolitan Area

14 Ground properties derived developing original remote sensing algorithm: Lava flow effusion rate Reflectance, Emissivity, Ground temperature DTM Ground deformation by InSAR techniques Volcanic plumes parameters derived developing original remote sensing algorithm: - SO2 content and flux in volcanic plumes - Water content in volcanic plumes - Optical depth - CO2 content in volcanic plumes Periodic Filed Campaign to Validate algorithm retrievals EXTRACT THE INFORMATION/PARAMETER FROM REMOTE SENSED DATA

15 Satellite monitoring facilities - The 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.

18 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.http://srv1.rm.ingv.it/srv/srv SISTEMA RICHIO VULCANICO (SRV)

21 Page 21 System Concept The Volcano Monitoring System will be made of the following elements: –Ground Network, dedicated to collect primary information from volcanoes with Seismic and GPS systems –Multi-Satellite Reception Centre, devoted to enrich Ground Network information with processing chain for deriving specific products from optical and radar (SAR) data –Regional Analysis Platform, representing the centre where both Ground Network and Optical and Radar (SAR) data are analysed and integrated for deriving specific information on monitoring –Local 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 Makers –Satellite 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 result –It is expected one (or two) multi-satellite reception centre, a regional analysis platform for each country and several local delivery platform.

26 Page 26 The Ground Network will be designed depending from the local existing infrastructures and need in order to optimize the data integration with satellite measurements Seismic and GPS systems will represent the prime infrastructure Acoustic instruments could also be used. Correlating infrasonic and seismic events provides better eruption detection that ground system will detect and trigger the spatial acquisition systems GROUND NETWORK (MAINLY Seismic and GPS) GROUND NETWORK

27 Page 27 The Satellite Link System will be designed in order to support broadcasting of the information from the Ground Network to the Regional Analysis Platform and Local Delivery Platform. The Satellite Link System will consist of a telecommunication satellite broadband that will allow the distribution of any data using fixed and mobile stations. The architecture will be based on a Network Operation Centre with a master antenna and remote terminals. This network will allow the customer to have a complete broadband infrastructure that could be used to disseminate either Ground Network data (such as IP Multicast Internet Access, Web applications IP, Private Networks Sensor and network monitoring, Terrestrial Backup e disaster recovery, VoIP Video communications, Telemedicine and e-learning).
