The Etneo Observatory, the Catania headquarters of the National Institute of Geophysics and Volcanology, has among its primary tasks the seismic and volcanic surveillance of Sicilian volcanoes and seismic areas of eastern Sicily. In order to meet these obligations, it needs to transfer in a safe manner a variegated multitude of data ranging from images coming from thermal cameras to data from GNSS stations. Some types of data, such as those from permanent seismic network, also need to be transferred very quickly in order to implement rapid alert systems (e.g., “seismic early warning”). For this reason, as part of the “Vulcamed” infrastructure project, a microwave data transmission network was designed and built that ranges from southeastern Sicily to the Aeolian islands and Palermo involve five Sicilians provinces (CT, ME SR, EN, PA). This network uses professional radio systems operating in licensed band that guarantee high operating standards and advanced management functions.
