Generation of Added Values Products Supporting Risk Analysis

Active volcanoes are spread all over the world and are located in specific areas correlated to geologic structures. In the last 10,000 years more than 1300 volcanoes have erupted, but only half of the eruptions have been reported in historical texts. It has been estimated that every year 50 volcanic eruption may occur threating about 10 % of the worldwide population. Considering the constant increase in human population and that many major cities are placed in the proximity of active volcanoes, the number of people subjected to the risks caused by volcanic eruptions is also increasing. Stated the problem dimension, it shall be defined the method to counter act the crisis scenario. A volcanic eruption can be faced under different point of view, on one side it can be deeply studied in order to improve the knowledge of geophysical mechanism which drives the eruption itself, on the other hand it is important to set up a service based on the integration of different dataset and aimed to deliver added values products toward whose are in charge to manage the risk associated. One response to last sentence is the Sistema Rischio Vulcanico (ASI-SRV) project funded by the Italian Space Agency (ASI) in the frame of the National Space Plan 2003-2005 under the Earth Observations section for natural risks management. The ASI-SRV Project is coordinated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) which is responsible, in Iyaly, at national level for the volcanic monitoring. The main goal of the ASISRV project is to define, develop and demonstrate tools and products, based on the integration Earth Observation data (EO) with data coming from the ground monitoring network developed at national and local level, to support the risk management decision procedures. The project philosophy is to implement, by incremental versions, specific modules which allow to process, store and visualize through a dedicated Web-GIS tools, added value information derived by EO and No EO data.
