    Description: Envisat MERIS and AATSR data have been acquired in the framework of the Eurorisk-Preview project. The project addresses European civil protections and proposes to develop, at the European scale, new information services to support the risk management. In Italy one of the most important natural risks is due to the presence of volcanoes. Mt. Etna in Sicily, displays persistent activity, periodically interrupted by eruptions, which emit volcanic aerosol and ash to different altitudes in troposphere affecting the central Mediterranean area. In order to test the use of MERIS and AATSR data to derive emitted particles parameters as optical depth, effective radius and the ash mass of particles, the already developed remote sensing techniques has been adapted. MERIS and AATSR data acquired during the Mt. Etna 2002-2003 volcanic eruption has been chosen. The use of VIS and TIR bands of the two sensor demonstrates the potential to derive useful information on plume particles and to monitor the volcanic plume during eruption if frequent and high resolution data is available in near real time.

    Description: In the framework of the Eurorisk-Preview project, funded by the European Union, a task is dedicated to the assessment, prevention and management of volcanic risk. We are developing a multidisciplinary approach, integrating the geophysical prospecting at local scale and large scale remote sensing data. To achieve this task, two volcanic test sites have been identified: Mt. Etna, in Sicily (Italy), and Tenerife, in Canary Islands (Spain). We investigate the surface deformation and the volcanic emission in the atmosphere by using SAR series and multispectral data, requested in the ESA Category 1 (n. 3560). For Mt. Etna data from historical to recent eruptions (1992 – 2006) has been analysed while for Tenerife archived SAR data from 1992 to 2005 has been analysed, individuating anomaly ground deformations in Pico de Teide and surrounding areas as suggested by GPS campaigns.
