AbstractObservations of seismic, hydrologic or fumarolic activity have proven useful as reliable eruption precursors. In the last years, geodetic measurements are being used more extensively in active volcanoes because they have been shown to provide a reliable eruption precursor. Furthermore, ground deformation measurement techniques are attracting more attention, in particular with regard to pre-eruption ground displacement. The introduction of new geodetic techniques such as Global Positioning System (GPS) and Synthetic Aperture Radar Interferometry (SAR) can be highly useful in this context, because both techniques have pro ven to be a suitable tool for ground deformation monitoring of active volcanic areas. In this frame, it is possible to demonstrate the feas ibility of using space technologies for operational decision support demonstration at a volcanic risk scenario like Canary Islands. Particularly, the good existing coherence of volcanic areas makes them very proper for InSAR techniques application. By other hand, the theoretical and observational results of the analysis of sensibility of existing classical networks have made necessary the designing and observation of a GPS network in the island of Tenerife with a global coverage and monitoring purposes. This GPS network would be a complement and checking of InSAR observations performed in the island. The main objective of this job is defining and checking the applicability of a new geodetic monitoring system in Tenerife. In order to gel this, we make use of the existing facilities in the island and the new geodetic space techniques. We try to gel the possibility of detection of deformation at any part of the island. Therefore, the new system must be able to allow us the monitoring of any existing ground movement in the island.
