Tenerife Island Ddeformation Analysis in the 2003-2006 Period Employing the Coherent Pixel Technique and ENVISAT SAR Images

Geodetic measurements in volcanic areas are crucial as they serve as input information to the deformation analysis techniques in order to achieve pre-eruption ground displacement predictions. We present ground motion results obtained by applying the Coherent Pixel Technique, an Advanced Differential SAR Interferometry algorithm, which reveal surface deformation episodes in the Tenerife Island. The study is carried out by employing DInSAR interferograms concerning the 2003-2006 period corresponding to both ascending and descending images acquired by the ENVISAT ASAR sensor. The obtained results highlight a clear deformation areas in several parts of the island Tenerife, which is consistent with previous results.
