Abstract


In this work, the vertical displacement of the low-Nekor basin surface caused by the MW 6.4 Alboran Sea earthquake of 25 January 2016 is presented. This study has been carried out based on free satellite radar images acquired by Sentinel1 in SLC mode (Single Look Complex). The processing steps have been achieved using the open source software SNAP (Sentinel Application Platform), also provided by the European Space Agency (ESA). The deformation maps are obtained by the two pass DInSAR (Differential Interferometric Synthetic Aperture Radar) of two image pairs, where the slave was acquired on 02 February 2016, and the masters on 28 December 2015 and 21 January 2016. The result of DInSAR technique shows that an uplift phenomenon has occurred in the study area (maximum amplitude of 2.8 cm).
