The complex karst dynamics of the Lisan Peninsula revealed by 25Â years of DInSAR observations. Dead Sea, Jordan

This article presents and analyses the results obtained from Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques applied to ERS-1/2, ENVISAT, ALOS-PALSAR, COSMO-SkyMed, and Sentinel-1A datasets over the Lisan Peninsula, located in the southern part of the Dead Sea, Jordan. The novelty comes from the integration of three different wavelengths to study the dynamics of a salt dome. The monitoring activity entirely covers the period extending from 1992 to 2016. Five displacement maps have been produced, carefully checked and then fused to provide a total cumulated map of the displacements in the area. The ground movements have been analysed by comparison with in-situ tectonic observations collected by various authors since the mid-1980s. The study shows an episodic rising of the Lisan diapir. The presented results can be useful to update the knowledge of the displacement rates occurring in the area and to better comprehend the complex dynamics of the Lisan Peninsula.
