Northern Algeria experienced moderate and large earthquakes (with Mw > 6) during the last decades due to the convergence between the African and Eurasian plates. We conduct the joint analysis of multi-temporal SAR-dataset (1995 to 2021), combined wit

Synthetic Aperture Radar (SAR) satellite imagery is a source of data widely employed in the quantification and analysis of an earthquake coseismic displacement. However, due to the signal path along the atmosphere and to other sources, the interferom

In this work, we present a methodology for correcting the major dominating errors in SAR interferograms. Ionospheric effect, orbital and tropospheric errors can lead to a serious damage the interferometric phase, and case a limitation for the retriev

This paper deals with generation of post-seismic velocity and deformation fields of the GNSS network of New Zealand, due to the Kaikoura earthquake (Mw7.8), on November 13th, 2016. The PPP model was performed to estimate daily coordinates, during one

Ionospheric phase delay and orbital errors, are major limitations for precise deformation measurement in low frequencies SAR systems. The dispersive nature of the ionosphere introduces a shift in SAR images that is translated to differential interfer
