Assessment of the Risk of Landslides and Rockslides in Northern Morocco by Radar Interferometry Differential

The northern Rif is probably the region of Morocco the most affected by various types of natural hazards. Landslides and rock slides are widespread, mainly due to geological causes, such as the nature of facies, tectonics, climatic conditions, and urban planning activities in the region. These risks have been monitored using the DINSAR technique (Differential Radar Interferometry), which gives an accurate estimate of soil deformation rates typically from a few millimeters to a few centimeters over large areas. The DINSAR treatment method is performed using SNAP software, then the image-generated NDTs from the Sentinel 1A, 1B satellites are a family of Earth observation satellites launched respectively in April 2014, April 2016.
