We have processed data from the Copernicus Sentinel-1 satellite, covering the period from January 2021 to September 2023, over the borader area (around 48400 square kilometers) of Oran, Algeria. This analysis utilized the SNAPPING Persistent Scatterers Interferometry (PSI) service from the Geohazards Exploitation Platform (GEP; accessible at geohazards-tep.eu). Processing was performed by the EO.Lab of AUTh.  Measurements contain average Line-of-Sight (LoS) velocities, corresponding uncertainties, and the complete displacement time series. The dataset contains ~3M points covering approximately 7800 sq.km (density of 385 points/km).  References [1] Foumelis, M.; Delgado Blasco, J.M.; Brito, F.; Pacini, F.; Papageorgiou, E.; Pishehvar, P.; Bally, P.
