Active tectonics in Quaternary marine formations in the Tangier region (North West Rif, Morocco): Persistent Scatterer (PSInSAR) contribution

Abstract

This study investigates recent tectonic activity in Tangier, Morocco, using PSInSAR data and microtectonic field observations. The exploration of marine deposits in the Achakar basin during the Plio-Quaternary period holds significance for tracking the recent geodynamic changes in the study area. Microtectonic analysis revealed a shift from a NE-SW compressive regime in the Late Pliocene to a Quaternary regime dominated by a NE-SW extension regime and a NW-SE compressive regime. PSInSAR detected ground displacement rates ranging from subsidence (-4.9 mm/yr) to uplift (4.9 mm/yr) during the study period (2018 2021).
