AbstractAn unstable rock slope situated between Port-Daniel and Chandler in the Gaspé Peninsula (Quebec) has been impacting a railway line for several decades. As part of a recently developed near real-time monitoring program, the remote sensing technique PTA-InSAR has been applied to monitor the displacement of the rock slope. Deployment of InSAR artificial targets is described, as well as preliminary results from over one year of measurements.
