Abstract
Landslides are a major environmental, social, and economic threat to societies. The in-situ monitoring of ground movements provides detailed and high-precision measurements, nevertheless, they are expensive, time-consuming, and not applicable over large areas. Nowadays the satellite InSAR (Interferometric Synthetic Aperture Radar) techniques are a more convenient alternative to detect and characterize geohazards, especially at large scale, by retrieving ground deformation measurements with millimeter accuracy, low cost, and wide coverage. This chapter provides a first-of-its-kind national scale analysis of InSAR data, from the from the recently launched European Ground Motion Service (EGMS), versus landslide susceptibility map of the GeoSure layer of the British Geological Survey. The work also includes an analysis of the theoretical InSAR visibility conditions for Sentinel-1 and the susceptibility map to provide insights on the potential impact of mapping and monitoring landslide data in Great Britain using the EGMS service.
