Satellite radar interferometry is a well‐documented technique for the characterization of ground motions over large spatial areas. However, the measurement density is often constrained by the land use, with best results obtained over urban and semi urban areas. We use an implementation of the Small Baseline Subset (SBAS) methodology, whereby areas exhibiting intermittent coherence are considered alongside those displaying full coherence, in the final result, to characterize the ground motion over the South Wales Coalfield, United Kingdom. 55 ERS‐1/2 Synthetic Aperture Radar (SAR) C‐band images for the period between 1992 and 1999 are processed using the ISBAS (Intermittent Small BAseline Subset) technique, which provides 3.4 times more targets, with associated measurements than a standard SBAS implementation.
