Investigating ground movement and its causes in London, UK, using SAR Interferometry
Started: October 2014
Description of Research
This research aims to improve understanding of ground movement and its causes in London. The model of London's geology has been changing rapidly over the past 5 years and it is now thought that the London Basin is underlain by a series of rigid blocks, tens of kilometres in scale, that are moving on a millimetre scale relative to one another. The project aims to monitor and improve understanding of these small-scale movements using Differential Interferometry based on Synthetic Aperture Radar images (DInSAR). The outcomes of this project will be particularly important for urban subsurface designs, for which mm-scale ground movement, if unanticipated, can incur major costs and safety risks.
