With growing involvement in disaster and risk management, NPA are at the forefront in the application of satellite SAR Interferometry (InSAR) for ground displacement and subsidence detection.

With growing involvement in disaster and risk management, NPA are
at the forefront in the application of satellite SAR Interferometry
(InSAR) for ground displacement and subsidence detection. Stage 1 of
Terrafirma, the Pan-European Ground Motion Information Service of the
ESA GMES Service Element Programme, is now complete under NPA’s lead.
Initially the service focuses on urban subsidence but will include
earthquake zones, landslides, coastlines and flood plains, in support
of policies aimed at saving lives, improving safety and reducing
economic loss. The project utilises PSI (Persistent Scatterer
Interferometry) to detect millimetric ground motion displacements from
multiple radar scenes. NPA Chairman Nigel Press together with Dr.Chris
Browitt, seismologist with British Geological Survey, were interviewed
live on BBC Radio 4‘s Material World programme featuring InSAR and
Terrafirma. To hear the March 10th broadcast via web go to BBC Listen
