More than 150 ERS images acquired between 1992 and 2000 were combined by the British Geological Survey to produce this InSAR-based depiction of crustal movement around Hamamatsu-Yaizu on Japan's south coast. It measures the annual average line of sight velocity in millimetres per year of 'permanent scatterer' fixed points. Light blue indicates 1 to 3 mm, green 1 to -1 mm, yellow -1 to -3 mm, orange -3 to -5 mm, and red greater than -5 mm. Applications of the data include geological risk assessment for the insurance industry and exploring links between ground movement and gas pipe failure.
