How satellite radar can detect slight surface movements on Earth

Phlegraean Fields monitored by Sentinel-1 (Image: ESA)

Earth’s changing surface can be closely monitored thanks to the use of satellite radar data. This week at the Fringe Workshop held by the European Space Agency ESA, new advances in the science and applications of Interferometric Synthetic Aperture Radar (InSAR) were presented.

Ground instability in Mexico City showed by satellite radar images

Radar satellites images showing Mexico City subsidence

Five radar scans from ESA's Sentinel-1A have been been combined to create an image showing ground deformation in Mexico City. The image demonstrates that some areas of the city are subsiding at up to 2.5 cm/month.
