- Description
Radar satellite missions can measure millimetre-scale changes in Earth’s surface following an earthquake. On 24 August 2014, an earthquake struck California’s Napa Valley. By processing two images from the Sentinel-1A radar satellite, which were acquired on 7 August and 31 August 2014 over this wine-producing region, an 'interferogram' was generated showing ground deformation.
