Spotting geohazards with Sentinel-1

The Geohazards Exploitation Platform gives users direct access to large Earth-observation datasets for areas at risk of geohazards such as earthquakes and volcanic activity. Pairs of Sentinel-1A radar images from consecutive passes over the same spot on Earth’s service are processed continuously and automatically to provide medium-resolution (200 m) images. This, and related interferograms, allows users to identify ground movement and other changes that may have occurred between satellite acquisitions. The service currently covers tectonic areas in Europe. Covering three million square km, this represents 360 interferometric pairs every 12 days.
