We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

Featured Earthquakes Observation Method: Sentinel-1 C-SAR
The Synthetic Aperture Radar (SAR) aboard the ESA (European Space Agency's) Sentinel-1A/B satellites provides continuous all-weather, day-and-night land imagery. SAR images can be combined to produce interferograms, which are images showing changes in land height or position associated with earthquakes.
Join us Jan 25 at 2 p.m., ET [UTC -5], to learn how to use the Alaska Satellite Facility's OpenSARLab to work with synthetic aperture radar (SAR) data in the cloud.
Ground deformation caused by the April 25 Nepal earthquake is clearly visible in this new interferogram processed from Sentinel-1A data by ASF DAAC scientists Franz Meyer and Wenyu Gong.
Explore and download data and imagery from EOSDIS for the the Nepalese region affected by the earthquake on April 25, 2015 and aftershocks.
