Sentinel-1 Likelihood of Damage for the Venezuela Earthquake
NASA's GIS portal displays Sentinel-1 satellite data showing the likelihood of damage from the Venezuela earthquake, using a map viewer to depict areas potentially affected by the seismic event.
Background
- This is an interactive NASA map showing damage likelihood from a Venezuela earthquake, based on data from Sentinel-1, a European satellite constellation operated by the Copernicus Programme. Sentinel-1 uses Synthetic Aperture Radar (SAR) to detect ground deformation before and after an earthquake.
- The map uses a color scale (green to red) to indicate the probability of building or infrastructure damage. It is a rapid assessment tool used by disaster response teams, not a final damage survey.
- Earthdata is NASA's platform for Earth science data; this map comes from the NASA Disasters Program, which provides satellite-derived information to aid emergency management during natural disasters.
