June 30 (UPI) -- A preliminary satellite assessment by the National Aeronautics and Space Administration estimated that 58,870 buildings were damaged or destroyed after the twin earthquakes that struck Venezuela on June 24, as the death toll climbed above 1,700. The assessment offers one of the clearest pictures yet of the scale of the disaster. The analysis was produced using radar data from the Sentinel-1 satellite, part of the European Union's Copernicus Earth observation program. By
