The map was derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency (ESA). The team compared the post-event image acquired on January 14, 2020 with pre-event images taken since September 2019. The color variation from yellow to red indicates increasingly more significant surface change.</span></p><p><span>Preliminary validation was done by comparing with anecdotal reports on news media. This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated areas. For example, the scattered colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage. Small scale change or partial structural damage may not be detected by this map. </span></p><p><span style='font-weight:bold;'>Suggested Use: </span></p><p><span>This damage proxy map shows surface change with yellow to red indiciating more significant change or building damage due to the recent earthquakes.
