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 March 08, 2020 with pre-event images taken since August 2019. </SPAN></P><P><SPAN>The color variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done by comparing with the aerial photos by NOAA. 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. This map is most sensitive to building damage, but 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. The damage proxy map should be used as guidance to identify damaged areas and may be less reliable over vegetated areas. The lack of colored pixels over vegeated 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;">Satellite/Sensor:</SPAN></P><P><SPAN>Copernicus Sentinel-1 Synthetic Aperture Radar (SAR)</SPAN></P><P><SPAN>Resolution:</SPAN></P><P><SPAN>30 meters</SPAN></P><P><SPAN STYLE="font-weight:bold;">Credits:</SPAN></P><P><SPAN>Contains modified Copernicus Sentinel data (2020), processed by ESA.
