The images were taken before (September 09, 2018) and 36 hours after the hurricane's landfall (September 15, 2018 18:57 PM local time).
UPDATE 9/18/18:The images were taken before (September 09, 2018) and 36 hours after the hurricane's landfall (September 15, 2018 18:57 PM local time).  The ARIA team has created a flood extent map from Sentinel-1 SAR data acquired from Track 106, 36 hours after the landfall of Hurricane Florence. The map was pushed to the FEMA's SFTP server and is available to download from  https://aria-share.jpl.nasa.gov/...

The map shows estimated damage from the 2019 Southern California Earthquakes, with the color variation from yellow to red indicating increasingly more significant surface change, or damage.
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, created this map depicting areas that are likely damaged as a result of the recent major earthquakes in Southern California. The color variation from yellow to red indicates increasingly more significant surface change, or damage. The map covers an area of 155 by 186 miles (250 by 300 kilometers), shown by the large red polygon. Each pixel measures about 33 yards (30 meters) across.

Observed Flooding Areas Using SAR Data after Hurricane Michael
The picture above is a flooding map created by Professor Robert Brackenridge at The University of Colorado. The data to create this map was derived from The European Space Agency (ESA) Copernicus Sentinel-1 satellite. Sentinel-1 is a two satellite constellation with the prime objectives of Land and Ocean monitoring. Sentinel-1A and Sentinel-1B satellites carry the single C-band Synthetic Aperture Radar (SAR) instruments, which can provide an all-weather, day-and-night...

ESA Sentinel-1 Imagery
Acquired Nov. 11. 2017 Acquired Nov, 11 2017 NASA color coded SAR based flood detection maps reveal extensive flooding in areas of Vietnam. The SAR data used in analysis are Copernicus Sentinel data (2017), processed by ESA. In the figures, the blue tones represent flooding due to Typhoon Damrey while the black color represents water covered areas before the typhoon. Other colors indicate mostly land...

SARs image of the Oaxaca Mexico Earthquake.
Rewrapped Sentinel-1 Interferogram for the M7.2 Pinotepa de Don Luis, Mexico earthquake from Feb 16, 2018.  Ascending Sentinel-1 SAR interferogram rewrapped to 10cm color contours of line-of-sight surface deformation. The frame was processed automatically by the UAF SARVIEWS processing service (http://sarviews-hazards.alaska.edu/). Sentinel-1 data from 02/05/18 and 02/17/18 was used. Contains modified Copernicus Sentinel data [2018]. Data accessed through the Alaska Satellite Facility....
