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....
