We are continuing our Monday to Friday satellite imagery brain teasers to provide a fun distraction for adults and kids alike during these uncertain times. So, what well-known location, feature or landmark on Earth are we looking at today? Check back tomorrow when we will reveal the answer and see if you guessed right! The answer to Day 9's challenge is at the bottom of this page. Ready? Steady? Here we go…
Day 9 answer: The image is a wrapped differential interferogram showing contours of surface deformation associated with the Ridgecrest earthquakes that occurred in California on July 4th and 5th 2019. It was derived through interferometric processing of a pre- and post-event Synthetic Aperture Radar (SAR) image acquired by the Sentinel-1 satellite mission. "InSAR" is a very powerful remote sensing processing technology capable of providing a unique insight into the location, extent, magnitude and temporal evolution of surface deformation.
