NASA Imaging Triumph March 9, 2014

I am personally not surprised that NASA can tell when sinkholes will appear.  I mean, the stuff they do is just incredible, so why not this?  With plane-based imaging, they can probably tell what I had for breakfast (certainly the NSA can).

In a press release, JPL announced that NASA can tell when sinkholes will develop…after it happens.  Well, not exactly.  Let me explain:

NASA's UAVSAR radar captured precursory ground surface movement of up to 10.2 inches

Analyses by NASA’s C-20A jet Uninhabited Airborne Vehicle Synthetic Aperture Radar (UAVSAR) performed after the Bayou Corne, La., sinkhole formed show it was able to detect precursory ground surface movement of up to 10.2 inches (260 millimeters) more than a month before the sinkhole collapsed in Aug. 2012. This interferogram was formed with images acquired on June 23, 2011 and July 2, 2012. Colors represent surface movement, with one full color wrap corresponding to 4.7 inches (120 millimeters) of displacement. The event in question left a mark:

Louisiana sinkhole

Still I can think of more spectacular imaging:
