This image is the disturbing one: https://twitter.com/ctdonath/status/1285027190350983169?s=20
As I noted above, the power lines are clear and straight. The dam isn’t.
I’m going to take the other side on this one. I tried putting the side of a piece of paper against the power lines next to the biggest deformity and in fact they don’t seem straight. And since they are at an almost 90 degree angle to the direction of the deformity, I would expect them to be only very slightly deformed by warping the dam perpendicular to its run. I also find it a bit suspicious that the greatest deformity occurs in a place where there’s no power lines.
Also, I think that if structures that large shift even a half inch, which you would never even notice without a laser measure, they would be severely structurally unsound. This photo suggests tens of feet of deformation.
Maybe it’s possible but I’m pretty doubtful.
Time to close the US Consulate in Wuhan....
