I think I read that the chinese blew up a couple dikes or small dams to relieve pressure on 3GD, and they also lowered the water level to relieve pressure so the dam wouldn’t break. Hundreds of thousands evacuated, if not millions...China controls the news so no one knows.
If3GD collapse, which is a real possibility, they could see it on google earth.
That said, it won't show up on Goggle Maps/Earth until they update their terrain photos.
In fact, satellite photos won't be necessary. The houses and bodies of Chinese washing up on the shores of Nagasaki and Okinawa will be a dead giveaway.

Yes I think they did do some controlled demolition not of dams but of dykes to go ahead and flood farmland so as to take pressure off the TGD.
