They found that the luxury building is tilting. Not only that, but it's sinking, too! As of completion, the building is tilted two inches to the northwest, and sunk 16 inches. There's a bunch of reasons why this "Leaning Tower of San Francisco" is creating a lot of problem in The City by the Bay.
The way they measured the sinking situation wasn't from the ground, but with the help of the European Space Agency. They used Copernicus Sentinel-1 twin satellites to scan the area down to the millimeter for any slight changes.
The Sentinel-1 satellites showed that the Millennium was sinking by around 40 millimeters a year by the direction that they were looking at the building. The image above has colored dots representing spots observed by the radar. Green means a stable target; the red ones on or around the Millennium Tower mean that they've moved.
Millenium Partners, the developers of the building, blame the construction of a new transportation station nearby. The Transbay Transit Center started construction two years after the Millennium Tower was completed. There are a lot of serious allegations being thrown around.
Even with all the work being done on the Leaning Tower of San Francisco, there's nothing more unnerving that to have your high-end car next to a cracked wall with stress gauges. It's worrying when you put down a ball on your nice floor and it rolls to one side for no reason.
The residents are still not happy with what's happening. "The real issue for me is that it hasn't slowed down," said one tenant. Many residents think the partners should have told them about the sinking and tilting earlier. They only told them six years after it was completed and, of course, most were sold by then.
