Scientist Petar Marinkovic who analyzed the data for the ESA said Monday it shows the Millennium Tower sunk 40 to 45 millimeters — or 1.6 to 1.8 inches — over a recent one-year period.

It sunk almost double that amount — 70 to 75 mm (2.6 to 2.9 inches) — over its 17-month observation period ending in September, he says.

The luxury high-rise has sunk about 16 inches and is also tilting. Engineers have estimated the building is still sinking at a rate of about 1-inch per year.
