Most previous studies have indicated that the ground subsidence has stabilized under the famous City of Venice, Italy. However a recent study published in March indicates this may not be the case. The researchers used GPS and InSAR data from 2000 to 2010 and found the rate of subsidence on the order of 1 – 4 mm per year. [Source: CBS News via Geology.com. Image: Wikipedia/Saffron Blaze]
