Venice, the charming city of canals, will probably drown by three inches over the next 20 years.
Latest measurements reflect the historic Italian city's slow yet progressive sink, even as previous studies certified its stability.
"Venice appears to be continuing to subside, at a rate of about 2 mm a year," said Yehuda Bock, geodesist with Scripps Oceanography Institute, University of California, San Diego, who led the study, reports the journal Geochemistry, Geophysics, Geosystems.
As geodesist, Bock deals with the measurement and representation of the Earth, including its gravitational field, according to a Scripps statement.
Bock worked with colleagues from the University of Miami in Florida and Italy's Tele-Rilevamento Europa, a company that measures ground deformation, to analyse data collected by GPS and space-borne radar (InSAR) instruments regarding Venice and its lagoon.
