  1. We have a similar problem in Lüneburg, a town near Hamburg. The cause is/was extraction of salt from below the city by washing it out with salt brine (Lüneburg has a 1000 years-old history of salt extraction). Subsidence has largely stopped since extraction has been reduced in the 1980ies but some hot spots still subside, likely driven by rain water.
