General
The city of Staufen im Breisgau lies in the Land district of Breisgau-Hochschwarzwald (Breisgau-Upper Black Forest) in the German State of Baden-Württemberg. The City of Staufen has approximately 7700 inhabitants and forms, together with the community of Münstertal, a community administrative unit.[1]
It is noted in history and culture for its association with Dr Faustus who, according to legend, sold his soul to the Devil at an inn here.
Geography
Staufen lies at the foot of the Black Forest at the exit from the Münstertal. The Black Forest valley of Neumagen goes here directly over into the Rhine plain. The piedmont of the Black Forest is less distinct. North of the valley exit, the steeply rising Schlossberg dominates; to the southwest begins the hilly landscape of the Markgräflerland. Staufen lies on the border between two natural and economic areas: the Rhine plain up to the piedmont with its cultivation of grain, winegrapes and vegetables; and the Black Forest, with its cattle and forestries, and, in an earlier time, mining.[1]
Geothermal drilling controversy
Since 2008, the center of the city has been reported to have been rising some 12 cm so far,[2] after initially sinking a few millimeters.[3] This has been causing considerable damage to buildings in the city center, including the historical town hall. One hypothesis for the cause of this geological change is a drilling operation conducted in the fall of 2007 to provide geothermal heating to the city hall. The drilling perforated a gypsum layer and caused high-pressure groundwater to come into contact with the gypsum, which then began to expand. Currently no end to the rising process is in sight.
Data from the TerraSAR-X radar satellite before and after the changes has confirmed the localised nature of the situation. "A geochemical process called anhydrite swelling has been confirmed as the cause of these uplifts. This is a transformation of the mineral anhydrite (anhydrous calcium sulphate) into gypsum (hydrous calcium sulphate). A pre-condition for this transformation is that the anhydrite is in contact with water, which is then stored in its crystalline structure."[4]
