Geophysical processes and anthropogenic activities cause the deformation of the Earth's surface,both mechanisms interacting sometimes simultaneously. While the occurrence of thoseprocesses in rural areas may not always directly a ect the population, the determinationof surface deformation in inhabited areas is of high relevance to prevent risks. Traditionalsurveying techniques provide exact but usually spatially and temporally limited deformationinformation, making a regular monitoring of whole urban areas di cult. Since about 20 years,RADAR remote sensing, especially SAR interferometry, provide dense and accurate groundmotion information, completing hereby the traditional monitoring techniques. This presentstudy investigates ground surface dynamics in a town close to a former potash-mine situatedin the northern part of Thuringia, Germany, by means of multi-temporal SAR interferometry.Using the method of Persistent Scatterer Interferometry, 20 years of RADAR data from multiplesensors are evaluated and compared to in-situ data. It shows that ground subsidencesdecreased since the closing and back lling of the mine, which is in accordance with surveyingactivities on this site.
