| Abstract | Modern geodetic measures provide information on surface deformation at high accuracy. Using radar remote sensing techniques, we image an uplift of several centimeters over a square kilometer area around the geothermal power plant of Landau (Germany). The surface deformation affects a large part of the city. The persistent scatterers interferometry (PSI) processing of the synthetic aperture radar (SAR) images shows that the displacement initiates in the summer 2013 and increased during the whole production time, until March 2014. Results from modeling suggest that a significant injection of fluid occurred around 400 meters depth below the geothermal plant during the first phase of deformation. |
