Summary:
We investigate an active fault by using radiomagnetotelluric (RMT) and direct current resistivity (DCR) method. RMT and DCR field data set observed across an active fault located close to the city of Kerpen in Germany. First, the synthetic RMT and DCR data is generated for similar model expected from the investigated field geology. The individual and 2D joint inversion results of these data sets were compared and we demonstrated that the 2D joint inversion result based on this synthetic data simulates the real model more accurately than the 2D inversion results of each individual method. Then, the field RMT and DCR data are inverted individually and jointly and showed that 2D joint inversion of two data sets are better shows fault location and depth from the surface then the individual data set inversion.
