我们提出了一个大规模的电阻率实验成像断层系统的深度为几百米。一个强大的发射机和连续登记的电位差是用来获取时间序列的配置文件超过2公里的长度。在频域中处理时间序列以获得约300个视在相干度。一个独立的反演揭示了故障线的过程，但显示了平滑的电阻率分布。通过将结构信息添加到反问题中，来自反射勘测的地震数据能够显著地改善电阻率图像。
We present a large-scale resistivity experiment to image a fault system down to a depth of a few hundred meters. A strong transmitter and continuous registration of potential differences is used to acquire time series on a profile of more than 2,km length. The time series' are processed in frequency domain to obtain about 300 apparent resistivities. An independent inversion reveals the course of the fault line but shows a smoothed resistivity distribution. Seismic data from a reflection survey are able to significantly improve the resistivity image by adding structural information to the inverse problem.
