The validity of magnetotelluric time-series processing methods has been lacking reasonable testing criteria. Since the time series synthesized by existing techniques are not fully derived from a given model, they reliable. In this paper, we present novel approach to synthesize based on forward modeling and correspondence between frequency domain electromagnetic fields. approach, obtain response...

Generally, the water-bearing structures of coal mines mainly include seam, roof, floor, and goaf, while main water-conducting faults, collapsed columns, goaf areas. The most commonly used methods for detection above seismic method, high-density electrical controlled source audio-frequency magnetotelluric transient electromagnetic method. Theoretically, have a higher resolution, which can be to ...

Following the electric current injection experiment carried out in 2009, a VLF-MT (Very Low Frequency Magnetotelluric) survey has been conducted in Kozu-shima Island to obtain further information on the subterranean electrical structure that might help understanding the results of our monitoring of geoelectric potentials. A number of VAN-type pre-seismic geoelectric potential anomalies were obs...
