Crustal fluids exist near fault zones, but their relation to the processes that generate earthquakes, including slow-slip events, is unclear. Fault-zone fluids are characterized by low electrical resistivity. Here we investigate the time-dependent crustal resistivity in the rupture area of the 1999 Mw 7.6 Izmit earthquake using electromagnetic data acquired at four sites before and after the ea...
Mine water is a menace to coal mining. Transient Electromagnetic Method (TEM) is a relatively quick and efficient method to detect the water yield property of a targeted layer. Based on mine-oriented 3D TEM observing system, the signal of induced voltage is obtained. TEM 3D data volume can be calculated through the calculation of late-period resistivity and time-depth conversion. After setting ...
