“…It is the most sensitive method to detect the conductivity of rock masses and is, therefore, commonly used in the detection studies of seismogenic structures (Unsworth and Bedrosian, 2004;Becken et al, 2011;Zhao et al, 2012;Zhang et al, 2016;Zhan et al, 2017;Wang et al, 2018;Ye et al, 2018;Ye et al, 2020). The results of threedimensional MT exploration in recent years suggest that moderate and strong earthquakes and aftershocks are closely related to the resistivity structure of underground media (Zhao et al, 2012;Zhan et al, 2013;Mohan et al, 2015;Aizawa et al, 2017;Arora et al, 2017;Cai et al, 2017;Sun et al, 2019;Ye et al, 2020;Peng et al, 2022). Some moderate and strong earthquakes have occurred near the boundary between high and low resistivity structure of underground media.…”
