英文摘要	The 2017 Wulong earthquake (Ms 5.0) took place in Chongqing, China, causing serious damage to the local infrastructure. However, the mechanism of this earthquake is still unclear. We deployed a 155 km long magnetotelluric (MT) profile with 24 broadband sounding stations across the Wulong earthquake zone. The phase tensor and phase-out-of-quadrant data analysis show that the whole region is mainly characterized with 3-D electrical resistivity structure. High-quality full electrical resistivity impedances were inverted by a 3-D scheme to image the structure beneath the profile. The 3-D electrical resistivity model indicates that the dynamic environment of the central and eastern Chongqing and the Two Lakes plains is different from the neighboring areas. The different stress environment of the study area observed suggests that this area is prone to earthquakes. The Wulong earthquake (Ms 5.0) may have been generated by the local stress adjustment of the Qiyaoshan basement fault. © 2021 Elsevier B.V.
