Three dimensional velocity structure and accurate earthquake location in Changning–Gongxian area of southeast Sichuan. Earth Planet. Phys., 4(2), 163–177. doi: 10.26464/epp2020022 |
In order to understand the crustal structure and tectonic background of the Changning–Gongxiang area, southeastern Sichuan Province, where a series of moderate-to-strong earthquakes occurred in recent years, we utilized the seismic phase data both from a local dense array and from the regional seismic networks; we used the tomoDD program to invert for the high-resolution three-dimensional velocity structure within the depth range of 0–10 km and for accurate hypocentral locations in this area. We analyzed the seismogenic structures for the events of Xingwen
