Uninterpreted (top) and interpreted (bottom) seismic profiles (2D data) across ST9 well in the northern Longmen Shan area, showing the characteristics of thrust sheets, tectonic wedges, and foredeep. The vertical axis is in meters. The earthquake data are from the database of USGS (https://earthquake.usgs.gov/). The location of this seismic line can be found in Figure 1(d). The full names of abbreviations of the strata can be found in Figure 2. Courtesy of the Southwest Oil and Gas Field Company, PetroChina for the seismic and surface geological data.
