Detailed structural map of the Min Shan region. (a) A detailed structural map18 over shaded topographic relief. 2017 Jiuzhaigou earthquakes (Hypocenters from the China Earthquake Networks Center; focal mechanism from the USGS) and regional earthquakes during the last century (magnitude ≥ 5; http://service.iris.edu/fdsnws/event/docs/1/builder/) along the Huya fault are shown. The red box shows the location of Fig. 4b. The digital elevation data were downloaded from http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp. (b) Projected Hypocenters in the red box (Fig. 4a) along the main strike of the blue dashed line in Fig. 4a. The red lines are interpreted as the Huya fault; the green lines are strata. The topographic map was prepared using Generic Mapping Tools (GMT) (http://gmt.soest.hawaii.edu/). The map was drafted by X.X. using the CorelDRAW software package (http://www.coreldraw.com/en/product/graphic-design-software/).
