Earthquake distribution and sketches of the deep structure of the Min Shan and Longmen Shan regions. (a) Regional earthquakes during the last century (magnitude ≥ 5; http://service.iris.edu/fdsnws/event/docs/1/builder/). The Wenchuan earthquake3 and the Songpan-Pingwu earthquake18 are labelled. (b) The crustal structure of the Min Shan and the Bikou block. (c) The crustal structure of the Longmen Shan and the Sichuan basin10. The digital elevation data were downloaded from http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp. 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/).
