The 20 April 2013 Mw 6.6 Lushan earthquake occurred at the geologic boundary between the western Sichuan basin and the eastern flank of the Tibetan plateau. This earthquake occurred 100 km south‐southwest of the epicenter of the 2008 Mw 7.9 Wenchuan earthquake (Fig. 1). In response to the deadly Wenchuan earthquake, there has been a significant increase in the density of seismographic, strong‐motion, and Global Positioning System (GPS) stations throughout western Sichuan Province, including the vicinity of the Lushan earthquake. This increased level of earthquake monitoring has provided a dense array of coseismic recordings of the Lushan earthquake. These data have been used for numerous studies of the source properties, aftershock distribution, and the crustal strain field associated with this earthquake (Fang et al., 2013; Liu et al., 2013; Shan et al., 2013; Xie et al., 2013, 2014; Xu et al., 2013; Han et al., 2014; Zhang et al., 2014).
