  • A strong earthquake of Ms 6.5 occurred on the margin of the Tibetan plateau in a rural area of Ludian county (Fig. 1a), northeastern Yunnan Province, China, at 16:30 (Beijing Standard Time) on 03 August 2014. The epicenter (103.3° E, 27.1° N) was located at the intersection of the northwest-striking Baogunao-Xiaohe and northeast-trending Zhaotong-Ludian faults (Fig. 1b). The focal mechanisms of the mainshock and four strong aftershocks (Fig. 2) showed that this was a high dip angle, sinistral strike-slip event (http://www.eq-igl.ac.cn/wwwroot/c_000000090001/d_1406.html, last accessed August 2014; http://comcat.cr.usgs.gov/earthquakes/eventpage/usb000rzmg#scientific, last accessed September 2014; Fang et al., 2014).
