by Lihua Fang, Jianping Wu, Jie Liu, Jia Cheng, Changsheng Jiang, Libo Han, Yushi Wang, Kun Chen, Xu Zhao, and Zhongliang Wu

The electronic supplement includes five figures and three tables. Table S1 is the Kangding Ms 6.3 earthquake sequence catalog relocated using hypoDD, Table S2 provides the parameters of the ruptured event on the Xianshuihe fault since 1893, and Table S3 provides the parameters used in the calculation of coulomb stress change.

Figures

Figure S1. Source time function of the Ms 6.3 Kangding earthquake. The moment rate function is obtained using the method developed by Zhang et al. (2012). The result shows that most of the seismic moment is released in the first 5 s.

Figure S2. Magnitude–time plot of the Ms 6.3 Kangding earthquake sequence. Zero on the x axis indicates the origin time of the Ms 6.3 earthquake.

Figure S3. (a) Acceleration time histories and (b) velocity time histories for the Ms 6.3 Kangding earthquake recorded at station 51KDX. Strong ground motion lasted about 10 s. (Data source: China Strong Motion Networks Center.)

Figure S4. Spectral accelerations of the Ms 6.3 Kangding earthquake and the Ms 5.8 earthquake recorded at station 51KDX.

Figure S5. Damage of typical buildings located in different intensity zones. (a) Damage of a frame structure in Tagong town, Kangding county (Chinese Seismic intensity VIII). (b) Collapse of a stone and wooden house in Xiede town, Daofu county (intensity VIII). (c) Fracture of a brick and concrete house in Yala town, Kangding county (intensity VII). (d) Crack of a stone and wooden house in Xinduqiao town, Kangding county (intensity VI). (Data source: Field Investigation team of Sichuan Earthquake Administration.)

Tables

Table S1. Relocated aftershocks of the Kangding earthquake. Aftershock catalog of the Kangding Ms 6.3 earthquake relocated using hypoDD from 22 November to 15 December 2014. All times are in local time for Beijing (UTC+08:00). The following are the descriptions for each column in the table: ID number assigned to the event, latitude of the earthquake (° N), longitude of the earthquake (° E), depth of the earthquake (km), horizontal and vertical location error (m), origin time of the earthquake (Beijing time), magnitude (Ms), residual (s).

Download: Table S1 [Zipped Space-Delimited Text; ~26 KB]. The following are the descriptions for each column in the table: ID number assigned to the event; Lat, latitude of the earthquake (° N); Lon, longitude of the earthquake (° E); depth of the earthquake (km); EX, EY, and EZ, horizontal and vertical location error (m); origin time of the earthquake (Beijing time; yyyy, mm, ss.sss); MAG, magnitude (Ms); and RES, residual (s).

Table S2. Parameters of the ruptured event on the Xianshuihe fault since 1893. The parameters are modified from Cheng et al. (2011).

Table S3. Parameters used in the calculation of coulomb stress change.
