Radial and Transverse receiver functions in Guangdong, Fujian, Jiangxi, Hunan, Guangxi Provinces in China.

Seismic data from 126 permanent seismic stations run by the China Earthquake Administration between 2009 and 2015 were processed. Teleseismic waveform recordings with a magnitude greater than M6.0 and epicentral distances ranging from 30° to 90° were considered. The back azimuth coverage of these events is overall adequate for anisotropy analysis . The RFs were computed following the source equalization procedure with a water-level parameter of 0.001 and a Gaussian width of 2.5. We manually evaluated these receiver functions by checking the Ps signals, and high-quality radial and transverse RFs were selected for further processing.
