Description To investigate the genesis of the intraplate volcanism, we constrained the upper mantle deformation pattern by measuring shear wave splitting (SWS) parameters recorded by three NW-SE linear seismic arrays (NCISP6, NCISP10, NCISP11) in northeast China. Earthquake events used for SWS analysis were selected with magnitudes ≥ 5.5 at epicentral distances between 85°and 150°. Teleseismic SKS, SKKS and PKS phases were used to measure the receiver side seismic anisotropy. The database is stored in the directories with SAC files as:
(e.g., ./XKS-data/NCISP6/2007.
Some earthquake events produced both SKS and SKKS phases used for SWS analysis. Then the waveforms contain SKKS phases are named as YYYY.DDD.HH.MM.SS.skks.station.bh*

Date NCISP6: 2007/09-2008/09, NCISP10: 2016/10-2018/07, NCISP11: 2018/08-2019/12
Type The three component waveforms are stored with a sampling rate of 40 Hz and length of 100 sec (30 sec before and 70 sec after the theoretical XKS arrival time predicted by the reference model IASP91).
Format standard SAC format, can be read directly using sac, Obspy, MATLAB, et al.
