Receiver structure beneath the Chinese Digital Seismograph Network (CDSN) stations: Preliminary results. Scientific report No. 1
This report provides preliminary results of an investigation of the crust and upper-mantle seismic velocity structure beneath the China Digital Seismograph Network (CDSN). Receiver functions obtained from over 100 teleseismic events were stacked by common back-azimuth and epicentral distance and inverted for the velocity structure beneath 5 CDSN stations. ne inversion results show that stations HIA and BJI have well constrained crustal models of about 40-km thickness with gradational Mohos. At WMQ there is evidence for shallow dipping structure and the inversion results indicate a smooth positive gradient in the crust with a transitional crust-mantle boundary. Model estimates for KMI and LZH are poorly constrained by the data analyzed thus far. Synthetic seismograms of 5 CDSN crustal models for the Soviet JVE nuclear test indicate that the receiver structure most strongly affects the radial component of the recorded P wave.
