P-wave tomography and relation between shallow and deep structures beneath the Songliao basin

Abstract

We selected relative travel-time residuals from teleseismic waveform data using the waveform correction method and imaged the P wave velocity structure beneath Northeast China. In combination with other geophysical data, we discussed the relation between the shallow and deep structures of the area. The results show that there is a primary high-velocity zone with some high-and low-velocity distribution characters beneath the Songliao basin.
