| Abstract: | In this paper, structure models of the crust and upper mantle beneath each station have been obtained by way of fitting synthetic seismograms with P waveforms of deep focus teleseismic records from the 11 stations in the Northeastern Region of China. We have studied the structure in the region based on those models. Our results show that the medium of the crust and upper mantle is a layered structure with alternate high and low velocity layers within about 100 km under the region. The crustal thickness is about 31.8-35.8km. |
