On the basis of the range of the Northeast seismic region, China, given in the popularizing software of China Earthquake Administration, we use wavelet analysis to study the characteristics of the seismic time sequence in the Northeast seismic region, and get the seismic active period of the region.

The PmP waveform data obtained from a deep seismic sounding profile, which ran through Zhangbei seismic region, were processed by means of both seismic wave complexity coefficient and frequency spectrum analysis methods, and the complexity characteristics of crust-mantle boundary beneath the studied area and its adjacent region were determined.
