Based on the Morlet complex wavelet transformation, the authors put forward a kind of new method for distinguishing periods of seismic activity and quietude and
Wave equation migration is often applied to solve seismic imaging problems. Usually, the finite difference method is used to obtain the numerical solution of th
Based on the Morlet wavelet transform and digital data from the Fushun and Beizhen seismic stations, Liaoning Province, we put forward a new method in the paper
