Study on the prediction of relatively strong aftershocks in earthquake sequence with least square fitting method;

The type of earthquake sequence and distribution characteristics in Ma anshan city and surroundings;

A review and discussion on earthquake sequence research;

In this paper the possibility and the specific method of CORA-3 pattern recognition algorithm are explored for the early synthetic judgement of seismic sequences of strong aftershocks,strong swarms and foreshock-mainshock-aftershock.

By means of Sato scattering of single model and Gaotai seismic station of the near-field digital seismic records,this paper studies the characteristics of Linze swarm sequence coda QC value,also draws a conclusion of QC value changing with frequency,which is QC(f)=(27.
