- Abstract:
- Abstract:the primary component analysis is made using 6 seismicity parameters of earthquake frequency N(ML≥3.0),b,η,A(b),Mf,Ac,which had relation to the earthquake strenth,it was achieved to reduce the above-metioned parameters effectively.There were some relativities among the 6 parameters and each one was different in distinct stages,but the earthquake intensity synthetic index W can be gained by the primary component analysis.W value showed obvious anomalies before 14 shadow earthquakes occurred in the Northeast China area and returned to normal after that.It showed that the synthetic index W can reflect the anomalous characteristics of the seismicity.
