ANALYSIS TO THE PREDICTION EFFECT OF SEISMOLOGICAL PARAMETERS IN NORTH CHINA AREA
The earthquake-lack curve from Jan.1,1980 to Dec.31,1999,frequency and continuous calm time of M4 earthquake are analyzed,and its prediction ability for medium and strong earthquakes is studied.The results show that the successful rate of prediction to the three parameters is between 58% to 61%,false rate is in 28% to 33%,and R>R0.Thus the three parameters have good prediction effect.
