Fan Yeping ( Liaoning Seismological Bureau )
Processing a real-time earthquake by computer. one of the key to the settlement of calculating the epicenter and other parameters lies in correct identification of distant earthquake from near ones. This paper mainly discuses and analyses the method of distinguishing distant shock from near ones by using relationship between the period T of seismic wave and The Times of the real—time samples for arrival time. The formula is ?
