利用此比值常数以及由测震学指标所确定的T_1和求得的T_2可以进行确定性的中长期地震预报。
By means of this ratio and T_1, T_2, determined by seismometry, the mid long-term forecasting of earthquakes can be done.
The research result shows that this physical model is useful to determine the locked area along plate boundary faults and further to make the long term and middle term earthquake prediction.
