Other AbstractThe Load/Unload Response Ratio (LURR) theory is a new method in earthquake prediction. LURR is defined as the medium's response to loading divided by the response to unloading. For the earth medium, the earth tide provides a natrual way to load and unload. Benioff strain is selected as the response quantity. Through space-time scanning in Chinese mainland as well as other regions, the abnormal region where an earthquake may occur can be got. Then we hope the LURR in the abnormal rigon can reflect the preparation process of earthquake through depicting the damage of seismogenic zone, and then predict earthquake. It's about thirty years since LURR was put forward. These years many people have done a series research on LURR, and have got some achievements. In practice of earthquake prediction, LURR has achieved success to some extent. Many earthquakes occurred in the abnormal zones from LURR's space-time scanning. But the result is not as good as we wished, the main reason is that we don't consider the geophysical condition enough. In this paper, we conbine dimensional analysis with LURR method, considering the local geophysical condition, for example the shear strain rate and the average seismic wave energy etc. Using the data of 34 seismic cases which occured in Chinese mainland since 1970, we obtain two dimensionless quantities pi(1) and pi(3) related with the earthquake magnitude and occurrence time. Through the process of data fitting, the relationships between pi(1) and magnitude and between pi(3) and occurrence time have been obtained. Applying the result to earthquake prediction, we should determine the seismogenic zone according to LURR's spce-time scanning result at first;then after determining the geophysical parameters of the specific seismogenic zone, we can get the magnitude and the the occurrence time for the future earthquake through pi(1) and pi(3) separately.
