摘要

以地震应变能作为响应因子,研究了1997至2007年赣粤闽交界及邻区4.0级(ML≥4.0)以上中强地震临震前的加卸载响应比(Y值)的基本变化特征,研究结果表明,80%以上的地震在临震前Y值呈现出高值异常形态。因而它可以作为此地区地震预测的一种手段。
The 1oad-unload response ratio theory (LURR), risen up at the end of 1980s, has now become a mature and efficient method of earthquake prediction. In this paper, using the seismic strain energy as the response factor,we study the anomalous characteristics of the 1oad-unload response ratios(Y) before moderate-strong earthquakes (ML≥4.0) from 1997 to 2007 in the adjacent area of Jiangxi, Guangdong and Fujian provinces.The result shows that for more than 80 percent cases, obvious anomalous high-value response ratios (Y) occurred. Therefore, the LURR method appears to be an effective method of earthquake prediction for this area.
