摘要
本文利用加卸载响应比方法研究了云南省普洱地区ＭＬ６．０级以上地震前的加卸载响应比随时间的变化，计算了这个地区近期的加卸载响应比。结果显示，普洱地区６级以上地震前Ｙ值出现明显异常，近期的Ｙ值显示异常，表明该地区或在以其为中心方圆１００－２００公里的区域内在１９９５年或稍长时间内发生６．０级以上的地震的可能性很大。
Variations of response ratios of load and unload with time before ML ≥ 6 in Yunnan's Pu'er area have been studied in this paper. Response ratios of load and unload in recent period in this area were calculated. The results show that clear Y value anomalies appeared before M ≥ 6 earthquakes in Pu'er area. There exist Y value anomolies recently that indicate the high Possibility of M ≥6 earthquakes within 100 - 200 km in 1995 or longer.
