云南地区1995～1996年三次强震爆发的共性研究

COMMON FEATURES OF THREE STRONG EARTHQUAKES IN YUNNAN AREA IN 1995～1996

论述了在1995～1996年云南地区发生的孟连西南7．3级、武定6．5级和丽江7.0级3次强烈地震的孕育过程中，近源区中小地震的异常增频特点和临震前大气压力的突变共性，并据此提出，强震的发生乃是地壳内外动力涨落加剧的结果。

After discussing the features of anomaly frequency increasing of moderate-small earthquakes of near-source area in the earthquake preparation processes of Menglian M= 7. 3, Wuding M= 6. 5 and Lijiang M= 7. 0 three strong earthquakes, and its common feature of atmospheric pressure mutation of impending.. earthquake, it. is proposed that the occurrence of strong earthquake is the result from the violent fluctuation of motive power of inter-external crust.
