中国大陆邻区的地震活动和中国大陆地震的关系

研究了３个方面的问题，一是中国大陆周边４个地震带地震活跃期与中国大陆地震活跃期的准同步性和它们目前的活动水平；二是欧亚地震带西部与中国大陆的地震活动呈出现明显的超前或滞后性；三是中国大陆邻区６个地震区的强震与中国大陆活跃期的开始或与中国大陆强震的对应关系。

RELATIONSHIP BETWEEN THE SEISMIC ACTIVITY IN THE CHINA MAINLAND AND THAT IN ITS NEIGHBORING AREA

Three aspects are discussed in this pater: (l)The quasi-synchronism between the seismically active periods in the China mainland and the seismically active periods of the four belts in its neighboring area; (2)The significant time correlation between seismic activity in the western Eurasia seismic belt and that in the China Mainland; (3)The parallelism between the strong earthquakes in six seismic zones of the neighboring area and the beginning of active periods of the China Mainland, or the strong earthquakes in the China Mainland. The results can be used to decide whether the seismically active period is to begin, whether the area to be in an active period, and to decide the recent seismicity level. There fore this work is more practical. The quasi-complementship between the seismicity in the western Eurasia seismic belts and that in the China Mainland needs studying deeply, which may reveal some new features of seismic sctivity.
