摘要
本文在研究了中国及东亚地区的地震资料后，指出：东亚地区存在５２—５３年的地震重复周期。简称东亚地区强震活动的５０年周期。在进一步研究后，发现根据全球８级以上的巨大地震的矩震级来看，全球地震活动亦存在５４年的周期。从而表明了东亚地震活动与全球地震活动之间的联系。
After studing seismic data from China and East Asia region, this paper points out there is an earthquake recurrence period of 52-53 years in East Asia region, which is brifly called the 50-year cycle of strong seismicity in East Asia. Further study finds there is also a 50-year cycle of seismicity in globe according to the moment magnitudes of large earthquakes with M≥8 in globe, and then the tie between seismicity in East Asia and globe is showed.
