摘要
本文将全球地震活动存在的二个主要地震带,即环太平洋地震带和地中海—南亚地震带划分为8个地震活动区,利用“追踪”统计法,统计出这8个区Ms≥7.0地震转移的相关频率,并就相邻两次强震的间隔时间进行了分析,认为全球强震具有一定的区域转移特点,在时间间隔上具有发震的优势日。
The existing two major seismic zones in the world, e.i. the Circum-Pacific and the Me-diteranean-South-Asian seismic zones are divided into eight seismically active regions in this paper. The author here has counted the correlative frequency of earthquake (Ms≥7.0) migra-tions in the eight regions using 'trace statistics'. According to the analytical results of the time interval between each two adjacent strong shocks, the author suggests that the global strong shocks are of characteristics of regional migrations, and that there are causative dates domina-ted in the time'interval.
