摘要
本文以统计学方法,对福建近1030a(公元963~1992)M≥4.75级地震,作了时序与统计相关的研究,结果表明:(1)福建M≥4.75级地震的频度关系为N=20.8374-2.786SM;(2)M≥4.75级地震空间分布不均,79%出现在25°N以南,并有三个密集带;(3)M≥4.75级地震有明.显的活跃期与平静期,震中迁移也有一定规律;(4)福建明显的春暖夏凉年之后5a内易发强震;(5)福建洪涝与强震具有年耦合性。
築ased on earhquakes (M≥4. 75) of last 1030 a (963~ 1992,A. D. ) in Fujian, usingstatistical method, this paper studies time series and statistical dependence. The resultsshow:(1) The relation between earthquake frequency and intensity is: N= 20. 8374- 2. 7868M(2)The distribution of earthquake (M≥4. 75) in not uniform in Fujian, with 79% locating insouth of 250N, in three belts. (3) The earthquake (M≥4. 75) had obvious active time andstationary time,The transfer of epicentre has its own regulations. (4) If the climate is obvious warm in spring and cold in summer in Fujian, strong earthquakes may happen in after 5a. (5) There is an annual coupling between flood and earthquake.
