广西地震活动与我国主要地震区(带)地震活动的相关分析
|
摘要
应用灰色系统理论的关联分析方法研究了广西地震活动与我国主要地震区（带）地震活动的相关性．结果表明广西地震活动与东南沿海地震带地震活动的关联程度最大（ｒ＝０．８６），根据这一结果，对广西与东南沿海地震带的地震活动的相关性作了进一步探讨，发现本世纪以来广西地震活动与东南沿海地震带的地震活动同步起伏，两区（带）之间发生中强地震的互相对应关系特别明显．
n this paper,the correlativity of seismic activity in Guangxi with those in the master seismic zones (belts) of China has been studied by using correlative analysis method of grey system theory.The results show that the degree of association of seismic activity is the largest between the Guangxi seismic zone and the southeast coastal seismic belt (r=0.86). Based on the results,the correlativity of seismic activity in the Guangxi seismic zone with that in the southeast coastal seismic belt has been discussed further.It is found out that the change of seismic activity has been synchronous in the Guangxi seismic zone and in the southeast coastal seismic belt since 1900,and that the correspondence relation of moderately strong earthquakes in the zone with those in the belt is very obvious.
