浅析北天山西段与南天山中东段地震活动关系
|
摘要
对比分析了北天山西段与南天山中东段的地震活动关系,发现1935年以来两区地震活动水平相近,中强以上地震具有交替活动的特征,且有一定的成组性南北迁移的规律。时空扫描分析发现,北天山西段新源—温泉附近地区的中小地震集中活动对南天山东段中强地震的发生具有一定的前兆意义,南天山东段的4级地震频度的减小与北天山西段5级以上地震有一定的对应关系。并在一定程度上对两区域地震活动存在的以上规律和对应关系进行了分析。
To contrast and analyze the relations of seismic activity between west of North Tianshan and mideast of South Tianshan,I discovered that the level of seismic activities is similar in the two areas since 1935.And the mid-strong or more than earthquakes have in turn active characteristic.They also have certainly the group migration rule between southern and northern.By scanning and analyzing of space and time,I discovered that concentrative activity of mid-small earthquakes in Xinyuan-Wenquan nearby area of west of North Tianshan has a certain precursory significance to occurrence of mid-strong earthquakes in east of South Tianshan.And it is a certain corresponding relation between the frequency reduction of earthquakes with MS4 in east of South Tianshan and the occurrence of earthquakes with MS≥5 in west of North Tianshan.In a certain extent,I analyzed the above-mentioned rule and the corresponding relation of seismic activities existed in these two areas.
