震群 meaning in English
earthquak swarm
earthquake swarms
swarm earthquake
Examples
- The spatio - temporal evolution characteristics of general earthquake swarms and precursory swarms before and after the tangshan earthquake
唐山大震前后一般震群与前兆震群时空演化特征研究 - We analyzed and studied the structure environment , the epicenter mechanisms of medium - strong earthquakes , time and space distribution of medium - strong earthquakes and the relation between the small earthquakes clusters around baicheng and medium - strong earthquakes in the seismic field of south tianshan mountain
摘要分析研究了南天山地震带构造环境、中强地震活动震源机制解、中强地震时空分布以及拜城周围小震群活动与中强地震的关系。 - Considering the ratio of non strike - slip faults and non mainshock - aftershock , yunnan area can be divided into four subareas with different characteristics , which are strike - slip mainshock - aftershock in central yunnan ( a1 ) , incline - slip swarm in northwestern yunnan ( a2 ) , strike - slip double shock in western yunnan ( b1 ) and quasi - strike - slip mainshock - aftershock in southwestern yunnan ( b2 ) , respectively
考虑到非走滑地震断层和非主余震型地震序列所占的比例，可以将云南地区划分为4个具有不同特点的分区：滇中( a1 )走滑主余震型区、滇西北( a2 )斜滑震群型区、滇西( b1 )走滑双震型区和滇西南( b2 )准走滑主余震型区。 - The result show , most of the medium - strong earthquakes faults are dip - slip reversed , distribution of the main stress p axis is sector from west to east ; there are large difference between kuche and baicheng region in seismic activities , but the characteristic of cluster is same in the two region ; the distribution of medium - strong earthquakes is nw direction in baicheng region , it show , there can have a concealed fault ; small earthquake clusters ' activities can reflect the effect that local medium - strong earthquakes to the secondary small structure around it
结果表明：南天山东段中强震震源断错以倾滑逆断为主，主压应力p轴由西到东呈扇形分布；相距较近的库车与拜城地区地震活动存在较大差异，但均存在明显的成丛性分布特点；拜城地区中强地震分布呈北西向可能预示著该区存在隐伏断裂，小震群活动则可能反映了局部中强震对周围次级小构造的影响。
