【摘要】 地震活动的平静现象可分为4种:无震平静和震后平静可归于非前兆性平静;震前平静和场兆平静则可归于前兆性平静。本文分类统计了南天山地震带东、西段的地震平静现象,分析了平静特征及其与主震的关系。平静的层次性特点有助于判定未来震级和地点。更多还原

【Abstract】 There are four types of seismic quiescence: Non-earthquake quiescence and quiescence after-earthquake are regarded as non-precursor quiescence,quiescence before earthquake and field-precursor quiescence are precursor quiescence.In this paper,the seismic quiescence phenomena in the both eastern and western part of southern Tianshan seismic belt are statistically divided in different types,the characteristics of the quiescence and relationship with mainshoch are analyzed.Research on the characters for different seismic quiescence level is helpful for judging the magnitude and position of future earthquake.更多还原
