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。
Seismic activities can be divided into four kinds of calm phenomenon: no seismostation and post-earthquake calm can be attributed to the non-precursory calm; seismostasis and seismost calm can be attributed to the precocious calm. This paper classified the seismological calm phenomenon in the east and west segments of the southern Tianshan seismic belt by classification and analyzed the serene features and their relationship with the main shock. Calm hierarchical features help determine future magnitude and location.
