摘要: 由短期、长距离、线性震中迁移线交汇得到的稳定交汇区进行强震地点预报方法称为线性震中迁移交汇法。存在由源向场的迁移、由场向源的迁移及过源迁移3种迁移类型。这3种迁移的总特征是在未来震源区和其附近形成稳定的交汇区。着重讨论“交汇法”的物理基础,并用实例进行证明。

Abstract: The method of loeation predietion of stronge arthquakes using stable interseetion regions of the linear epieenter migration traek with short time and long distance,is ealled ”theinterseetionmethod”.There are three kinds of migration types:the first is from source to field; the second is from field to source and the third is to pass through the source regions.The main charaeteristies of those three kinds of migration are that this interseetion region will be the stabl site where future earthquake will oeeur in or near the region.Physieal foundation of”interseetionmethod”is diseussed in this paper,and some examples of earthquakes are verlfied.

Key words: Linear epieenter migration, Strong earthquake, Loeation predietlon
