Abstract

Abstract: A deep sounding work by converted waves of earthquakes has been conducted in Xingtaiearthquake region. As a result, 6 cross-sections of deep structure in Xingtai earthquake area have been constructed (3 in NW trend and others in NE trend). On the bases of these sections the structures of major deep crustal interfaces G,C and M were determined. At the same time, the velocity models of P and S waves were constructed. Moreover, background of 3-D deep structure and the dynamic conditions for earthquake occurrence are also discussed.

Key words: Xingtai earthquake, Deep structure, Converted earthquake wave sounding, Earthquake preparation conditions

摘要： 在邢台地震区开展了地震转换波测深工作,得出了6条深部构造剖面图,其中包括3条NW向和3条NE向剖面,同时也得出了地壳内G、C和M3个主要深部界面的埋深分布图以及地壳内波速分布模型。在此基础上讨论了邢台强震发生的深部三维构造背景和深部孕震条件。
