隐伏冲断层是加利福尼亚南部灾害地震的起源 ,１９９４年的Ｎｏｒｔｈｒｉｄｇｅ（６．７级地震）事件造成洛杉矶市３５０亿美元的损失 ,说明了这种冲断层的厉害程度。有人认为洛杉矶盆地大部分地区下面有类似的隐伏冲断层。本文根据对１００００多公里地震反射资料的分析结果
Hidden thrust is the origin of a disaster in southern California. The Northridge earthquake of 1994 caused a loss of 35 billion U.S. dollars in Los Angeles, indicating the powerfulness of this thrust. Some believe that much of the Los Angeles basin below has similar hidden faults. Based on the analysis of more than 10,000 km seismic reflection data
