长江三角洲及邻区新生地震断层的遥感地质探索

A EXPLORATION OF NEWBORN CONJUGATED TYPE EARTHQUAKE FAULTING FROM REMOTE SENSING GEOLOGY IN YANGTZE RIVER DELTA AND ADJACENT REGION

一、问题的提出提出这个问题是基于以下事实: 1.地震构造与现代构造研究的重大进展灾害对科学的挑战,往往导致科学的进步。例如1966—1976年期间,我国发生了一系列大地震事件,给我国人民带来了巨大灾难,人们向地震科学提出了严重的挑战。一般讲,地震是活动断裂的产物。然而,经历了上述大地震事件之后,我国著名地震构造专家丁国瑜教授作出了新的回答,地震断层有两类,一类是与已有的老断裂一致的,即各种活动断层。

Recounting the characteristics of conjugated shear fractures in this region and discussing the deep faulting possibilites of conjugated shear fractures and giving the signs for the deep conjugated shear fractures, as a result, the present auther regard the Nandu-shangpei conjugated shear frature group as a active deep conjugated shear fracture group and as the earthquake structure of Liyang earthquakes.
