摘要: 本文着重研究了近代工程施工中发现的大量震害遗迹, 诸如断层、裂缝、喷水冒砂现象, 诱发滑坡和坠入地震断裂带中的木炭与文物.又经考古研究和 C14鉴定属明代之物, 证实这条在极震区延伸大于70公里的破裂带就是这次大地震极震区地面破裂带.Abstract: In the present paper, a large number of vestiges of earthquake damage, discovered in engineering works: in recent times, such as faults, fissures, phenomena of water and sand eruption, induced eboulements, charcoal and cultural relics fallen in earthquake fault zones, are studied. By means of archaeological study and verification of C14, it is proved that those mentioned above might originate in the Ming Dynasty and that the rupture zone extended for more than 70 kilometres in the meizoseismal area is the very ground rupture zone of the meizoseismal area of this large earthquake.
