摘要:

在卫星图像解译的基础上,对泰安地区5条主要断裂进行了野外地质地貌考察和年代学研究,发现泰山山前断裂为晚更新世晚期活动断裂,最新活动时代为距今(1.42±0.12)×104a.然后,讨论了发生在公元前1831年的"泰山震"的发震构造,认为"泰山震"可能与泰山山前断裂活动有关,可能是一次没有地表破裂、震级小于6.5级的中等强度地震。

Abstract:

Based on explaining satellite pictures,five main faults in the Tai'an region,Shandong Province have been investigated According to age research,it is found that the piedmont fault of Taishan is a late Pleistoncene active fault with the latest active age of (1.42±12)×104a B.P. The seismogenic structure of the Taishan earthquake occurred in 1831 B.C. is discussed It is suggested that this earthquake may be related to the activities of the piedmont fault of Taishan and may be a medium earthquake (M ≤6.5) without surface ruptures
