【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。更多还原

【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)×10 4a 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更多还原
