The study conducted an earthquake archaeological research in recent four archaeological excavation sites in Shandong,focusimg on the identification and analysis of tectonic deformation phenomena. Non-tectonic deformation phenomena were found in the Daxingzhuang site of the Shan Dynasty in Jinan suburbs. In the Longshan cultural layers,Chengziya site,Zhangqiu City,sand veins filling fracture were recognized. Sand veins on the tank wall and sand pipe density on the tank bottom were found at the Shan and Zhou Dynasty cultural strata in Qinhuangtai,Binzhou City. The tectonic cause and non-tectonic cracks were identified in the walls of the former Qi City,Linzi. In Rizhao City,the parallel distribution of sand vein fracture groups were found at the Yaowangcheng site of the Jianlongshan-Warring States-Han Dynasties. Typical conjugate shear fractures were identified in city walls of the former Xue City in Tengzhou city. The above natural deformation phenomena appeared concentrated in the culture layer of the Spring and Autumn-the Warring States-the Han Dynasties and before,and characterized by the seismic liquefaction of sands and other traces,which indicates that the region might well be in seismic active periods. The above inference was partly confirmed by the data microscopic analysis.
