Seismological archeology is an interdisciplinary study of archeology and seismology that studies the ancient earthquakes of archeological sites using seismic，geological, and archeological methods.It enriches the understanding of the laws of seismic activities，and thereby provides information for seismic deformation phenomenon analysis，earthquake prediction，and seismic hazard assessment.According to historical records，eastern China underwent moderate and strong seismic activity，but there is a lack of historical records and even less information on its prehistoric seismological archeology.The eastern China area，across the Qinling-Dabie collision zone，falls mostly in the North China plate and Southern China plate boundary zones，and its prehistoric earthquake activity is worthy of study.Based on the above considerations and with the support of the China Earthquake Administration industry-scientific special project “Recognition and study of prehistoric earthquakes in the North China and Southern China border belt，” we conducted cooperative research in seismic archeology with the departments of cultural relics and archeology.The Jianghuai area is located at the intersection of the Qinling-Dabie collision zone and the Tan-lu fault zone，and it is a highly significant area for the study of its prehistoric earthquake events.We conducted earthquake archaeological research in four archeological excavations sites in the Jianghuai region and found abundant tectonic deformation phenomena，including newly discovered ancient seismic events.The four archeological sites are the Guzhen Xiaolijia site，Hefei Luandunzi site，Hexian Dachengzi site，and Maanshan Shendong site.The Guzhen Xiaolijia and Hefei Luandunzi sites revealed continuous tectonic deformation characteristics of ancient ruins，pointing to their relationship with earthquakes.The results show that most earth-pit tombs of the Hefei Luandunzi site are in irregular deformation，but the deformation of M66 is obviously affected by the Tan-lu fault dextral slip traction formation，which also has nothing to do with the seismic loads.The excavation exposed some ancient earthquake ruins in the Hexian Dachengzi and Maanshan Shendong sites，which mainly include earthquake fissures，cultural layer dislocation，and fold phenomenon.Many earthquake fissures were found in the Hexian Dachengzi site，with the fracture filled with black yellow powder sand，the sand source for the underlying silty strata；the crack length is 0.5~3 m and width is 2~5 cm.Based on the stratigraphic horizontal relationship，these cracks were determined to have developed in the （10） and（5）layers.In order to establish the time the seismic event occurred，we collected six 14C samples in the（11），（10），and （5）layers.Three samples were sent to BETA laboratory in the USA for testing.Sample test results show that the ages for the（11），（10），and（5）layers are （2 990±30） BP，（2 760±30） BP，and （2 580±30） BP，respectively.Thus，the earthquake occurred between（2 580±30） BP and （2 760±30） BP，with a calendar age of 760~980 BC，during the middle to late Western Zhou Dynasty.At the Maanshan Shendong site，an earthquake fissure was found with a bottomless crack terminating in the middle part of the cultural layer.By archeologically dating the cultural layer and the cutting relationship between the earthquake fissure and the cultural layer，we identified a paleoearthquake event which also occurred in the middle to late Western Zhou Dynasty.Comprehensive research results of this ancient earthquake with the previous research in the Jianghuai region of the Western Zhou Dynasty suggest that the Jianghuai area in the middle to late Western Zhou experienced a moderate strong earthquake activity period.
