Abstract:: By referring to the Earthquake Records of the Annals of Shaanxi Province,the China Earthquake Catalogue,and other historical materials,we obtain the earthquake frequency,location,magnitude,and earthquake disasters in Guanzhong region during the Ming and the Qing Dynasties(1368-1912).Through index statistics,sliding average and semantic difference analysis,we draw the map of the temporal and spatial variation of the earthquake disasters in Guanzhong region and further analyze the characteristics of the variation.The results show that:①The earthquakes during the Ming and the Qing Dynasties are significantly characterized as periodic,chronical,and seasonal changes.Earthquakes in this region were relatively active in the period from 1474 to 1676.The earthquakes occurred most frequently in 1480s and 1500s,especially in the Summer of these specific years.②The earthquake epicenters were mainly distributed in the central and eastern parts of Guanzhong region,then gradually scattered along with time,followed with the weakening of the frequency and intensity.③In Guanzhong region,the high incidence period of the historical earthquakes fell in the second active period of the Fenhe-Weihe earthquake zone,and the earthquakes distributed dense in the east and sparse in the west.Due to superposition effect of disasters,social unrest and economic situation,the case of “small earthquakes causing major disasters” occur from time to time.
