ANALYSIS AND TEXTUAL RESEARCH OF THE SEISMOGENIC STRUCTURE OF THE QIN-LONG EARTHQUAKE IN 600 A.D.
摘要
Abstract
According to Chinese historical records, an earthquake struck the ancient Qin-Long area in 600 A.D., and caused serious social impact.The epicenter, earthquake magnitude, epicentral intensity,and seismogenic structure of this earthquake have long been disputed.In this study,based on the earthquake collapses found in Guguan town, Longxian county, combined with multiple research methods including historical data verification, satellite images interpretation, field observation, geologic trench excavation,age dating, it shows that the seismogenic structure of the earthquake is the Guguan segment of east Liupanshan fault, and the epicenter should be located near Guguan town, Longxian county.Its magnitude was around 6爸4 and the epicentral intensity was inferred asⅨ.This study on the historical earthquake in this area has great significance to the earthquake hazard assessment in Liupanshan area and the understanding of the kinetic process of the northeastward expanding of the Tibet Plateau.关键词
