| Abstract: | The magnitude of the earthquake, which occurred in the northwestern of Fangxian County of Hubei Province in 788 A.D., has not been exactly determined because of inadequate historical evidences. In this paper we analyzed the historical earthquake document, the regional earthquakes recorded by seismometers, the historical materials of multi-field and seismo-tectonic background in the neighboring area. Finally, the magnitude of this earthquake is re-determined as MS6¾. |
