| 摘 要： | Introduction A great earthquake occurred on Sept. 25 of 1303 (Seventh of Dade, Yuan Dynasty) around Zhaocheng and Hongtong in Shanxi Province. The great earthquake is a very famous one, which is affirmed as the first earthquake with magnitude 8 in Chinese history. The catastrophes took place; meanwhile, huge archives of the disaster were recorded. According to these disaster recordings, the first isoseismal map in China was delineated, which provide us with abundant information of intensi…

| Abstract: | In this paper, we calculated the seismic pattern of instrumental recorded small and moderate earthquakes near the epicenter of the 1303 Hongtong M=8 earthquake, Shanxi Province. According to the spatial distribution of small and moderate earthquakes, 6 seismic dense zones are delineated. Temporal distribution of ML2 earthquakes since 1970 in each seismic dense zone has been analyzed. Based on temporal distribution characteristics and historical earthquake activity, three types of seismicities are proposed. The relationship between seismic types and crustal medium is analyzed. The mechanism of three types is discussed. Finity of strong earthquake recurrence is pro-posed. Seismic hazard in mid-long term and diversity of earthquake disaster in Shanxi seismic belt are discussed. |
