前言1290年9月27日(元世祖至元二十七年八月癸巳)夜,在今内蒙古宁城县大明乡附近发生了一次强烈地震。这就是当时引起“人民震惊”的武平路地震。根据史料记载,1971年出版的《中国地震目录》将这次地震定为6(3/4)级,震中烈度九度。武平路地震是元代三大地震中为首的一个,是华北地震平静期进入第二个活跃期的转折点。这次地震所处的宁城一义县地震带1)的中强地震活动,在历史上与山西地震带的中强地震活动,有较密切的呼应关系。因此,有必要对这次地震进一步做些探讨。本文根据最近对武平路地震极震区大明塔震害调查考证2)及对某些史料的重新评定,对武平路地震的震级
Foreword In the night of Sept. 27, 1290 (Yuan Shizu to Yuan twenty-seven years of August), a strong earthquake occurred near Daming Township, Ningcheng County, Inner Mongolia this night. This is the Wuping Earthquake that caused “people’s shock at that time.” According to historical records, the “Earthquake Catalog of China” published in 1971 set the earthquake as 6 (3/4) and its intensity was nine degrees. The Wuping Road earthquake was one of the three major earthquakes in the Yuan Dynasty and the turning point for the second active period of the North China quake. The strong earthquake activity in Yiwu County earthquake zone located in Ningxia in this earthquake has a close relationship with the moderately strong earthquake activity in the history of Shanxi earthquake zone. Therefore, it is necessary to further explore the earthquake. Based on the recent investigation of the Da Ming Pagoda in the Wuping Road earthquake and its earthquake zone 2) and the reevaluation of some historical data, the magnitude of the Wupinglu earthquake
