本文依据1057年历史地震文献资料,在分析这次地震的发生时间和破坏情况的基础上,对这次地震的震中参数提出了新的认识:1057年在河北—北京一带发生了二次地震,第一次地震发生在1057年3月26日,震级为534级;第二次地震发生在1057年5月24日,震级为612级;二次地震的震中位于现固安—霸县一带,其地理坐标为北纬39.25,东经116.3。

Abstract Based on the historical document and analysis of the information on the damage situation, we propose new parameters for two historical earthquakes of 1507 in this paper. The first one occurred on March 26 with amagnitude of 5 3/4and the second one occurred on May 24 with a magnitude of 6 1/2 The earthquake epicenter ofthese two events are located at 39.25°N, 116.3°E, which is in the region of Guan and Baxian county at present.
