1303年9月17日在欧亚板块内部的中国山西省发生了一次毁灭性地震。它是地震界迄今所公认的8级大震中年代最早的,也是15世纪以前世界上死亡人数最多、记载较完整的一次特大地震。该震使山西省大部分地区遭到了严重破坏,陕西、河南、河北等省的一些州、县遭到了不同程度的破坏。共死亡27万至47万人,伤者数十万众。经考查,发震时间在1303年9月17日地方时间晚8时左右(即元朝大德七年八月初六日戌时),震中位置在北纬36°18.5′,东经111°46.5′(即今洪洞县和霍县之间,元朝时为赵城县境);震中烈度为11度,震级8.1级,震源深度29公里,发震断层的走向为 N13°E 倾向 S77°E。 September 17, 1303 A devastating earthquake struck Shanxi Province in the interior of the Eurasian Plateau. It is the earliest of the eight major earthquakes recognized by the seismological community so far and the largest and most complete earthquake ever recorded before the 15th century in the world. The earthquake has severely damaged most parts of Shanxi Province, and some states and counties in Shaanxi, Henan and Hebei provinces have been damaged to varying degrees. A total of 270,000 to 470,000 people died, hundreds of thousands of people were wounded. After examination, the time of the onset of the seismology was about 8 pm local time on September 17, 1303 (ie, when the Yuan Dynasty dynasty was opened in August, August 6, Xu period), its epicenter was at 36 ° 18.5 ’north latitude and 111 ° 46.5 east longitude Dongxian County and Huoxian County and Zhaocheng County in the Yuan Dynasty). The epicentral intensity was 11 degrees, the magnitude 8.1 and the epicenter depth 29 km. The strike of the seismogenic fault was N77 ° E and S77 ° E.
