根据史料记载,各种地震目录均将东汉灵帝光和三年秋(公元180年)表氏地震震中定在甘肃省高台县西(39.4°N,99.5°E),震中烈度Ⅹ度,震级7(1/2).本文通过对历史地震资料的重新考证和表氏新旧县城遗址的实地考察,对公元180年表氏地震的震中位置作了如下修正:震前的表氏县城位于甘肃省肃南县明花区新墩子城,也应是震中所在地,其地理位置为39.6°N、99.3°E,精度2类;震后重建的县城在今骆驼城或草沟井城.通过对史料震害的认真分析,并将本次地震与两汉时期8次6(1/2)级以上地震及高台附近地区9次地震的地震参数、震害和波及范围进行对照,最终将震中烈度修正为Ⅸ—Ⅹ度,震级修正为7级.
According to historical records, all epicenters in the catalog of earthquakes recorded the epicenter of the epicenter of the Eastern Han Dynasty Emperor Lingguang and the Three Years Autumn (AD 180) in Gaotai County, Gansu Province (39.4 ° N, 99.5 ° E), the epicenter intensity Ⅹ degree, and the magnitude of 7 (1/2) .This paper revisits the historical seismic data and the site investigation of the old and new county towns in Tablets to make the following corrections to the epicenter of the 180 epoch: the epicenter of the epicenter before the earthquake was located in the Gansu Province, The new Dun-mei City in Minghua District of Nanning County should also be the epicenter of the epicenter with a geographic location of 39.6 ° N and an accuracy of 99.3 ° E. The county after reconstruction was located in this camel city or Caogujing, This earthquake was compared with the seismic parameters of 8 earthquakes of magnitude 6 (1/2) above the Han dynasty and 9 earthquakes in the vicinity of the high platform, the damage and the scope of the earthquake. Finally, the intensity of the epicenter was corrected to IX -X degrees, magnitude correction for 7.
