本文首次介绍了1913年8月19日冕宁小盐井6级地震的碑刻资料,并结合调查资料.考证了过去一些文献资料对本次地震灾害描述的诸多不实之处。重新圈定了地震等烈度线图,确认地震的宏观震中位于冕宁小盐井,震中烈度Ⅷ度,震级6级,宏观震源深度5.5千米。

In this paper, the data inscribed on a tablet about the M=6 Xiaoyanjing, Mianning earthquake in 19 Aug., 1913 was introduced for the first time. Combined with investigation data, we corrected many descriptions in some literature date of the past which were inconsistent with the facts of the earthquake disasters. Based onthe results mentioned-above, we charted once again curves of equal intensity of the earthquake and found that the macroseismic epicenter of the earthquake was located in Xiaoyanjing, MianningCounty, with the intensity being 8, the mangnitude being 6, and the macroseis- mic focal depth being 5.5Km.
