摘　　要：据历史记载１５００年在宜良一带发生了一次强烈地震，由于前人对该次地震无较详细的现场实地考查资料，因此对这次地震认识说法不一。１９９２年作者对该次地震进行了实地考证。发现和确认了这次地震十分丰富的地震地表形变带，现存长度达８１公里，最大左旋水平位错量９至１１米。研究结果表明该次地震的发震构造为小新街－徐家渡断裂，震级接近８级。A strong earthquake happened around Yiliang county in 1500 according to historical records. Recognization to this earthquake has been different,because predecessors did not make detailed site investigation. The authors made site textural research to the earthquake in 1992, found and confirmed some useful data that there existed a lot of surface deformation belts with existing length of 81 km and 9-1lm of maximum left lateral level dislocation. The results show that earthquake-generating structure was Xiaoxinjie-Xujiadu faults, magnitude close to 8.
