通过对活断裂填图所获资料分析，结果表明：安宁河活断裂最新的断错断续长度达30千米。它不仅存在于1536年强震宏观破坏高烈度区中部，而且还在近中部的沙尔村发现左旋水平扭错约千米左右的次级冲沟。据此可以确认：1536年西昌-冕宁间发生的强震，震中位于泸沽南的沙尔村附近，震中区北起冕宁的高山堡，南至西昌的新华，长约30千米；震中烈度Ⅹ度。用多种方法和公式计算，其震级约为级。
Through the analysis of the data obtained from the mapping of live fractures, the results show that the latest fault-breaking length of Anninghe active fault is up to 30 km. It not only exists in the middle part of the area with macroscopic damage and high intensity in strong earthquakes in 1536, but also found sub-gully in Lhasa village in the near middle of the country with about 25,000 km left-handed twist. Based on this, it can be confirmed that the strong earthquakes occurred between Xichang and Mianning in 1536, with the epicenter located near Shaer Village in Lugu South, the high mountain fortress of Mianning in the epicenter area and Xinhua in Xichang in the south, about 30 km in length; Intensity Ⅹ degrees. With a variety of methods and formulas, the magnitude is about level.
