运用ShakeMap中的计算方法，计算2012年7月20日江苏宝应M4.9地震的加速度场，结果发现，水平向峰值加速度的分布与真实的烈度分布基本一致，说明利用江苏省强震动台网43个固定台站的观测资料，可为快速评定此次地震的烈度提供科学、准确的参考信息。

Use ShakeMap calculation method, calculation of the acceleration field of Baoying M4.9 earthquake of July 20, 2012, found that the horizontal distribution of peak acceleration with real intensity distribution is consistent, strong motion Jiangsu Province the observations of 43 fixed stations in the network can provide scientific, accurate reference information for rapid assessment of the intensity of the earthquake.
