摘　　要：2012年2月2日辽宁省营口市柳树镇发生ML4.5级地震,辽宁省强震动台网有6个强震台站记录到了该次地震的地面运动,记录的最大加速度峰值为138.7cm/s2。通过对此次强震记录的地震波频谱特征、震源机制、震源参数和地震烈度的分析认为:加速度峰值反映的烈度与实际震害现象反映出的结果基本一致,能够为地震震害特征、震源过程和震区的地震动特征研究提供依据。ME4.5 earthquake occurred at Liushu Town of Yingkou City, Liaoning Province on Feb. 2nd,2012. There are six strong motion stations in Liaoning strong motion network, which had recorded the ground motion of this earthquake. The largest peak ground acceleration is 138.7cm/s2. Based on the analysis of the spectrum signature, focal mechanism, source parameter and seismic intensity, it shows that the intensity reflected by the peak ground acceleration is consistent with the factual damage. This can provide data for the earthquake damage characteristics, the seismic source process and the ground motion features at the earthquake region.
