Based on the PingguoM4.5 earthquake damage and seismic characteristics of seismic precursor anomaly analysis.The knowledge of damage characteristics, seismic geology, seismic sequence and seismic precursory data of the region are accumulated. The result has certain guiding signiifcance for earthquake prediction, earthquake emergency prediction work. This earthquake, occurred on F2 fracture of North West Zone in western Guangxi strong earthquake active area, belongs to isolated type earthquake sequence. The fault zone is with sinistral thrust characteristics. The earthquake was felt in large range and with wide spread effect. The intensity of the earthquake in epicenter area isVI+, once again relfecting the disaster characteristics of low magnitude, high intensity and serious damage in Guangxi region. Then from the temporal and spatial distribution of earthquakes, parameter of frequency and total fault area, stress drop before and after the earthquake, significant earthquake characteristics and precursory anomalies, the precursory anomaly characteristics of Pingguo earthquake are studied. The results showed that, before the earthquake, precursory anomalies of seismic activity spatial-temporal image, parameter value of seismology, geomagnetism and water level etc are very remarkable. The occurrence of medium and short term anomalies assorted.%通过对平果4.5级地震震害及地震前兆异常特征分析，积累该地区的震害特征、地震地质、地震序列、地震前兆等资料，对地震应急、地震预测预报工作有一定指导意义。此次地震属于孤立型地震序列，发生在广西西部中强地震活跃地区NW向百色—合浦断裂带上，该断裂带具有左旋逆冲特征，震感范围大，影响波及面广，震中烈度达Ⅵ+，造成较大破坏，体现了广西地区“低震级、高烈度、灾害大”的震害特征。从小震活动的时空分布、频度及断层总面积参数、大震前后应力降变化、显著地震特征及地震前兆异常出发，分析平果4.5级地震前兆异常特征，研究结果表明，平果4.5级地震前，地震活动时空图像、测震学指标、地磁及水位等前兆异常比较显著，中期、短期异常配套出现。
