| 摘 要： | 分析了广西ML4.5级以上地震前表征地震活动增强的5种地震活动性参数的时间扫描异常特征,结果表明,对这5种参数进行分析可以提取中等地震前的异常信息,而且异常明显,说明这些地震活动性参数对广西未来中强地震的趋势分析有一定的预报意义,广西中等地震前地震活动性明显增强.

| Abstract: | The paper analyzed the anomaly characteristics of time scanning of 5 seismicty parameters indicating characteristics of seismic activity before moderate earthquakes with ML≥4.5 in Guangxi.The results show that the precursory anomalies appearing before moderate earthquakes can be recognized through the analysis on the 5 seismicty parameters;the anomalies are remarkable before moderate earthquakes.These seismicty parameters are meaningful for the prediction of the moderate earthquake.Seismic activity before moderate earthquakes in Guangxi was enhanced obviously. |
