| 摘 要： | 收集华北地区地下流体观测资料并进行系统分析,采用定量方法判定异常,对该区强震前的前兆异常特征进行了研究。提出地下流体存在着趋势上升型的中期异常和转折型的中短期异常,且不同地震的前兆异常图像具有相似性;依据大量异常资料,给出了华北地区中长期和中短期前兆异常的统计特征,以期能为华北地区年度会商的地震预测提供较为确切的依据。 |
| 关 键 词： | 地下流体 同一化 定量判定 前兆异常 华北地区 |

| Abstract: | Precursor anomaly characteristics before strong earthquakes in North China region are studied by the method of quantitatively determining anomalies based on systematic collection and analysis of observation data of underground fluid in this region.The results indicate that medium-term precursor anomalies with uptrend and medium-short-term with transition of underground fluid appeared before earthquakes,and precursor anomaly graphs were comparable before different earthquakes.Statistic characteristics of med... |
