| 摘 要： | 阐述并分析了华北北部几个中强地震前地磁前兆异常的时空特征，即以在震前几天到几个月出现的中短期、短临前兆异常为主，短临异常尤为突出，空间分布范围较大。异常展布有一定规律性，并与地震有较好的对应关系。 |
| 关 键 词： | 中强地震 地磁异常 前兆特征 |

| Abstract: | In this paper, the authors describe the geomagnetic precursory anomalies observed before the moderately strong earthquake in North China and analyse their characteristics of time process and spatial distribution. The results indicate that the mid term, short term and imminent anomalies of geomagnetic precursors occurred several days to several months before the earthquakes, and the distribution of precursory anomalies is of a certain regularity and shows a certain corresponding relation with the earthquake occurrence. |
| Keywords: | Moderately strong earthquake Geomagnetic anomaly Precursory characteristics |
