| 摘 要： | 华北北部地区３次强震的交兆场研究结果表明，在地震发生前几个至十几（或几十个）个月的时间尺度上，未来震中区表现为前兆平静或空白的特征，同期外转眍中小地震活动十分活跃，地震前兆异常也大量涌现。根据这些现象，提出了地震中短期前兆场的震中区前兆空区模式。

| Abstract: | The
precursor fields before three strong earthquakes in the north of North China area are
studied.The results indicate that the precursors in future epicenters are quite or blank
during the time several,ten or tens of months before the earthquakes.Meantime
moderate-small seismic activities are very active in the outside areas,and also great many
seismic precursor anomalies appear.On the basis of them,a model of epicentral precursor
gap of seismic precursor field at middle-short term is proposed. |
