摘要: 1999年 11月 29日辽宁岫岩发生 MS 5. 4地震, 此震前后 ,在距其 600 km 且有渤海相隔的天津地区 ,一些前兆观测显示出中短期和临震的异常变化 ,对此 ,结合华北北部前兆异常的时、空特征及其与地震条带网络关系的分析 ,就地震条带网络对渤海周围地区前兆异常的发生及分布的控制作用进行了研讨。

Abstract: The earthquake with MS 5. 4 occurred on Novembes 29, 1999 in Xiuyan, Liaoning province. Before and after it, some precursory observations at Tianjin area, 500 km far from Xiuyan show the anomaly variation in the medium- and short -term and impending stages. This paper studied the controlling action of seismic band network over precursory anomalies occurred and distributed around the BohaiSea, combining the space- time characteristics of precursory anomalies in northern North China with the correlation between the space-time characteristics and seismic band network.

Key words: Far field precursory, Area around BohaiSea, Seismic band network, Controlling action
