摘要
1998年1月10日张北发生MS6.2级地震。在震前一、二年,远在400km外的邯郸地区的多种前兆手段准同步地出现了中期异常变化,这些异常的变化幅度显著,在时间上与张北地震有较好的对应关系,信度较高。分析邯郸地区的前兆异常与张北地震的关系,有利于该区强震监测预报水平的提高,也可为地震前兆特征和机理的深入研究提供实际依据。
On January 10, 1998, An Ms6.2 earthquake occurred in Zhangbei of Hebei Province. One to two years before the event, 400 kilometers from the epicenter, a lot of precursory approaches in Handan area showed medium term anomalies synchronously. As the variation of these anomalies is notable, and corresponds well with the event in time, their reliability is relatively high. It is helpful to analyze the relations between these anomalies and the earthquake, which may present some basis for further study of the characteristics and mechanism of earthquake precursors.
