摘要
廊坊地区所属的安头屯井、浅牛6井是静水位观测井,文安井由文安地震台进行多年的水氡观测。这3口井始测时间为20世纪80年代,资料连续可靠。资料清理过程中发现在1998年1月10日张北6.2级地震前以及强余震活动中均有明显的异常显示。本文探讨了张北震例的综合异常特征。
The observation in Antoutun well and Qianniu No.6 well located in Langfang region is static water level, The observation in Wenan well that has been carried out many years by Wenan Seismostation is water radon. The observation of the 3 wells started from 80s of last century, and their data is continuous and reliable. Through study we found that there were obvious anomalies before Zhangbei M6.2 earthquake occurred on Jan.10 of 1998 and its strong aftershocks. The synthetic characteristic of anomalies for the event is also discussed here.
