摘要： 介绍五里营综合观测井1998年1月10日张北6. 2级地震的前兆异常及震时、震后效应。这次异常的主要特点是水温、水位二项异常几乎是同时出现、逆向发展,这种异常关系一直持续到张北地震震时才转变为同步、同向变化,为多年以来在地下流体综合观测资料中所少见。

Abstract: This paper presents the precursory anomaly of underground water temperature and the water level in Wuliying well before the Zhangbei-Shangyi earthquake, on January 10, 1998, and the co-effect and after-effect of the earthquake. The main characteristics are that the precursory anomaly of underground water temperature and level appeared at the same time and their trends were in reverse direction before the earthquake. After the earthquake the trends are changed into same direction. This phenomenon is unique in the underground fluid comprehensive observation.

Key words: Water temperature, Water level, Precursory anomaly, Zhangbei earthquake
