摘要
本文分析了宁波ZK—03井1979—1987年的水氡观测资料,发现该井水氡正常动态平稳,但在南黄海6.2级地震,舟山3.9级地震和台湾花莲7.6级地震前均有不同程度的负异常显示。文中还对异常形成的机理作了探讨。
By analysed the observational data (1979-1987) of radon in groundwater at the well of No. ZK-03 in Ningbo, it is found that the normal dynamic state of the radon in groundwater is stable, but before three earthquakes of M=6.2, M=3.9 and M=7.6 at the south of Yellow Sea, Zhoushan and at Hualian of Taiwan, there were different abnormal variation, by which the mechanism is analysed in this paper.
