摘要： 台湾海峡 7. 3级地震是 90年代地震活跃期在我国的一个标志地震。根据全国 81口水位观测井水震波资料,对其水位振荡、水位阶变、记震距离等方面作了分析。研究结果表明,本次地震显示水位振荡快衰减也快以及水位阶变多、幅度大和不存在最佳记震距离等主要特征。水震波蕴存着丰富的地球物理信息内涵,这对地震孕育、发生信息的提取有其意义。

Abstract: The Taiwan Strait earthquake with MS 7. 3 was a marker one in our country for 1990s′ seismically active period. According to the data of water-level earthquake wave obtained from 81 w ells in our country, we analysed earthquake water-level vibration, water-level step change and the observation distance and so on. The results indicate that the main characteristics of this earthquake w ere ex pressed as high frequency and fast attenuation of water-levelvibration, great range of water-level step change and without best observation distance and others. The water-level earthquake wav e is rich in geophysical information and has practical significance for ex traction of information regarding earthquake prepara-tion and occurrence.
