摘要

苏家屯观测台是位于辽宁沈阳的一个地方性专业地震观测台站,用EMAOSL数字化电磁辐射观测仪进行电磁观测。本文将该台站4年多的电磁辐射观测资料和这期间观测到的MS4.0以上的震例进行了收集和整理,从观测仪器的性能指标、地质构造特征、电磁信息的来源等方面进行了震例的电磁前兆异常特征分析。研究认为,该台站前兆异常突出,电、磁异常同步性好,异常信息与发生在上地壳的震源深度小于20km的地震具有良好的对应性,同时,对震级较大的地震,其前兆异常有日变周期特性。
The Sujiatun observation station is a local professional seismic observation station in the city of Shenyang, Liaoning Province. Electromagnetic radiations observation apparatus, with the type of EMAOS-L, are used there.Four year's observation data and observed earthquakes with M _S≥4.0, are collected in the Sujiatun observation station. The characteristics of electromagnetic radiations abnormities and earthquakes are analyzed from such aspects as capabilities of the apparatus used, tectonic structure, origins of electromagnetic radiations and so on. By analysis, for this observation station, precursor abnormities are remarkable. The electric and magnetic abnormities are with good synchronism and the abnormities can respond better to the earthquakes with the epicenter being less than 20km and taking place in upper-lithosphere. At the same time, for earthquakes with large magnitudes, the precursor abnormities have daily periodicity.
