摘要
2008年5月12日汶川8.0级特大地震,是继1976年唐山大地震后的又一人间悲剧。灾难过后,痛定思痛,如何保证在非常时期将地震数据可靠地传输回台网管理中心,为研究人员提供完整的数据波形,是地震观测技术人员在这次地震后应该慎重思考的问题之一。本文收集比较了中国地震部门常用的4种地震数据传输方式在8.0级特大地震中的表现,供同行参考。
A magnitude 8.0 earthquake happened on May 12, 2008 was another tragedy of human beings since 1976 Tangshan earthquake. After the disaster, as we recall the painful experience, we found one thing that should pay great attention to is how to transform the data of the earthquake back to the administration centre of networks for providing investigators with the complete waveform data. The performances of four transmission methods, which are common used in the departments of earthquake in China, in the magnitude 8.0 earthquake are compared in this paper. The result can be useful for the reference of the same occupation.
