本文概述了全球超长周期地震台网建成十年来的现状和发展;台网在衰减测量、超长周期震源机制和地球的非球面结构研究方面做出的贡献;还总结了运行的经验教训,并提出了未来的展望。本文对推动我国地球物理工作者进一步利用超长周期地震数据开展研究工作具有很好的参考价值。 This paper summarizes the status quo and development of the global ultra-long period seismic network in the ten years since it was established. It also contributes to the study of attenuation measurement, ultra-long period focal mechanism and the study of the earth’s aspheric structure. It also summarizes the experience and lessons of operation, And put forward the future prospect. This article has a good reference value to promote geophysical workers in China to further use of long-period seismic data to carry out research work.
