1998年开始的“海洋半球观测研究计划”,目前正实施着极东和西太平洋地区的宽频带地震观测、GPS观测、电磁观测和超导重力观测 ,以及深海底宽频带地震观测和使用海底电缆的电位观测。为了有效利用这些观测资料特成立了“数据中心”,并于 1998年 4月开始运行。现在已经能够利用 The “Ocean Hemisphere Observational Research Project” started in 1998 is currently implementing broadband seismic observations, GPS observations, electromagnetic observations and superconducting gravity observations in the eastern and western Pacific, as well as deep-sea broadband seismic observations and the use of submarine cables Potential observation. In order to make effective use of these observations, a “data center” was established and started operation in April 1998. It is now available
