摘要

日本气象厅于2004年启动了一个项目，在东海和东南海地震的假定震源区域周围安装新的海底地震仪(OBS)。日本气象厅于1978年在恩树海东海地震假定震源区安装了海底地震仪，并持续进行地震观测;已启动的项目是在现有海底地震仪的西面安装新的海底地震仪。新OBS的目的是提高小地震的探测能力，并迅速发现大地震和精确确定其震级，以便进行地震早期预警。

JMA's new Ocean Bottom Seismographs (OBS) using marine cable installed at the Sea of Enshu to the Sea of Kumano

JMA started a project in 2004 to install new ocean bottom seismographs (OBS) using marine cable at around assumed focal regions of anticipated Tokai and Tonankai earthquakes. JMA installed ocean bottom seismographs (OBS) in 1978 at assumed focal region of Tokai earthquake at the sea of Enshu, and has been keeping seismic observation using them; the started project is to install new OBS on west of the existing OBS. The aim of new OBS is improvement of detection ability of small earthquakes, and also prompt detection of large earthquake and precise determination of its magnitude for early earthquake warning.
