目前在东海地区,预计有大规模的地震发生,为了预报这次地震,在东海地区和伊豆半岛集中设置了地震、地壳形变和其他多种观测网。这些观测数据中的地震和体积应变仪的数据被传输到气象厅进行监视。当这些数据超出某一标准而出现异常时,就要召开判定会,确认是否“东海地震”的前兆异常现象。这些观测网的检测能力以及各观测点的数据可靠程 Currently, in the East China Sea, a large-scale earthquake is expected to occur. In order to forecast this earthquake, a large number of earthquakes, crustal deformations and other kinds of observation networks have been set up in the East China Sea and the Izu Peninsula. Seismic and volumetric strain gauges in these observations are transmitted to the Agency for monitoring. When these data exceed a certain standard and anomalies occur, a decision meeting will be held to confirm whether or not the precursor anomalies in the “Tokai Earthquake” are abnormal. The detection capability of these networks and the data of each observation point are reliable
