An earthquake observation system installed by the Japan Meteorological Agency on the seafloor off the coast of the Tokai region has failed, raising concerns about the impact of delays in issuing emergency earthquake warnings. rice field.

It means that there is no prospect of recovery.

According to the Japan Meteorological Agency, an observation system that integrates seismometers and water pressure gauges installed on the seabed offshore from Shizuoka Prefecture to Mie Prefecture has been out of order since the 16th of this month, making it impossible to receive all data. I'm here.



After investigating the cause, it was found that there was a high possibility that the submarine cable for supplying power and transmitting data was damaged approximately 4 km off the coast of Omaezaki, Shizuoka Prefecture.



The cause of the damage is unknown, and we are planning to take steps to restore it in the future, but there is no concrete prospect.



For this reason, data will continue to be unavailable for the time being, and if an earthquake occurs near the observation point, the announcement of an earthquake early warning will be delayed by up to 13 seconds, and information on tsunamis observed offshore may not be released in some areas. It means it may disappear.



There will be no impact on issuing tsunami warnings and earthquake information.



The Japan Meteorological Agency said, "We recognize that it is an important system for detecting seismic activity in the Nankai Trough, so we would like to proceed with preparations for early restoration."
