Regarding the "Kuril Trench" and "Japan Trench" from off Hokkaido to off Iwate Prefecture, where it is said that a huge earthquake or tsunami is imminent, if an earthquake occurs in the assumed epicenter area, it will be a huge earthquake. It turned out that we will start to consider whether we can provide information that calls for the prior attention of.
The issue is how much concrete disaster prevention measures can be taken.
Along the "Kuril Trench" from the Kuril Islands to the offshore of Hokkaido and from the south of Hokkaido to the offshore of Iwate Prefecture in the "Japan Trench", the national government reviewed the assumptions of earthquakes and tsunamis, and an earthquake of the Great East Japan Earthquake class occurred. , Hokkaido and Tohoku are said to be flooded with tsunamis of 20 meters or more.
The national government is studying damage estimation and disaster prevention measures, but according to the people concerned, if any abnormality is found in the data such as earthquakes in the epicenter area of the "Kuril Trench" or "Japan Trench", it will be huge. It turned out that we will start to consider whether we can provide information that calls attention to the earthquake in advance.
It is expected that a new study group will be held by experts in the near future to discuss the content of the call.
There is "temporary information" that is announced when the epicenter area shifts by about half in the Nankai Trough as a mechanism to call attention to residents when an abnormal phenomenon is observed, but in the Chishima Trench etc. Since there is little knowledge about how to get up, the issue is how far we can connect to specific disaster prevention measures.
