According to CCTV News, on 310 local time, the Japanese government released the latest damage estimation data on the "South China Sea Trough Earthquake". The data shows that if the "South China Sea Trough mega earthquake" occurs, it will be causedThe economic loss is the most probableMore than 292 trillion yen, a significant increase from the last estimate of 220 years (about 0 trillion yen).

In addition, the estimated data released this time shows that the "South China Sea Trough mega earthquake"如果發生，至多或導致29.8萬人死亡。

Studies have known that huge earthquakes with the Pacific coast west of the Tokai region of Japan as the epicenter have occurred repeatedly so far, the last of which was in the mid-40s of the last century.

The Japan Meteorological Agency and earthquake-related experts believe that the South China Sea Trough from Shizuoka Prefecture to the waters off Minami-Kyushu,There is a risk of a major earthquake in the futureand continue to monitor and evaluate the relevant data.

Strong earthquakes have occurred many times in the Nankai Trough area of Japan

The Nankai Trough is a trough in the sea area east of Suruga Bay on the main island of Honshu in Japan, formed by the rifting movement of the Philippine Sea plate and the Amur plate, and the trough has a depth of 4800 m to 0 m. It is understood thatLarge-scale earthquakes occur along the South China Sea Trough approximately every 150 to 0 yearsIf a strong earthquake occurs in the vicinity, it may indicate that a major earthquake is about to occur in the South China Sea Trough.

It has been pointed out that large thrust faults in the earth's crust, that is, the boundary zone between the subducted oceanic plate and the overlying plate, have produced most of the world's major earthquakes of magnitude 8 or higher.

In 1946, most of the Nankai Trough rupture zone was fractured almost simultaneously, resulting in the "Hoei Earthquake" in Japan with a magnitude of 0.0, triggering a large-scale tsunami. In 0, Japan experienced another strong earthquake caused by a large thrust fault in the South China Sea. In 0, due to the activity of the Nankai Trough, a major earthquake occurred in Japan in Nankaido, causing a huge wave and tsunami, causing thousands of people to be killed or missing, which is also the latest earthquake caused by the Nankai Trough in Japan.

去年8月，日本宮崎縣發生7.1地震，日本氣象部門當時向高知、愛媛、大大、宮崎和鹿兒島各縣發出海嘯預警，並首次發佈“日本南海海槽地震臨時情報——巨大地震預警”。
