"The Great Nankai Earthquake will come no matter what." The Korean Peninsula's "direct impact" [Now News]

Korea, the next country, is also increasingly anxious about the 6.9-magnitude earthquake off the coast of Miyazaki Prefecture east of Kyushu, Japan.

A 6.9-magnitude earthquake was observed last night at 9:19 p.m. in Chubinada, the sea off Miyazaki Prefecture east of Kyushu, Japan, and a 7.1-magnitude earthquake occurred on August 8 last year in a similar area.

The Great Nankai Earthquake' refers to a huge earthquake in the Nankai Trench, which occurs when the Philippine version below the Philippine Sea digs under the Eurasian version of the Japanese archipelago.

Domestic experts also advise that if the Nankai earthquake occurs, it can record a maximum magnitude of 9, and the impact cannot be avoided by Korea, so preparations are needed.

When a 7.1 magnitude earthquake struck southern Kyushu in August last year, the Korean Peninsula was analyzed to have moved 1cm up and down.

If an earthquake with a magnitude of 9.0 occurs, the energy is 1,000 times larger than that of a magnitude 7.1 earthquake, and the degree of shaking of the ground is 30 times larger.

Therefore, if a 9.0-magnitude Nankai earthquake occurs, the Korean Peninsula is expected to move 30cm up and down.

The 2011 Great East Japan Earthquake was 1,200 kilometers away, so the amplitude of the Korean land was not large, but experts say that if the Great Nankai Earthquake, which is relatively close to the Korean Peninsula, it will not be known how big the aftermath will be.

Hong Tae-kyung, a professor of earth systems at Yonsei University, said, "It is certain that a major earthquake will come within 30 years, but no one knows if it will be a minute later or 30 years later," and stressed, "A different shock could come to the Korean Peninsula."
