Fear spreads over Japan's ”Nankai Trough Earthquake”... Earthquakes of magnitude 5.0 or higher occur every day

Concerns are growing over the possibility of a "Nankai Trough earthquake" in Japan. Anxiety is growing as a series of earthquakes of magnitude 5.0 or higher have been occurring every day.
The Korea Meteorological Administration reported that a magnitude 6.8 earthquake occurred at 12:29 p.m. on the 10th (Japan time) in the sea area 476 km north-northeast of Asahikawa City, Hokkaido.
The report cited the Japan Meteorological Agency and other sources. The epicenter was at 47.40 degrees north latitude and 145.60 degrees east longitude, with a depth of 490 km.
Prior to this, at around 8:01 pm on the 9th, a magnitude 5.0 earthquake occurred in Kanagawa Prefecture, which is in the Tokyo metropolitan area.
A magnitude 4 earthquake occurred in the western part of Kanagawa Prefecture. According to the Japan Meteorological Agency, the earthquake in the western part of Kanagawa Prefecture caused "
The quake was detected at a seismic intensity of 5. NHK reported that there was no risk of a tsunami from this earthquake. The seismic intensity, which is the earthquake scale of the Japan Meteorological Agency, is different from the magnitude, which indicates absolute strength.
It is a relative concept that expresses the degree of shaking of people in the area and surrounding objects with a number from 0 to 7. A seismic intensity of 5 is enough to frighten most people, causing dishes to fall off shelves and books to fall off bookshelves.
The Japanese media, citing experts, explained that the earthquake in Kanagawa Prefecture does not appear to be directly related to the "Nankai Trough earthquake."
The aftermath of a magnitude 7.1 earthquake that struck off the coast of Miyazaki Prefecture, Kyushu, Japan on the 8th continues.
Prime Minister Fumio Kishida was scheduled to visit Kazakhstan, Uzbekistan and Mongolia in succession for four days from the 9th to the 12th, and hold summit meetings in five Central Asian countries, but canceled his entire schedule.
The Japanese government is focusing on disaster response, such as assessing the damage caused by the earthquake and recovery efforts, as well as on building a system to prepare for the possibility of a further Nankai Trough earthquake, the possibility of which has been discussed.
The Nankai Trough earthquake is an earthquake that occurs at intervals of 100 to 200 years in the Nankai Trough, which runs from the coast of Shizuoka Prefecture in the western Tokyo metropolitan area to the sea area in southern Shikoku.
They estimate that a magnitude 8-9 Nankai Trough earthquake occurred in 1946, and that there is a 70-80% chance of it occurring within the next 30 years.
According to a 2013 analysis by the Japanese government, if a magnitude 9.1 earthquake were to occur, the area would spread from the Kanto region to Kyushu.
A tsunami of more than 10 metres is expected to reach the state, with up to 323,000 deaths expected, far exceeding those caused by the 2011 Great East Japan Earthquake.
