In 2020, the spread of the virus and the frequent occurrence of large-scale natural disasters have dealt a heavy blow to countries around the world. As of July 30, Japan's single-day new cases were 1,299, surpassing yesterday's 35 cases, setting a new single-day high.
This year, Japan's Hokkaido and Fukushima areas have successively experienced 4.5 and 5.5 magnitude earthquakes, but I did not expect that 7.0 magnitude earthquakes occurred in the waters of the Kuril Islands that night, and this is the second highest earthquake in the world this year, and then another 6.0 magnitude earthquake occurred in the waters near Kyushu Island on May 3, and even some Chinese coastal netizens said that they felt the earthquake at home. In addition to these two relatively large earthquakes, earthquakes below magnitude 6.0 also occur from time to time.
According to Japanese experts, frequent large-scale earthquakes are likely to lead to earthquakes in the South China Sea Trench and super South China Sea earthquakes, and once a super earthquake occurs, the whole of Asia will be affected. As we all know, Japan is a country with frequent earthquakes, with an average of more than 1,000 times a year.
Because the earth's crust is not a complete plate, and the trajectory between the plates is inconsistent, so collisions often occur, so countries where the plates collide often have earthquakes, to know that more than 90% of the world's earthquakes are from the Pacific Rim seismic belt, Indonesia seismic belt and ocean ridge seismic belt, and the Pacific Rim seismic belt is one of the most prone to high-magnitude earthquakes in the three seismic zones, and Japan is at the junction of the Eurasian plate and the Pacific plate, It is a small island country in the Pacific Rim seismic belt, which is why earthquakes occur frequently in Japan.
As early as December 21, 1946, the Nankai earthquake occurred in Japan, which was an earthquake measuring 8 on the Richter scale, and the tsunami caused by the earthquake was 4-6 meters high, causing 15 kilometers of farmland near Kochi Prefecture to sink to the bottom of the sea. And in 2012, earthquake experts from the Japanese Cabinet Office predicted that the largest earthquake in the South China Sea Trench may cause a tsunami of 34.4 meters, which can flood ten-story buildings, knowing that the South China Sea is sandwiched between several seismic zones, once an earthquake occurs, it may cause a tsunami, and the surrounding Pacific Rim seismic zone and the Himalayan earthquake zone near the multi-seismic area of the earthquake will also affect the South China Sea, which is why Japanese experts say that Japan's too frequent earthquakes this year may cause super earthquakes.
In a country like Japan with many earthquakes, the houses built are built in strict accordance with seismic defense standards, but Japanese experts believe that Japan's geology may have changed significantly, coupled with the frequent earthquakes this year and the impact of the Philippine plate movement, so experts believe that the probability of triggering an earthquake in the South China Sea is very large, and at present, Japan has begun to prepare countermeasures to avoid greater losses.
