As 2024 arrives, people are in the midst of a happy hour when a major earthquake struck near Japan.
At 15:10 Beijing time, a large earthquake of about 7.4 magnitude occurred in the Noto area of Japan, and the magnitude of the earthquake was confirmed by experts to be 7.6, and there were many concurrent disasters and great danger.
Pacific Rim Seismic Zone
Japan is an island country located in the Pacific Rim Seismic Zone, and geological disasters are frequent, but the earthquake with a magnitude of 7.6 was the strongest earthquake that Japan has not observed since 2018.
According to the analysis of experts, this earthquake belongs to the earthquake group type, that is, a large-scale earthquake in the group, and the possibility of a larger earthquake in the future cannot be ruled out.
As for Japan, after learning about the type of earthquake, it began to start a nationwide warning at the first moment after the earthquake occurred.
An earthquake is the movement and release of underground energy, while a group earthquake has no mainshock, so the underground energy will not be released at one time, and in the subsequent time, there will be continuous strong earthquakes in its area.
In less than half an hour, three major earthquakes of magnitude 5.7, 7.6, and 6.1 struck the Noto area of Ishikawa Prefecture, and there was a lot of attention around the world.
The earthquake spread over a wide area, with a magnitude 7 earthquake followed by a moderate earthquake, and the number of times that the number of subsequent aftershocks in the Kumaden area was felt 49 times in four hours.
As of 1 o'clock the next day, 93 aftershocks were observable across Japan, all with a magnitude of 1 or higher, and another magnitude 5.6 earthquake struck the Kumato area the next morning and a magnitude 4 earthquake in the afternoon.
Due to the frequent occurrence of earthquakes of moderate intensity, the number of people killed in Japan has reached 48 as of the afternoon of January 2, and the number continues to increase.
At the same time, due to the mass occurrence of earthquake disasters, a series of disasters occurred on the Japanese islands, including but not limited to volcanoes, tsunamis, and overflow of cooling water from nuclear power plants.
水火灾害袭来
In the face of the vastness of nature, we can't help but feel the weakness of human beings. At the beginning of the new year, Japan begins to face the severe test of nature.
In addition to the mass earthquakes, the Mt. Ontake volcano in Kagoshima Prefecture, Japan, also suddenly began to erupt, and it cannot be ruled out that it was affected by the earthquake, and it is not clear whether it is an isolated case.
Around 2022, there will be frequent news of possible eruptions of Japanese volcanoes, and Japan may have expected the occurrence of geological disasters, because many volcanoes in Japan have long been active, but what they did not expect was that earthquakes and volcanoes and tsunamis came together.
Since 2018, the frequency of earthquakes of magnitude 7 or higher has been decreasing in Japan, and last year there were two earthquakes of magnitude 6 or higher in the Kumaden area, which has aroused the thinking and discussion of many geologists.
At the time, it was estimated that the amount of energy generated from Japan's underground was so large that it was estimated that it could trigger the eruption of volcanic groups.
Judging by this data, the energy in the Japanese underground is far from being poured out, and the Japanese authorities are also nervous after seeing the 1,600-meter-high smoke column in Kagoshima.
In addition to reassuring the existing disaster, they also need to continue to be vigilant in the coming week to prevent possible follow-up disasters, the current estimate is several earthquakes of about 7 magnitude, and other volcanic eruptions cannot be ruled out.
After the earthquake, a tsunami more than 5 meters high appeared around Japan, which continued to impact the coastal areas, and due to the continuous aftershocks, the Japan Meteorological Agency also specially reminded coastal and riverside residents to be careful of repeated tsunami attacks.
The crisis of nuclear power leakage
For neighboring countries, the issue of nuclear leakage is the most concerning.
Prior to this, the Fukushima nuclear accident in Japan had continued to have an impact, and in order to solve the problem of sewage caused by the nuclear crisis, the Japanese government has begun to defend its own interests but harm the world in the face of global condemnation.
Fish in the waters around Japan have been dying since the discharge of nuclear sewage into the ocean, and many countries around the world have begun to boycott seafood in Japan's waters due to Japan's illegal discharge.
In Japan's current public announcements, the Kashiwazaki Kariba Nuclear Power Plant has become the most concerned existence of the public.
Even though the Japanese side said that the water in the fuel pool only overflowed due to the shaking of the earthquake and did not flow outside the building, so it would not affect the outside world, the public is still skeptical about the news because the Japanese government often chooses to hide the facts about related incidents.
Since then, the transformer of another nuclear power plant in Japan has also caught fire due to the earthquake, which has now been extinguished, but considering that there are already two nuclear power plants due to the earthquake problem, the rest of the world is urging the Japanese government to strengthen the management of its own nuclear power plants, after all, there may be greater geological hazards in the future, to avoid large-scale nuclear pollution due to negligence and slackness.
After all, disasters are not unpredictable, nor can they be resisted, for ordinary people, we must pay attention to the Xi of earthquake knowledge, and when danger occurs, we have more strength to protect ourselves.
