It is also reported that on December 12, local time, the Eight Household Space Base of the Maritime Self-Defense Force reported to the Coast Guard Headquarters of the Second Jurisdiction that a large number of fish carcasses were floating in the waters near dongtong village in Aomori Prefecture. Subsequently, eight coast guard patrol boats rushed to the scene and found a large number of small sardine-like carcasses floating on the surface of the sea, covering an area ranging from about 4 kilometers long and about 50 to 100 meters wide. The Coast Guard said there was no news of a ship accident near the area involved and it was unclear why the body appeared.
It should be noted that there have been frequent visions in Japan in recent days. Since the afternoon of December 4, local time, earthquakes have occurred in the coastal waters off the Tugala Archipelago in Kagoshima Prefecture, Japan, and as of now, more than 280 earthquakes with a magnitude of 1 or above have been observed in Japan. It is reported that during December, the coastal waters of the Tugalas were only affected by a magnitude 1 on December 1, which was "slightly earthquake-inducing". There were 9 earthquakes with a magnitude of 3 that "most people feel". Since December 3, there have been consecutive earthquakes with a magnitude of less than 5, and the magnitude of the earthquake is "frightening to most people."
The local meteorological department has called for attention to earthquakes with a standard magnitude of 5 or higher in Japan in the coming weeks. In this regard, some media believe that the local earthquake may cause a huge tsunami. Since the beginning of December, earthquakes have also occurred in Yamanashi Prefecture and Wakayama Prefecture. Wakayama and Kagoshima are both anticipated epicenters of the Great Nankai Trench earthquake, so it has been pointed out that frequent earthquakes may be precursors to the Nankai Trench earthquake.
It is reported that the 2020 report of the Japanese government's Earthquake Investigation Committee pointed out that the probability of the "South China Sea Trench Earthquake" in the next 30 years is as high as 70% to 80%, and the highest magnitude can reach 9.1 on the Richter scale. The Japan Central Conference on Disaster Prevention and Catalysis Seminar on Disaster Prevention Measures estimates that the number of dead and missing people caused by the tsunami caused by the Great South China Sea Trench earthquake will exceed 231,000. Not only that, but considering that the epicenter of the Yamanashi earthquake was only 30 to 40 kilometers away from Mount Fuji, there are also concerns that Mount Fuji is about to erupt.
In fact, the latest observational data show that the pressure inside Mt. Fuji has risen to a value close to the critical value of 1.6 megapascals, and there is a risk of eruption at any time. It has been 314 years since the last eruption on Mt. Fuji. The researchers expect that if Mt. Fuji were to erupt on the same scale as the last, the ash would cover the tokyo metropolitan area, including Tokyo. In addition to the possibility of large-scale casualties, the eruption will also bring huge economic losses to Japan as high as 2.5 trillion yen, or about 146.8 billion yuan.
At a time when Japan is facing multiple terrible crises, people have pointed out that the earth may have "big problems" in the intensification of crustal movement. On the afternoon of December 4, local time, the Semeru volcano in the eastern part of the Indonesian island of Java erupted violently. The number of deaths from the disaster continued to rise, reaching a total of 45 as of December 10, local time. In the 48 hours from the early morning of December 7 to December 9, local time, nearly 100 earthquakes occurred off the Oregon Coast of the United States, during which at least nine earthquakes of magnitude 5.0 to 5.8 occurred.
