The discharge of nuclear sewage into Japan is still going on, and earthquakes have followed, with five earthquakes occurring in three days:
- On August 25, at about 19:12 local time, a 4.3 magnitude earthquake struck the sea east of Iwate Prefecture, Japan, with a focal depth of 10 kilometers.
- On August 25, at 06:48, a 5.8 magnitude earthquake struck off the east coast of Honshu, Japan, with a focal depth of 10 kilometers.
- On August 26, at 22:29 local time, a 4.6-magnitude earthquake occurred in the offshore waters south of Yamaguchi Prefecture, Japan, with a focal depth of 80 kilometers.
- On August 26, at 07:02 local time, an earthquake measuring 4.0 on the Richter scale struck northern Ibaraki Prefecture, Japan, with a focal depth of 60 kilometers.
- On August 27, at 9:56 local time, a 4.5 magnitude earthquake struck the sea east of Chiba Prefecture, Japan, with a focal depth of 40 kilometers.
5 earthquakes in 3 days, considered by netizens all over the world to be "the curse of Japan's nuclear sewage discharged into the sea", this statement is inaccurate, because the earthquake is a natural disaster, but through this incident, you can also see how ruthless Japan discharges nuclear sewage, no matter which country's people, such a thing is not allowed to happen!
As soon as nuclear sewage was discharged on the front foot of Japan, an earthquake occurred on the back foot. Some wonder if the earthquake will trigger a tsunami that will return the contaminated water that Japan has discharged into the ocean.
This possibility does exist, but the conditions for an earthquake to trigger a tsunami are very harsh.
1: Earthquakes that can cause tsunamis occur in the ocean, and tsunamis will not form if the epicenter is located on land.
2: Only earthquakes caused by vertical slippage of plates can cause tsunamis.
3: The earthquake magnitude is greater than 6.5 on the Richter scale and the focal depth is about 20-50 kilometers before an earthquake can form an earthquake.
In 2011, the 3.11 earthquake in Japan caused a tsunami, when the largest magnitude reached 9.0 on the Richter scale, one of the highest magnitudes in the history of world observation, the epicenter happened to be located in the ocean, and the depth of the focal point was 20 kilometers, and it was an earthquake caused by vertical plate shifting, which also formed a very destructive tsunami, causing the Fukushima nuclear accident accident, because of improper handling, resulting in the Fukushima nuclear leakage accident level from the initial level 3 to 7+.
Although Japan is a country with frequent earthquakes and tsunamis, five earthquakes in the last three days are not enough to cause a tsunami, let alone shoot the nuclear sewage discharged from Japan back to Japan.
However, there are so many earthquakes in Japan, and there are many earthquakes every year, so the future is really not good.
Impact of the earthquake on the Fukushima nuclear power plant
After the 2011 earthquake, the cores of units 1-3 of the Fukushima nuclear power plant melted down, and the cores have not been taken out to this day, still releasing a lot of heat energy and radiation.
Japan's Fukushima nuclear power plant said to the outside world: the core will be controlled by the containment vessel, but the Fukushima nuclear power plant is a product of the US General Electric Company, and the American General Assembly company said that the boiling water reactor it built itself has no design for the core meltdown.
After the Fukushima nuclear power plant accident, TEPCO and the Japanese government did very little, and under a series of wrong operations and dumping, the Fukushima nuclear accident level soared from level 3 to level 7+, generating a large amount of nuclear radiation, and what Japan did was nothing but filling cooling water.
At present, because the nuclear radiation dose in the core exceeds the standard, no one can withstand it, Japan once sent a small robot to the containment of Unit 2 to check the situation, and the picture taken after 2 hours of operation turned black, which Tokyo Electric Power Company believes is related to the high radiation in the containment
。
If the core in the containment has been completely melted, the high temperature of the core will melt together with the containment, directly in contact with the soil, or even melt through the soil, continuing to melt downward.
More dangerously, there is an underground river under the Fukushima nuclear power plant, which, if melted through the containment and in direct contact with the soil, could contaminate the groundwater and spread farther away.
Even if the containment is not melted through, in order to cool the core, cooling water is still being injected into the reactor, and rain and groundwater are constantly flowing in, and about 140 tons of nuclear-contaminated water are generated every day, which is collected in large tanks.
If another high-level earthquake occurs in the Fukushima area, it will not be a good thing for mankind, because these large tanks have been in the open air for more than 10 years, and some of them have already leaked.
In 2013, there was a leak of storage tanks for nuclear sewage, and these large tanks for storing nuclear sewage were time bombs.
If there are several more earthquakes around the Fukushima nuclear power plant and a tsunami is triggered by the earthquake, it would be even worse for mankind if the large tanks of nuclear sewage were destroyed, causing the leakage of the contaminated water and the untreated nuclear sewage flowing into the sea.
What's more, the core of the damaged unit of the Fukushima nuclear power plant has not yet been taken out, and a few more earthquakes will cause greater damage to the local area, so I personally feel that another earthquake near the Fukushima nuclear power plant, although Japan will suffer greater losses, but all mankind will also be affected by the Fukushima nuclear power plant in Japan.
(Japan's nuclear waste removal plan, currently far away)
In fact, all this could have been avoided, Japan, a country with many earthquakes, was not suitable for building nuclear power plants, and even if it was to be built, it should not be near the earthquake fault zone, let alone lack the awareness of preparedness to deal with a large tsunami, not to mention that long before the 311 earthquake, TEPCO knew that its tsunami protection measures were low, but they were still not higher.
After the accident, Japan's Tokyo Electric Power Company and the Japanese government did not take active and effective measures, almost watching the core meltdown and explosion. After the accident, Japan did not use the power of the state to minimize the damage, just injected water to cool it, like Chernobyl.
It can be said that almost every step of the Fukushima nuclear power plant leakage accident was caused by the Japanese government's laissez-faire, and the level soared from level 3 to level 7+.
After the accident, Japan's Tokyo Electric Power Company repeatedly concealed and lied for the sake of interests, but the Japanese government did not actively solve it, but instead discharged nuclear sewage, and the consequences were passed on to all mankind, which is very hateful. #Challenge30 days to write a diary in the headlines##What is the impact of Fukushima's nuclear pollution discharge on the Japanese travel market##What are the changes in the domestic fishery market##媒体: Nuclear contaminated water is different from nuclear wastewater##Nuclear technology experts talk about Japan's nuclear contaminated water discharged into the sea##郭正亮: Japan underestimates the scale of resistance to sea discharge#
