On March 11, 2011, a magnitude 9.0 earthquake broke out in northeastern Japan, which killed 15,000 people, disappeared more than 3,000 people, and displaced 340,000 people, setting a record for the heaviest casualties and the worst economic losses in Japan's history!
Earthquakes often break out in Japan, and apart from the high earthquake scale, what other reasons have caused Japan to suffer heavy losses?
Japan has been hit by earthquakes, and the 311 earthquakes lack prevention
The Japanese archipelago is located at the junction of the Eurasian and Pacific plates, at the edge of the Pacific Rim seismic belt. Perennial crustal movements have caused one-tenth of the world's volcanoes to congregate in Japan, and have also brought countless earthquakes.
According to statistics, japan averages more than 1,000 earthquakes of magnitude 3 or above every year, so Japan attaches great importance to earthquake prevention. In order to enhance the earthquake resistance, Japan has made a lot of efforts in the construction structure of the house, which makes Japan's earthquake resistance leading the world.
At 9:00 a.m. on March 9, 2011, a 7.2-magnitude earthquake broke out in the Tohoku region of Japan, and the Japan Meteorological Agency immediately issued an earthquake warning, due to full experience and advance preparation, the earthquake did not cause much damage, and people's lives gradually returned to calm.
On the morning of March 11, the Japan Meteorological Agency received a report from seismic instruments that a magnitude 7 earthquake would be coming. Due to the 7.2 magnitude earthquake that had just erupted, the staff judged that the seismic instrument was malfunctioning and did not issue an earthquake warning.
At 2:46 p.m. on March 11, in the Kanto region of Tohoku and Tokyo, just as people were working as usual, the earth began to shake, the houses swayed, the computers and vases on the desks fell, and the decorations on the ceiling fell to the ground.
Although the strong earthquake lasted only 6 minutes, the Japanese island of Honshu moved and the earth's crust shifted. In this earthquake, the earthquake in Miyagi Prefecture, Fukushima Prefecture, Ibaraki Prefecture, and Tochigi Prefecture in Japan all had earthquake magnitudes above 6.
The earthquake was mainly caused by the convergence at the junction of the plates, causing a violent impact. In japan's northeastern coastal region, the end of the magnitude 9.0 earthquake was accompanied by a steady stream of aftershocks. Among them, the first moment zero aftershock level reached 7.1 magnitude, and then more than 40 moment zero aftershocks between 5.0 and 7.0 erupted.
The damage caused by the earthquake was mainly concentrated in miyagi, Fukushima, and Iwate prefectures, causing more than 15,000 deaths and more than 2,000 missing. This time the magnitude of the earthquake reached 9.0, creating the first earthquake in mainland Japan to exceed 9.
Due to Japan's lack of preparation and the high magnitude of the earthquake, the earthquake caused a serious blow to the three prefectures in northeastern Japan, the local houses were seriously damaged, and the whole country of Japan was tired of coping with post-earthquake reconstruction.
Often after a major earthquake, a tsunami occurs, and Japan's earthquake rating has set a record for the mainland, how does Japan cope with the upcoming tsunami?
The tsunami was unexpected, and Japan's economy suffered heavy losses
Japan has already learned the news before the tsunami, why have the northeastern coastal counties not been spared, and nearly 80% of the area has been submerged?
After the earthquake broke out, the Japan Meteorological Agency has issued a warning to the three hard-hit prefectures in the northeast that a tsunami on the Pacific coast is coming. Tsunami warnings were issued from Hokkaido to the Izu Islands.
However, the Japan Meteorological Agency's estimate of the tsunami is seriously insufficient, and according to the post-disaster Japanese news report, the height of the tsunami is at least 23 meters, which is several times the tsunami warning.
Alerted by the Japan Meteorological Agency for a tsunami, residents of the three tohoku prefectures did not care because they were on the coast, and they were already surprised by the tsunami, and in addition, there was no large-scale tsunami, and Fukushima, Miyagi, and Ibaraki prefectures were not fully prepared for the arrival of the tsunami.
When a major earthquake broke out in northeastern Japan, the Pacific Tsunami Warning Center in Hawaii immediately issued warnings to Japan, the Mariana Islands, and Russia. This shows the severity of the tsunami at that time.
Although Japan already knew that a tsunami was coming, the severity of the tsunami was unexpected.
The tsunami hit Honshu Island, Hokkaido Island, Kyushu Island, and Shikoku Island on the Pacific coast side of the pacific coast, covering a total of 2,000 kilometers of coastline. After the three northeastern counties were hit by earthquakes and tsunamis, the coastal areas suffered devastating blows.
Miyagi Prefecture, the most populous of the three northeastern prefectures, has not been spared many cities in the prefecture. Sendai City was hit by a severe tsunami that caused severe flooding and local residents fled. The 100-kilometer coastal area of Fukushima Prefecture was covered by a tsunami-induced mudslide.
At the Matsuyama base of the Japan Air Self-Defense Force in Higashimatsu City, Miyagi Prefecture, 18 fighter jets were flooded and malfunctioned, and more than 200 people inside the base were missing.
The city of Rikuzen-Takata was destroyed by the tsunami. More than 80 percent of the city was covered by floodwaters, and more than 3,000 homes were washed away. A day later, more than 400 bodies had been found. Under the floods, the Japanese Fire Agency was paralyzed and could no longer contact local survivors.
Within 6 kilometers inland from the bay, countless fishing boats and houses were destroyed, and more than one-third of the city was submerged. Fishing boats were even on fire in several places as they rolled down the oil tanks. In the city of Yachinobu in Aomori Prefecture, countless cars were swept away by the flood, countless people disappeared, and most of the area was flooded.
Prefectures in Japan's Tohoku region were badly damaged, but other areas were also restless. At an oil refinery in Chiba Prefecture, several oil storage tanks inside ignited a fire, and other equipment was burned, which immediately triggered an explosion, and the resulting fireball rose tens of meters into the sky.
Dozens of fires broke out in the Tokyo area due to the earthquake, the top antenna of the Tokyo Tower was tilted by the earthquake, and Tokyo Disneyland announced its closure. The ceilings of some taverns fell, and a school in Tokyo that was undergoing a graduation ceremony suffered 36 casualties.
Tokyo's subway and rail transit systems were paralyzed, and a large number of residents stayed in makeshift tents, and the crowds were crowded for a while. The city of Hakodate, Hokkaido, was hit by a tsunami more than two meters high, and one of the men was killed because he was too drunk to hide before the tsunami struck.
This massive tsunami was linked to crustal movements and may have been linked to stresses released from trenches 200 kilometers away on the Makika Peninsula in Miyagi Prefecture, Japan. The Pacific plate near the trench was squeezed in the northwest and southeast directions before the earthquake and became stretched.
After the successive shocks of earthquakes and tsunamis, Japan has been unable to ensure safety at Fukushima's first nuclear power station, so how should Japan deal with this headache?
Fukushima nuclear power plant leaked, a large amount of nuclear radiation nuclear pollution
How can Japan take care of the fukushima nuclear power plant leak, the 30-kilometer area around it was banned, and more than 50,000 people were evacuated?
When the earthquake broke out on March 11, Fukushima Daiichi Nuclear Power Plant Units 1 to 3 were in normal operation, and aircraft 4 to 6 were under regular inspection. The earthquake was followed by a tsunami that caused the plant to lose its power supply. However, there were diesel generators at that time, and the Fukushima nuclear power plant was already in operation.
Fifty minutes after the earthquake erupted, a 14-meter-to-15-meter-high tsunami slammed into Fukushima, and the diesel generator set up in the basement was flooded and the plant lost its power source.
Without electricity, the pump cannot operate, and it is difficult to continue to inject cooling water into the reactor core and the nuclear reaction, and it is difficult to remove the heat generated by the nuclear reactor. The nuclear fuel began to heat up continuously, melting and penetrating the facilities of the power plant.
On March 14, Fukushima Nuclear Power Plant Units 1, 3 and 4 exploded, causing serious damage around the plant. Throughout the accident, a large amount of radioactive material was leaked around.
On March 15, Aircraft 2 was damaged by a control device, causing an explosion. Immediately, Japan organized the evacuation of residents 20 kilometers around the factory. Subsequently, Japan issued a 30-kilometer airspace around the nuclear power plant as a no-fly zone.
On March 16, the No. 4 unit of the nuclear power plant exploded again, and Japan upgraded the degree of nuclear accident to level 5. On March 20, Japan publicly stated that the nuclear power plant damaged in the earthquake would no longer be used.
After the Fukushima nuclear power plant leak, Japan informed the International Atomic Energy Association on March 12 that it was seeking international support. Subsequently, the Japanese emperor came forward to comfort the residents of the nuclear accident disaster area, and Japan issued loans to the Tokyo Electric Power Company through financial institutions.
When China learned of the situation, out of the spirit of internationalism, it immediately organized personnel to go to the rescue.
In the AFC Champions League final in South Korea on September 27, South Korea's Jeonbuk Hyundai team played against Sakura Osaka, Japan. During the match, Korean fans wrote posters in Japanese that read "Celebrating the Great Earthquake in Japan", which made the Japanese team angry.
During the Fukushima nuclear power plant, due to poor communication between Japan and the local people, it did not take active measures, resulting in the failure to effectively control the nuclear accident, and the problem of nuclear pollution became more and more serious. A few years after the nuclear accident, Japan was indifferent to the affected residents and went so far as to stop subsidizing them and urging them to return to their hometowns.
Due to the indifference of the Japanese people, the Fukushima nuclear leaks were as discriminated against as the residents of Hiroshima and Nagasaki.
Later, Japan's environment minister said tens of thousands of tons of nuclear wastewater from Fukushima might have to be dumped into the Pacific Ocean. As soon as Japan opened its mouth, the idea of a stone immediately drew a scolding from the international community, and the idea of dumping nuclear wastewater into the Pacific Ocean was strongly opposed by Japan's domestic fisheries and South Korea. Despite opposition from many countries, Japan dumped nuclear wastewater into the Pacific Ocean.
Eight years after the 3.11 earthquake, the Japanese Police Agency released data showing that the death toll in Fukushima, Miyagi, and Iwate prefectures alone was as high as 15,897 and 2,533 were missing. As a result of the Fukushima nuclear accident, more than 50,000 people are still in the evacuation life as of 2019.
Japan committed many crimes in World War II, and the "3.11" earthquake became the most difficult day for Japan after World War II, and Japan's emergency organization capacity was insufficient, which was an important reason why Japan suffered "heavenly punishment" this time.
