How did the tsunami happen in Japan?

A tsunami earthquake occurred as a result of an earthquake under the sea surface, which led to the movement of sediments and the release of a huge amount of energy from the earth's structural plates, as they slipped from their sudden stillness and rushed towards each other, and it must be noted that it occurred at a depth of 24.4 km, and about a hundred kilometers away. off the coast of Meiji, shifting the Earth's axis of rotation by about ten centimeters.

The Tohoku tsunami occurred in 2011 AD in Japan, with a magnitude of 8.9 on the Richter scale, as it struck the eastern coast of Japan, which moved many waves in the Pacific Ocean, knowing that the epicenter of the earthquake was located 373 km northeast of the capital in Tokyo, and 130 km east of Sendai. , which led to many deaths and the destruction of Sendai Airport in Japan, and a high rate of property losses, in addition to the destruction of the infrastructure in the nuclear and oil stations, and their stopping of work, and it also led to a rise in sea level to 10 meters as a result of the huge water coming from the Pacific Ocean, and the rising smoke In Tokyo, it must be noted that it was the most violent earthquake that occurred in the history of Japan since the start of documenting earthquakes 140 years ago, bearing in mind that the Honshu earthquake preceded this earthquake by two days, but it was of a magnitude of 7 on the Richter scale.

Nuclear explosions and radiation after the tsunami earthquake

On the morning after the earthquake, the Japanese government issued a warning of a meltdown in the Fukushima reactor, which was destroyed as a result of the earthquake, so an emergency was declared at the second nuclear plant, which increased fears of radioactive steam leakage from the Fukushima plant due to the high pressure in it, and the cooling systems were disrupted. And the electricity supply, so the Japanese Prime Minister Naoto decided to expand the evacuation operations around the station to a radius of 20 km, and the oil refineries were closed and later caught fire, and several fires occurred in the coastal region near Sendai, where the car and electronics factories were closed, and electricity was cut off from millions of homes and companies, Narita Airport in Tokyo was closed, and railway services and all ports were suspended.
