As a terrible natural disaster, the power of tsunami need not be said. The wavelength of tsunami waves can reach hundreds of kilometers, and the propagation speed in seawater can exceed 700 kilometers per hour at will. After the tsunami wave reaches the coast, the water wall can reach tens of meters high. 1960 The tsunami triggered by Chile's earthquake of magnitude 9 swept across the Pacific Ocean from South America, and set off a huge wave of more than 10 meters off the coast of Japan more than 10,000 kilometers away, causing hundreds of deaths.
At present, the largest nuclear submarine manufactured by human beings is the typhoon class of the Soviet Union, with a displacement of only 26,500 tons. Under the impact of the tsunami with hundreds of millions of tons of seawater, whether you are a steel shell or a titanium alloy shell, it is just a drop in the ocean. If you really want to face the tsunami hard steel, the final result is likely to be shattered and ugly. What will happen to the nuclear submarine if it is not hard steel?
First of all, we need to know the cause of the tsunami. Tsunamis are mainly divided into three causes: volcano, landslide and earthquake, and large-scale tsunamis are generally caused by submarine earthquakes. There are two types of earthquakes and tsunamis. One is the uplift type. Due to the uplift of the seabed crust caused by the earthquake, the seawater in this area flows and quickly spreads to lower places, thus forming tsunami waves. The other is the descending type, because the earthquake causes the seabed crust to sink, and the sea level in this area becomes relatively low, and the surrounding seawater will flow backwards. When these flooded seawater hit the seabed, they rolled and collided to form tsunami waves. Whether it is rising or falling, the seawater at the source moves very violently. If the nuclear submarine is in this area, it is likely to be tossed up and down by the sea, and there is basically no possibility of survival.
When the tsunami wave reaches the offshore, it will show the most horrible appearance. Due to the sharp drop of seawater depth and the blocking of the coast, the waves caused by tsunami waves will increase geometrically on the continental shelf and offshore areas, from a few meters to dozens of meters in an instant. This kind of water wall can go deep into the inland for dozens of kilometers, and trees and buildings along the way will be swept away. If a nuclear submarine encounters a tsunami offshore, the most likely outcome will be washed up on a hill, and whether the people inside can survive can only be built.
