If a tsunami occurs on the coast, can a nuclear submarine hiding underwater escape?

Submarines, nuclear submarines, and aircraft carriers all represent mankind’s most advanced shipbuilding technology, and they also reflect our human wisdom. We all know that submarines are not only a weapon for military combat, but also one of the main tools for humans to explore the mysteries of the ocean. Compared with submarines (nuclear submarines) and ships traveling on the sea, the most obvious advantage of submarines is that they are very concealable. , can avoid typhoons, hurricanes and other natural disasters on the sea, but some friends have raised a question. Submarines can avoid typhoons by sinking, but can they avoid more powerful tsunamis? Let’s find out together below.

Actually, I think this question is quite interesting, because tsunami should be one of the most destructive natural disasters in nature. When it occurs, it can sweep across the coastal areas, submerging roads and houses along the way, etc. When a tsunami reaches the shore, the waves can reach a height of more than ten meters, and even ships docked at the dock will suffer. The destructive power of small tsunamis may be relatively small, but the destructive power of large tsunamis makes even aircraft carriers afraid. Therefore, aircraft carriers will always pay attention to the weather forecast when sailing. If they encounter a typhoon or a tsunami, they will usually take a detour. In this regard, some friends said that submarines are different from aircraft carriers. Submarines sail underwater. Even if there is a violent storm on the sea, the submarine can be safe and sound. However, the power of the tsunami is huge. Can the submarine escape?

Experts gave the answer: Whether a submarine can escape safely depends on its location and the size of the tsunami. Tsunamis are generated by submarine earthquakes. When an earthquake occurs on the seabed, the shock wave generated will Using seawater as the medium for propagation, if it is an earthquake below magnitude 7, the structure of most submarines can withstand the shock wave, so the submarine will be safe. But if it is a major earthquake of magnitude 7 or above, the shock wave it generates is very strong. If the submarine and the shock wave form a vertical force, then the submarine is likely to be severely damaged. In addition, submarine earthquakes of magnitude 7 or above cause Tsunamis are also very huge and can directly cause serious damage to a city, such as the famous Indonesian tsunami.

However, extremely large tsunamis rarely occur, and the power of tsunamis mainly occurs along the coast. If a submarine is floating on the sea surface or underwater when a tsunami occurs, it will generally not be affected, because diving The tonnage of a submarine is usually tens of thousands of tons, and even if there are waves on the sea, it will not cause damage to the submarine. But if the submarine is docked at a dock or near the coast, the submarine will also be affected by the tsunami, and may even capsize directly, because the closer to the shore, the more powerful the tsunami is, and even aircraft carriers may not be able to withstand it. .

Finally, the principal believed that when a tsunami occurs on the sea surface, unless it is a very large tsunami, ordinary tsunami submarines will not be affected. Of course, this is also related to the location of the submarine. If the submarine is in It's basically fine in the deep sea, but if you dock on the shore, you may also suffer.
