What crises are hidden in the endless blue sea?

For a thing, the observation results from different angles are different, and the sea is like this. The ocean on a sunny day looks pleasant, but when night falls, it will "swallow up" everything like a "nightmare". Although human science and technology are relatively developed and there are many means to detect the seabed, these oceans are still "frightening", and several terrible ocean phenomena make people feel very strange.

"Killing waves" People who often drift on the ocean have seen such waves. Some waves are higher than others, and when they are superimposed, they can achieve considerable power. This kind of wave is also called "killing wave" because it can cause harm that ordinary people can't imagine. Many people living inland have never seen such waves, thinking that the probability of such waves is low, but in fact, under the right conditions, the probability of "killing waves" is very high.

This kind of spray is fierce, usually a relatively "sudden" wave caused by a certain geographical environment. Because the seabed is close to sea level and unstable, waves will be superimposed. In some places with steep terrain, this "superimposed wave" can even directly smash the ship. In addition, this splash happened suddenly, and even many experienced sailors could hardly avoid it.

The "Mexican Warm Current" is in a narrow sea area, and there is also a Mexican warm current similar to the "through flow". This warm current comes from a wider sea area outside, and when it passes through a relatively narrow sea area, it will form a force, which can make the ship lose power and cannot move, so it can only drift to a remote place with the Mexican warm current. Rescuers often go to the scene of the accident, but at this time the accident ship is often not found because it has been "forced" to go to other places.

In addition to the two marine phenomena mentioned above, there is another marine phenomenon that everyone is familiar with, and its power is incomparable to the above two phenomena, that is, tsunami. Many people may have simply heard of the tsunami, thinking that the tsunami is just a big wave hitting the coast, which will affect the living standards of coastal residents at most. But this is not the case. The "power" of tsunami is beyond people's imagination.

"Tsunami" attack Generally speaking, the reason for the formation of tsunami is mainly due to the violent fluctuation in a certain place near the coast, which leads to the generation of quite huge waves, which splash up and form a tsunami. So the tsunami is only a result of destruction, and the real "lethality" is often the cause of the tsunami. Tsunamis can be caused by many reasons, such as the explosion of a deadly bomb in water or an earthquake. More common is the submarine earthquake.

Most tsunamis caused by submarine earthquakes have certain destructive power, and the more serious the earthquake, the greater the destructive power. If the focal depth exceeds 50 kilometers and the magnitude exceeds 7, it is not surprising that this earthquake brought a "devastating" tsunami. The waves rolled up by the tsunami can reach tens of meters high, even close to the height of the building where we usually live. Even if everyone can swim, such a high wave can do great harm.
