Zhangzhou 1 1 people were involved in seawater and died. What is the cause of death?

17 foreign tourists came to the beach near Zhenjiangkou Village, Qianting, Zhangpu County, Zhangzhou City, Fujian Province. 17 people were accidentally caught in the sea by the undercurrent. After the search and rescue work of local authorities, it was determined that 1 1 person drowned and 6 people survived.

As soon as this news came out, the whole country felt extremely sorry for this 1 1 person. 1 1 People fell into the water and died, 10 Many families were broken. Then why is there a hidden danger under the seemingly calm sea, and how did this 17 person inexplicably fall into the water?

A local homestay staff said that there was no typhoon and no rain on the day of the incident, but? The sea is rough. According to the tidal forecast of Fujian Ocean Forecasting Station, the second high tide in Zhangpu County of Zhangzhou City is at 17: 32. The tidal height is1.68m. ..

? Before being swept away by the undercurrent, 17 people were all holding hands to catch waves in shallow waters. Witnesses said that this 17 person was holding hands in the shallow sea area before being swept away by the undercurrent, and the waves were broken calmly, which didn't look dangerous at all. But suddenly caught in the sea by the undercurrent, only one person was not caught in the sea because he was in charge of taking pictures.

These more than ten people underestimated the power of the sea. Although it looks safe on the coast, it is actually dangerous at high tide. In addition, fewer people can escape in the rapids.

? The accident may have been caused by a torrent. According to the report that 17 fell into the water and1/man drowned, then the high tide time of two hours in advance is the safe time to play on the beach. Usually there is no danger at this time. During high tide, people must stay away from the coast. After being swept into the deep sea by the waves, few people can get away with it.

The accident may have been caused by a torrent. According to the reports that 17 fell into the water and1/people drowned, I think they probably encountered terrible rip currents and rip currents, which are very dangerous, but the seemingly calm sea surface actually hides a mystery.

According to the witnesses at the scene, 17 foreign tourists are playing with water hand in hand at the seaside, and another 1 tourist is responsible for taking pictures of this 17 tourist. Suddenly a big wave swept in. This 17 foreign tourists were all involved in the sea, and all disappeared after 10 minutes. 18 tourists, only 1 person in charge of taking photos survived and was not swept away by the big waves.

? In many coastal cities, rapids are very common, but they are also the most dangerous. In many coastal cities, rapids are very common, but they are also the most dangerous. Because only a few people know the danger of rip current. If it is not handled properly, it will be life-threatening.

The reason for the formation of fissures is very special. It is due to the topographic fluctuation of the seabed near the coast caused by natural forces or manpower, which leads to the difference of water delivery when seawater beats the coast and produces a small-scale ocean current phenomenon.

? It is equivalent to filling a basin of water, blocking the upper and lower outlets at the same time, and then pulling out the plug to feel the downward suction of the water flow. Simply put, it is equivalent to filling a basin with water, blocking the upper and lower outlets at the same time, and then pulling out the plug to feel the downward suction of the water flow. At this time, your hand is equivalent to a person swept away by the sea, and the water flow at the lower outlet is equivalent to rip flow.

There are several ways to judge rip current. In addition to the strong undercurrent at high tide, it is also necessary to observe the nearby waters by analyzing the causes of fissures. The height difference between the seabed directly below the crevasse and the seabed on both sides is obviously different. The seabed below the crevasse is obviously low and gully-shaped.

? It is precisely because of the low terrain below rip current that you can see the waves coming in the distance. If the waves on both sides are more broken, but the waves in the middle are unusually calm, it means that rip flow has been formed. There is a notorious fissure near the Dinosaur Bay in Hawaii, just above the artificially excavated submarine canyon. Many swimmers here will avoid the rapids here.

Due to the low terrain below rip current, the color difference of seawater can be clearly observed by naked eyes when looking down from a height. The seawater on both sides is lighter in color, while the seawater at the location where the fissure occurs is deeper.

? Many coastal tourist cities will erect warning signs on beaches where rip flows occur, and many coastal tourist cities will erect warning signs on beaches where rip flows occur to remind tourists to pay attention to rip flows at all times. Therefore, when you go to a strange beach, you must observe the surrounding waters to see if there are any warning signs.

Even experienced swimmers will be at a loss if they are swept into the deep sea by rapids. So first of all, we must remind ourselves to stay calm and not to struggle unnecessarily. If you choke because of panic, it is easy to drown. ?

So, just being caught in the sea by rapids, don't waste your energy, just let nature take its course, seize the opportunity to call for help or save yourself, relax yourself, float on the backstroke, reach out to the rescuers on the shore and call for help loudly.

At this time, you should swim perpendicular to the current direction and parallel to the coast. The fissure flow has a certain width, ranging from ten meters to several hundred meters. So as long as you swim out of the rapids, you can easily swim back to the coast.
