Darwin arch collapsed due to seawater erosion. What happened here after the collapse?

Darwin Arch collapsed on May 17 due to seawater erosion, and the world-famous Darwin Arch collapsed on May 17 local time because it was eroded by seawater all the year round.

It is reported that it was once the ultimate punching place for countless photographers and divers. But it can't resist the perennial seawater erosion.

Galapagos Islands is a famous tourist and adventure resort, which consists of 13 small islands and 19 rocks solidified by submarine volcanic lava. The island's diverse climate and the special natural environment of volcanic landforms make animals and plants with different living habits grow and breed on this land at the same time. It's called. Museum of biological evolution? It is full of exotic flowers and plants, rare birds and animals. There are many kinds of rare animals in other parts of this archipelago. Darwin, a famous biologist, visited here in 1835, which was the inspiration for his writing Evolution. This famous arch is named after Darwin.

/kloc-in 0/6, Ecuador announced visa-free access to China. A few years before the outbreak, many tourists from China went there. Unfortunately, this famous arch can no longer be seen at the scene. Under the erosion and impact of seawater, this kind of arch on the sea has a great chance of being damaged. A few years ago, there was a very similar example. Malta is famous in the Mediterranean? Blue window? Be eroded and collapsed by seawater, and no longer exist.

I think, if conditions permit, the local government can take some measures to prevent seawater erosion.

The simplest method is coating. In the anode reaction zone where the metal under the coating is corroded, metal ions such as Fe2 produced by corrosion can be freely transferred to the environmental medium through the micropore gap of the coating, and the coating is usually not damaged. It is found that when the corrosion products diffuse outward, the transmission coefficient decreases and the polarization resistance increases, which seems to indicate that the shielding performance of the coating has been improved. However, with the progress of metal corrosion and the secondary reaction under the coating, the volume of corrosion products increased and the accumulated products were destroyed due to the transmission retardation in the micropore gap channel of the coating, which quickly disappeared. At this time, the degradation process of coating performance intensifies, and the corrosion of environmental media to the metal under the coating also increases rapidly.

Well, that's all I want to share in this issue.
