Reconstruction of countries that have faced natural disasters

Weather of Arabia - The recurrence of earthquakes that struck various regions of the world and the storms and floods that occurred recently, leaving behind huge losses, made the question of how it is possible to avoid the destruction that occurs after natural disasters and rebuild destroyed cities in such a way that the world avoids great losses in the future, that it took part of the answer.

Hence, we highlight Japan, with its history full of earthquakes. How was it able to overcome this problem?

The most earthquake-resistant skyscrapers in the world

An earthquake struck the Japanese coast of Fukushima in 2016 with a magnitude of 6.7 on the Richter scale, while in 2011 a huge earthquake with a magnitude of 9.0 on the Richter scale occurred, which led to the occurrence of several devastating tsunami waves and caused a number of losses. Perhaps the reason behind this is Japan’s location, as it is located along the region called the “Ring of Fire” on the edge of the tectonic plates of the Eurasian, Pacific, and Philippine regions, a location that makes it more vulnerable to earthquakes than any other region.

This necessitated the implementation of solutions and the reconstruction of what was demolished in a way that makes it resistant to earthquakes, so that Japan applied strict standards to buildings, most notably:

• A law that specifies requirements for buildings to resist earthquakes, such as the recommended thickness of columns and walls to cope with ground shaking.
• 3 main design structures for building infrastructure Taishin structure, Seishin structure, Mainshin structure.
• The use of dampers that absorb much of the earthquake energy during construction, so that layers of thick rubber maps are placed on the ground to absorb the tremors to a large extent.

Through these and other standards, Japan has become one of the leading countries in constructing the most flexible buildings in the world.

From Japan to South Korea, where it is planning unconventional endeavors to confront the effects of climate change and the resulting natural disasters, specifically floods; And that's where the idea came from.

Floating cities

A city floating on the surface of the water rises and falls based on sea levels and water levels so that it “does not sink.” This description is not a fantasy. Rather, it represents a plan to build the first “floating city” resistant to floods, which the city of Busan in southern South Korea will begin work on and is expected. To be ready for housing by 2025.

The floating port will represent a solution for coastal cities threatened by floods, as the city’s houses will take the form of floating platforms made to be later transported to their location, in buildings reaching a height of 7 floors, noting that each neighborhood will extend over an area of 5 acres, housing about 300 people.

Among the most prominent features of this city:

• Its neighborhoods are connected in the project through a network of paths and corridors that allow movement according to the designs.
• Self-sufficient, no waste
• It includes hydroponic farms and power plants that generate energy through the power of wind and sunlight.
• The presence of water treatment centers and rain storage warehouses
• Transportation by electric cars and solar-powered ferries to transport residents to the mainland.

There has always been hope among the clouds of despair, and perhaps the debris left by natural disasters throughout the world may be a reason for arriving at fundamental solutions that will make the future free of losses resulting from natural disasters.
