The meteorite hits Earth: 5 countries suffer losses

According to NASA and international scientific forecasts, a meteorite will hit Earth on April 13, 2036 . The latest model established by British scientists has shown that five countries will suffer. many losses in the case of meteorites hitting the Earth. They are China , Indonesia , India , Japan and the US .

NEOpactor software predicts tragedy

Researchers at the University of Southampton, UK, have designed a special computer software program to build various collision models between Earth and asteroids (large meteorites). From there, anticipate potential risks of human and economic losses in each country and region in the world.

According to research results, when an Near Earth Asteroid (NEA) asteroid with a diameter of less than 100 meters hits the Earth - whether on land or in the ocean - it will cause losses. humanity and economy at the same time in many countries.

In the case of a NEA with a diameter of over 200 meters falling into the sea, the consequences are even more serious, because the collision will cause tsunami on a very large scale. And if the NEA has a diameter of 500 meters hitting any ocean, it will cause loss of life and material on a global scale.

The software was built by Nick Bailey, a rocket specialist at the University of Southampton, United Kingdom, UK, and two associates: Dr. Graham Swinerd, of the University of Southampton, and Dr. Richard Crowther, in the Lab Rutherford Appleton experience.

Human and economic losses

After collecting population density data, the expert used NEOimpactor to chart the highest number of possible casualties when asteroids rush into the ocean. Accordingly, countries with large populations in coastal areas will be the most severely affected countries.

Research results have identified the top five countries in the world in terms of human loss, with China ranked first, followed by Indonesia, India, Japan and the United States. The team also created maps showing areas that could be most affected by the NEO collision.

Accordingly, Asia's Pacific coast is the place where there will be the highest casualties, while the North Atlantic region will be the place to generate tsunamis that cause extremely serious impacts on Europe and the North. America. Determining the economic losses of each country is more difficult. But the team did it by basing on infrastructure data in different parts of the world.

Based on these infrastructural characteristics, experts estimated the extent of the devastating tsunamis, earthquakes and ruins generated by a collision to rank countries for the risk of physical damage.

According to research results, the United States tops the group of five countries most at risk of economic losses due to infrastructure destruction, but perhaps not surprisingly, because the country has a lot of lower architectures. floors in coastal areas overlooking two large oceans. Behind the US, in descending order of loss, are China, Sweden, Canada and Japan.

In both the list of casualties and economic losses, the UK ranks 8th.

However, Mr. Bailey notes that these projections will be inaccurate in the event that a NEA does not plunge directly into the Earth but breaks into pieces in the atmosphere of the planet, and then small pieces. It just hit the Earth. He said this case is not within the scope of his research and his research.

Small NEO is much more dangerous

In the course of the study, experts focused on small objects near the Earth (Near Earth Object - NEO) because it had a greater chance of touching the Earth.

On average, for every 10,000 years, a NEO with a few hundred meters in diameter plunges into the Earth, while for objects with a larger diameter, that time is up to 100,000 years. Moreover, small NEOs are difficult to detect, and therefore far more dangerous than the big NEO.

Speaking to New Scientist , Mr. Bailey told: 'The Earth may be hit by an asteroid in a context where we don't have much time to deal with. Therefore, our goal is to focus on the consequences that small NEOs can cause to the planet. '

In the meaning of this study, Nick Bailey said: 'The risk of Earth colliding with asteroids is being recognized as the most terrible natural hazard facing humanity. Therefore, our study predicts the countries at greatest risk, and also shows which countries should actively participate in that risk prevention. '

Meanwhile, Clark Chapman, a scientist at Southwest Research in Boulder, Colorado, USA, thinks that more research is needed to better understand the risk of a possible collision in the future.

According to him: 'each country has different risks and the ability to deal with that risk is different'.
