An impact like the one that left the Barringer crater could be repeated

The Barringer crater was created about 50,000 years ago by the impact of an asteroid made basically of metal, mainly iron and nickel. The experts estimate that the asteroid measured 50 meters in diameter, that is, the same size as asteroid 2023. of newly discovered DW that has a high probability of colliding with the earth.

The result was a crater 1,200 meters in diameter, surrounded by a ridge that rises some 45 meters above the plain and currently has a depth of 170 meters, although the asteroid originally had to drill much deeper, since they have calculated that there are between 210 to 240 meters of sediments and rocks that accumulated at the bottom of the crater.

Such an impact would devastate everything, they have calculated that the creation of the crater involved the release of a Power of energy equivalent to about 150 times the power of the atomic bomb dropped on Hiroshima, the only consolation is that there would be no radioactive contamination in the event of an impact with an asteroid, but this would be in the worst of the worst possible cases, luckily metallic asteroids are very rare. We are also verifying that a large part of the explored small asteroids seem to be actually a conglomerate of rubble, rocks and dust piled up and united slightly.

Therefore, rather than the impact of a large block like the case of Arizona, which would be something rare, what seems more possible according to astronomers is that there would be a great explosion in the atmosphere with the disintegration of most of the asteroid and a subsequent rain of rubble, some experts compare what could be the impact of this asteroid 2023 DW with what happened in the Tunguska event in Siberia Russia, on June 30, 1908.

The Tunguska event was terrible the explosion in the atmosphere destroyed some 80 million trees in an area of 2,150 square kilometers the thermal wave and the expansive wave killed every living thing that was on the surface of the damaged area, this is what It could occur if the asteroid's entry occurred over land, but statistically it is more likely to occur over the ocean, since waters cover nearly three-quarters of the planet.

To this must be added the hot deserts and the polar regions, so the risk area, that is, the area inhabited by humans, is a relatively small area. The latest statistics show that of the 8,000 million humans that we are 7,300 million occupy 7.6% of the earth's surface, although it must be clarified that the surface occupied by humans has multiplied by 2.5 since 1975 and it seems that it is a trend that will continue to increase, multiplying throughout of this century.

Which means that the "target" of the asteroid, that is, us humanity, has increased and therefore the risk that an asteroid ends up causing damage to humans with its impact has increased.

In the map published by the Italian astronomers that shows that a large part of the risk corridor runs over the Pacific Ocean, but it also runs over some highly populated areas of the planet.
