The probability of large asteroid impacts has increased
The probability of large asteroid impacts has increased.

This does not mean that it has discovered an asteroid that is on a collision course with us, at the moment there is no known asteroid larger than a kilometer that poses a danger to the earth for at least the next 100 years.
What the researcher did was a statistical examination and he realized that there were serious errors in the measurement of some craters. Specifically, he studied four impacts that had occurred in the last million years, two of them located outside of Latin America, the one in Pantasma in Nicaragua. and that of Iturralde in Bolivia, in addition to another two located in Ghana Africa and Kazakhstan Central Asia.

Why is there such a big difference in the measurements, because initially the erosion and movements of the earth's crust were not correctly calculated, which ended up blurring the outer edge of the crater.
The impact that generated the phantom was equivalent to 727,000 megatons and was enough to set fire to part of the earth's atmosphere and distribute the effect of the shock wave and its impact worldwide.
There could be more to discover or even if they are already known their dimensions are miscalculated, this means that the risk is greater than what was thought until now, although as I said before there are no known risks in the next 100 years but the Tic Tac continues in march, it happened in the past and it will happen in the future, the impact with a large asteroid that creates a crater like Pantasma or Iturralde is only a matter of time.
Therefore, the sooner we are prepared for planetary defense, the better it will be for us, the better it will be for the earth and it will also be a step in our evolution as a civilization.
