The Asteroid Returns
The space rock that ended the age of dinosaurs is called the Chicxulub Impactor. This asteroid was enormous, measuring between ten and twenty kilometers wide, about the size of one to two hundred football fields. In this scenario, it is once again heading straight for Mexico, traveling at a blistering twenty kilometers per second.
Upon impact, the devastation would be instant and overwhelming. The energy unleashed would equal ten billion nuclear explosions. Everything near ground zero would be incinerated. The resulting shockwave would flatten areas within one thousand five hundred kilometers. A magnitude ten earthquake would shake the entire continent. Tsunamis would strike coastal areas in Mexico, Cuba, Texas, and Florida.But that would only be the beginning.
