An international team of scientists worked with the NOAA to create a simulation of the 6+ mile wide asteroid that hit Earth 66 million years ago, the one that nearly wiped out all dinosaur species. It triggered a megatsunami with mile-high waves, which is believed to have 30,000 times more initial energy than any recorded events.
In this simulation, the black continents show the land masses at the time of the impact, approximately 66 million years ago, while the white country borders depict where the land masses are today. The tsunami wave amplitude is shown 10 minutes after impact until 48 hours after impact. Once the first 48 hours had passed, the tsunami had mostly subsided except near the point of impact.

This study helps to assess and quantify the risk of future large asteroid impacts. In addition, the ability to reproduce mega-events like this is an important validation that the models can help scientists forecast global impacts of more conventional tsunamis that humanity has to deal with,” said the team.
