EXCERPT: . . . A shield wall more than 40 kilometers tall pushes outward from the impact site as bits of ejecta rain back down before plunging into ocean. On the other end of the chaos is a wave a mile high. Researchers plugged that wave into ocean models to reveal a global tsunami event which dredged up the seafloor.

“The impact tsunami had 30,000 times more energy than the 2004 tsunami. The Indian Ocean tsunami caused massive devastation and a lot of lives were lost. So, to have an event that was 30,000 times that is crazy, and that wasn’t even the biggest thing happening that day,” Range said.

As the wave moved outward from the point of impact, it carried all of that kinetic energy with it. As it crossed the oceans, things were relatively calm. Deep waters aren’t largely impacted by tsunami, but as it arrived at distant shores things got more problematic.

The models suggest that the impact tsunami scoured the ocean floor in coastal regions all over the planet. Within 48 hours of the impact, there wasn’t a beach anywhere on Earth which didn’t feel the destructive touch of that wave. Subsequent review of the geological record at more than 100 sites all over the world provided confirmation that sediments deposited just before and after the impact are mixed up in ways we would expect from a global tsunami. Moreover, it’s likely that the waves inundated coastal areas, carrying ocean water at high speeds well into landlocked areas... (MORE - missing details)
