NEW from NOAA SOS: This dataset shows the tsunami wave caused by the asteroid that hit Earth 66 million years ago. The wave was so impressive because the asteroid is estimated to have been 6+ miles (10+ km) in diameter! Want to learn more? sos.noaa.gov/catalog/datase

Pretty fascinating. I'd be curious to see how far inland on the then-current land the waves went.

So im confused because current science puts the asteroid impact at our *current* Yucatan peninsula, is this because the land it hit is apart of the North American Plate and drifted with the land mass to its current day position

The center of the crater formed by the asteroid is now offshore near Chicxulub, Mexico in the Yucatan Peninsula. It's position has shifted from it's original impact location 66 million years ago due to the movement of the plates. Learn more here: sos.noaa.gov/catalog/datase

I’m assuming that the scale bar is wrong? It shows maximum wave height was 5 m. Maybe it was supposed to be km?

1/2 Good question! The amplitude of the wave reached maybe more than 2.5 miles (4.5 km) in what became the Gulf of Mexico, but quickly became far less massive. In this visualization, the color bar numerical values top out at +/- 5 meters. If we scaled the colorbar to the [...]

The single continent known as Pangea existed approximately 200-300 million years ago. By the time the Chicxulub astroid impacted the Earth 66 million years ago the continents had drifted apart as shown by the black colored land masses.
