New 3D map reveals dinosaur extinction's tsunami effects

Scientists have created a new 3D map of "mega ripples" on the seafloor caused by the Chicxulub asteroid impact, which led to the extinction of the dinosaurs 66 million years ago. This map reveals the extent and formation of these ripples, which are much larger than previously thought. The study shows that the impact generated a massive tsunami, creating unique geological formations in Louisiana. Researchers found that the ripples were shaped by a combination of tsunami waves and an earthquake that fluidized the sediment. These findings may improve understanding of tsunami impacts and help predict future events. The new map covers over 2,400 square kilometers and indicates the tsunami's direction from the Yucatán Peninsula.
