3D Mapping Reveals 52-Foot Megaripples from Chicxulub Asteroid in Louisiana

Giant underwater ripples, formed in the wake of the asteroid impact that wiped out the nonavian dinosaurs 66 million years ago, have been identified deep beneath Louisiana's surface. Measuring up to 52 feet high and nearly 2,000 feet apart, these megaripples provide new insights into the catastrophic tsunami triggered by the Chicxulub impact. The findings, based on advanced 3D seismic mapping, have extended the known reach of these formations fa…
