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

Massive megaripples, formed by the tsunami after the Chicxulub asteroid impact 66 million years ago, have been mapped deep beneath Louisiana using 3D seismic data. The formations, averaging 52 feet in height and spanning 900 square miles, offer new insights into the force of the ancient tsunami and its global impact. Scientists suggest these findings can help model fu…
