Scientists map enormous underwater megaripples from asteroid impact

New research has revealed that large underwater "megaripples," created by the tsunami from the Chicxulub asteroid impact, extend much farther than previously thought. These ripples, some 52 feet high, were mapped using advanced seismic data. The study analyzed 900 square miles of data, showing megaripples across a wider area than the earlier identified 77-square-mile region. Variations in their shapes and orientations were noted, indicating different tsunami behaviors in various locations. Researchers suggest these megaripples formed from sediment fluidized by a massive earthquake, shaped by high-speed tsunami waves. Understanding these ancient dynamics may help prepare for potential future asteroid impacts.
