Overview

• The Nadir Crater, located beneath the Atlantic Ocean near Guinea, was formed by an asteroid impact 66 million years ago.
• High-resolution 3D seismic data confirmed the crater's formation from a 450-500 meter wide asteroid.
• The impact likely caused a massive tsunami over 800 meters high across the Atlantic Ocean.
• Scientists are exploring the possibility of multiple asteroid impacts contributing to the end-Cretaceous extinction event.
• This discovery offers unprecedented insights into marine impact craters and their formation processes.
