The strike displaced huge volumes of water in an ocean about 2,600 feet (800 m) deep, generating tsunami waves exceeding 2,600 feet (800 m) near the impact and sending megawaves across the Atlantic that

Formed around 66 million years ago near the time of the dinosaur extinction, high‑resolution 3D seismic imaging reveals it was gouged by an approximately 1,500‑foot (400–500 m) asteroid striking the seafloor

Beneath the Atlantic, researchers have mapped the Nadir Crater, a nearly 5.7‑mile (9.2 km) impact structure buried under about 1,000 feet (300 m) of sediment on the Guinea Plateau.
