A massive asteroid slammed into the North Sea and unleashed a 330-foot tsunami

A decades-long mystery beneath the North Sea has finally been solved. Scientists have confirmed that the Silverpit Crater, buried 700 meters below the seabed, was created when a 160-meter-wide asteroid struck Earth roughly 43 to 46 million years ago. The violent collision blasted a towering curtain of rock and water 1.5 kilometers into the air and triggered a tsunami more than 100 meters high.
