Researchers have confirmed that Silverpit Crater, buried beneath the southern North Sea, was formed by a massive asteroid impact roughly 43-46 million years ago, ending a decades-long debate over its origin.
The crater, approximately 3.2 kilometres wide with an outer disturbed zone spanning 20 kilometres, was created when a 160-metre-wide asteroid struck the shallow seabed, generating a massive plume and a tsunami over 100 metres (330 feet) high, per Science Daily.
