A cosmic smash-and-dash off the Yorkshire coastline sent a mega-tsunami taller than Big Ben crashing across the ancient North Sea — and scientists have finally confirmed it.
After two decades of bitter dispute, researchers claim a 160-metre-wide space rock ploughed into what is now the southern North Sea roughly 40 million years ago, gouging out a concealed crater and generating a wave exceeding 100 metres (330ft) in height.
Shocked minerals and state-of-the-art seismic scans leave “no doubt” that the enigmatic Silverpit structure — buried 700 metres beneath the seabed and approximately 80 miles off the coastline — is a rare, exceptionally well-preserved impact crater, according to Science Daily.
The findings, published in Nature Communications, overturn years of scepticism. Since geologists first identified Silverpit’s distinctive bullseye pattern in 2002 — a three-kilometre-wide crater encircled by circular faults extending roughly 20km — experts have been divided: asteroid strike, shifting underground salt, or volcanic collapse?
Back in 2009, a room full of scientists voted against the asteroid theory. However, the latest evidence has swept aside all remaining doubts.

Dr Uisdean Nicholson, from Heriot-Watt University in Edinburgh, who spearheaded the research, admitted his team has been “exceptionally lucky” after combining cutting-edge seismic imaging with samples retrieved from an offshore oil well.
Buried at the base of the crater floor, researchers uncovered ultra-rare ‘shocked’ quartz and feldspar — microscopic crystals bearing the scars of pressures so tremendous they can only be produced by violent impacts. Dr Uisdean Nicholson said: “These prove the impact crater hypothesis beyond doubt.”
According to the team’s modelling, the asteroid struck from the west at a shallow angle, hurling a 1.5-kilometre-high wall of seawater and pulverised rock skyward within minutes.
As that towering column collapsed, it unleashed an enormous tsunami across the region — a prehistoric behemoth wave that would have utterly dwarfed any modern storm surge.
Prof Gareth Collins of Imperial College London — who participated in the 2009 debate and contributed the latest simulations — described the new findings as “the silver bullet” that conclusively settles the dispute.
“We can now get on with the exciting job of using the amazing new data to learn more about how impacts shape planets below the surface,” he said.
