A mighty wave towering 62.3ft (19 metres) at a remote spot between Britain and Iceland has become the highest ever recorded.
Data from an automated buoy showed that it rose on Feb 4, 2013 in the North Atlantic, the World Meteorological Organization said.
"This is the first time we have ever measured a wave of 19 metres. It is a remarkable record," WMO's deputy chief Wenjian Zhang said.
Taller than a six-storey building, the wave occurred after a "very strong" cold front had barrelled through the area, producing winds up of 43.8 knots (50.4 miles an hour).
The previous record for the tallest wave was 18.3m, also in the North Atlantic in December 2007.
