The United Nations' weather agency today announced the highest wave on record - a monster that towered 19m above the North Atlantic.
Data sent back by a buoy showed a monster wave at 0600 GMT on February 4, 2013 at a remote spot between Britain and Iceland, the World Meteorological Organisation said.
"This is the first time we have ever measured a wave of 19 metres. It is a remarkable record," WMO deputy chief Wenjian Zhang said.
Taller than a six-storey building, the mighty wave occurred after a "very strong" cold front had barrelled through the area, producing winds up of 43.8 knots (81 km/h).
AFP reports the previous record height for a wave was 18.3m, notched up in December 2007, also in the North Atlantic.
