The test of a wave

Waves measuring 27ft from peak to trough were seen off Land’s End as the stormy weather continued. How do these compare with the highest waves ever measured?

— Waves of 67ft were measured by a buoy off the coast of Donegal in December 2011, the highest found around the British Isles.
— The highest wave yet recorded during a storm was one of 91ft during Hurricane Ivan in August 2005.
— A landslip in Lituya Bay, Alaska, on 9 July 1958 created a local tsunami which tore down trees 200ft above sea level. Water directly opposite the landslip site splashed to a height of 1,720ft, tearing down trees even at that height.
