78-foot-tall wave largest recorded in Southern Hemisphere
Scientists have recorded a wave measuring 23.8 metres (78 foot) off New Zealand coast. Equalling an eight-storey building, it broke the previous Southern Hemisphere record of 22.03 metres in 2012, oceanographer Tom Durrant said. The largest wave ever measured 30.5 metres, from an earthquake-generated tsunami near Alaska in 1958, according to Smithsonian magazine.
