Q: Scientists have recorded what is believed to be the largest wave ever in the Southern Hemisphere, a 78.1-foot (23.8 metre) monster the height of an eight-storey building. 
  
 A buoy recorded the wave on Tuesday during a ferocious storm in the notoriously wild Southern Ocean near Campbell Island, some 435 miles (700km) south of New Zealand, research body MetOcean Solutions said. 
  
 Senior oceanographer Tom Durrant said it wiped out the previous Southern Hemisphere record of 72.3 feet (22.03 metres) from 2012. 
  
 “To our knowledge it is largest wave ever recorded in the Southern Hemisphere,” he said, adding that the Southern Ocean was an “engine room” for generating swell waves that move across the planet. 
  
 “Indeed, surfers in California can expect energy from this storm to arrive at their shores in about a week’s time,” he said. 
  
 Durrant added that even bigger waves topping 82 feet (25 metres) were probably whipped up by the storm, which tracked east through the area on Tuesday, but the buoy was not in the best place to record them. 
  
 He said the buoy, installed in March to measure the extreme conditions in the Southern Ocean, also only recorded for a 20-minute burst every three hours to conserve its batteries. 
  
 “It’s very probable that larger waves occurred while the buoy was not recording,” he said. 
  
 The largest wave ever noted was an earthquake-generated tsunami at Alaska’s Lituya Bay in 1958 that measured 30.5 metres, according to Smithsonian magazine. 
  
 Brazilian surfer Rodrigo Koxa was recently acknowledged as having ridden the biggest wave ever surfed, am 80-foot (24.38 metre) giant at Nazare in Portugal last November. 
  
 But unlike the wave heights recorded by ocean buoys, the height of this wave was decided by a matter of estimation, based on comparing it to Koxa’s crouching height in photos. ||||| Image copyright Getty Images Image caption The wave was measured by a buoy at Campbell Island in the Southern Ocean 
  
 Scientists in New Zealand have documented what they believe is the largest wave ever recorded in the southern hemisphere. 
  
 The 23.8m (78ft) wave was measured by a buoy on New Zealand's Campbell Island in the Southern Ocean on Tuesday, the country's weather authority said. 
  
 It eclipses a 22.03m wave that was identified south of the Australian state of Tasmania in 2012. 
  
 Larger waves have been recorded in the northern hemisphere. 
  
 The Meteorological Service of New Zealand (MetService) installed its solar-powered buoy in March. The area is known for big storm activity, but waves had been previously difficult to measure. 
  
 Bigger waves possible 
  
 The "eight-storey high" wave was generated by a deep low pressure system and 65-knot winds, said MetService senior oceanographer Dr Tom Durrant. 
  
 "This is a very exciting event and to our knowledge it is the largest wave ever recorded in the southern hemisphere," he told the BBC. 
  
 The buoy operates for 20 minutes every three hours. Dr Durrant said it was possible that even bigger waves were generated by the storm but not recorded. 
  
 The World Meteorological Organization does not hold official records on individual wave heights. Instead, it records an average of successive swells - a measure known as the "significant wave height". 
  
 During the storm recorded by New Zealand, the significant wave height was 14.9m. 
  
 That is a record for the Southern Ocean but below a 19m mark measured by a buoy in the North Atlantic in 2016, Dr Durrant said. 
  
 He said storms moved across the Southern Ocean largely unhindered due to a lack of land. 
  
 "[It is] the engine room for generating swell waves that then propagate throughout the planet," he said. 
  
 "Indeed surfers in California can expect energy from this storm to arrive at their shores in about a week's time." ||||| A solitary buoy in the remote Southern Ocean has recorded a monster wave of 23.8 metres, the largest wave ever measured in the southern hemisphere. 
  
 A wave rider buoy moored at Campbell Island off New Zealand's South Island registered the huge wave on Tuesday, according to Tom Durrant, a senior oceanographer at Metocean, part of Meteorological Metservice of New Zealand (MetService).

 Since the buoy only registered the first 20 minutes of each three hours, "it's quite possible, even probable, that there were much higher waves during this storm", Dr Durrant said. 
  
 It eclipsed the previous record maximum individual 22.03 metres clocked at an Australian buoy south of Tasmania in 2012. 
  
 The so-called significant wave height for the event, which is an average of the top third of waves measured from their crest to trough, was registered at 14.9 metres. |||||
A:
The northern hemisphere still has it beat, but the southern hemisphere can now claim a new record when it comes to tallest wave. A solar-powered buoy placed near New Zealand's Campbell Island in the Southern Ocean on Tuesday recorded an eight-story wave that measured 78 feet in height, beating out the 72-foot wave recorded south of Tasmania in 2012. Tom Durrant, an oceanographer with the Meteorological Service of New Zealand, tells the BBC the Southern Ocean is "the engine room for generating swell waves that then propagate throughout the planet. Indeed surfers in California can expect energy from this storm to arrive at their shores in about a week's time." And as far as the Southern Ocean goes, it's "definitely the most under-observed ocean in the world," he tells the Sydney Morning Herald. The buoy has been in place since March in order to observe the extreme conditions that can occur there, and Durrant notes that to preserve its battery life it only keeps records for one 20-minute span out of every three hours. That, combined with the fact the buoy wasn't perfectly positioned during the storm, means it's "probable" a bigger wave actually occurred, reports the South China Morning Post. (The tallest wave recorded took place in Alaska's Lituya Bay in 1958.)
