The largest wave ever observed in the southern hemisphere reached a height of 23.8 meters, according tothe New Zealand Meteorological Service. It was recorded by a lone buoy during a storm in a remote part of the Southern Ocean, which records the waves only for 20 minutes every three hours. Researchers note that the buoy could well miss the wave and more.
A new record broke the previous one, which belonged to a wave of 22.03 meters high, registered by an Australian buoy south of Tasmania in 2012.
On January 1, 1995, a wave of 25.6 meters in height was registered in the Northern Hemisphere. She was nicknamed a wave-killer. To monitor such waves from a high-rise building, there are networks of drifting buoys.
Often, giant waves arise due to earthquakes that cause a tsunami. The earthquake in the Indian Ocean and the tsunami caused by it in 2004 claimed the lives of 230,000 to 300,000 people. The height of the waves then exceeded 15 meters.
