An eight-story monster wave that crashed down in the Southern Ocean off the coast of New Zealand has set a record. It's the largest known wave to ever hit the Southern Hemisphere, according to New Zealand scientists.
Nobody actually saw the 78-foot-tall (23.8 meters) wave crash down, but a buoy moored by New Zealand's Campbell Island managed to log the amazing wonder on May 8, according to MetOcean Solutions, a subsidiary of the Meteorological Service of New Zealand.
The colossal wave eclipsed its record-breaking predecessor by nearly 6 feet (1.77 m). That wave - a 72.2-foot (22.03 m) swell recorded by an Australian buoy, reared up just south of Tasmania in 2012, MetOcean Solutions said.
"This [new wave] is a very exciting event and to our knowledge it is [the] largest wave ever recorded in the Southern Hemisphere," Tom Durrant, a senior oceanographer with MetOcean Solutions,
said in a statement. "This is a very important storm to capture, and it will add greatly to our understanding of the wave physics under extreme conditions in the Southern Ocean."
In this case, a deep, low-pressure system and high winds exceeding 74 mph (65 knots or 120 km/h) helped to create the perfect conditions for the enormous wave. "What is interesting about [Tuesday's] event is the storm speed appears to match the wave speed, allowing wave heights to grow dramatically as the system tracks eastward," Durrant said.
