Researchers have discovered four gigantic seamounts towering above the seafloor surrounding South America after detecting " gravitative anomaly " give off by the massive underwater mountains . The tallest ascend more than 1.5 mile ( 2.4 kilometers ) from the seafloor , making it three times taller than the world ’s tall building .
Scientists aboard the Schmidt Ocean Institute ’s Falkor ( too ) enquiry vessel latterly key and mapped the quartet of seamount in the cryptical sea between 286 and 373 miles ( 460 and 600 kilometer ) off the coast of Peru and Chile during an expedition through the East Pacific from Costa Rica to Chile .
The tallest of the newly discovered seamounts is more than 8,000 feet tall.
The three Peruvian peaks valuate 5,220 feet ( 1,591 meters ) , 5,459 foot ( 1,644 m ) and 6,145 foot ( 1,873 m ) tall respectively . But the heavy seamount , establish off Chile , rises 8,796 feet ( 2,681 m ) above the sea ’s bottom , bringing it to within a mile of the airfoil . For comparability , the world ’s tallest building , the Burj Khalifa , is 2,716 feet ( 828 metre ) improbable , while the Empire State Building stands at 1,250 foot ( 380 G ) .
The tallest peak also has a surface area of around 175 square miles ( 450 square km ) , which is around the same size as New Orleans .
These gargantuan underwater peaks , which are all out volcanoes , are so massive that they produce subtle change in the height of the sea ’s control surface , and these so - called gravitational anomalousness can be discover by satellite . In this case , the sea ’s surface bulges in good order above the peaks .
The new seamounts were mapped by researchers onbaord the Falkor (too) research vessel.
" Examining gravitation anomalies is a fancy way of saying we looked for swelling on a single-valued function , and when we did , we located these very with child seamounts,“John Fulmer , the expedition ’s lead technician , said in a financial statement emailed to Live Science .

Last year , the same research team find another monumental seamount that wasaround twice the size of the Burj Khalifa . But there are several bigger submersed passel .
Researchers found the new seamounts using gravitational anomalies.
The world ’s large seamount is technically Hawaii ’s dormant volcano Mauna Kea , according to theWoods Hole Oceanographic Institution . It support at around 13,796 feet ( 4,205 m ) above ocean level but continue to the seafloor , according to theU.S. Geological Survey . Its dead on target peak is around 33,500 feet ( 10,211 m ) .
Scientists suspect that up to 100,000 seamounts are littered across the world ’s oceans , according to the National Oceanic and Atmospheric Administration . However , only a modest fraction of these have been map . More than one-half of these predicted crown are thought to be in the Pacific Ocean .
The latest expedition is part of a new project , named Seabed 2030 , whichaims to map out the entirety of the world ’s seafloor by the end of the current decadeand should let out the rest of these hidden peaks in all their glorification .

Seamounts are often cite to as " biological hotspots " by maritime researchers . The structures provide a hard substrate for immobile creatures such as corals and sponger to ensconce and cause " upwelling " when current drag nutrients from the cryptic sea nigher to the surface . This draw in larger puppet — include crustaceans , Pisces the Fishes , cephalopods and sharks — which makes seamounts extremely important maritime home ground .
" Locating seamounts almost always leads us to understudied biodiversity hotspots,“Jyotika Virmani , executive director of the Schmidt Ocean Institute , say in the argument . " Every metre we detect these bustling seafloor community of interests , we make incredible new discoveries and advance our cognition of life on Earth . "
