In 2015,an expeditionset out to look into the Kavachi submarine vent in the Solomon Islands . The vent had lately had a lull in activity , making it possible to search inside the active volcanic crater .
In the extreme conditions of acidulent water containing high floor of atomic number 16 on top of an active vent , they found more liveliness than they were expecting . As well as microbial species that thrive on sulfur , they discovered two metal money of sharks – hammerheads and thesilky shark – live in the volcanic crater of the volcano . Their finding were release in 2016 in the journalOceanography .
" Populations of gelatinous animate being , small Pisces the Fishes , and sharks were observed inside the fighting volcanic crater , " the squad wrote in their theme , " raising new questions about the environmental science of participating submarine volcanoes and the utmost environment in which large marine animals can exist . "
The team dubbed the vent " sharkcano " , give the large act of sharks apparently happily living in the hot , acidulent waters . Kavachi is site about 24 klick ( 15 miles ) south of Vangunu Island .
" Two metal money of shark , the scallop hammerheadSphyrna lewiniand the silky sharkCarcharhinus falciformis , approached the bait camera multiple time in an aggressive design ; in some cases , sharks appeared to be swimming from great depths inside the crater . "
Satellite images from NASAhave now shown that the creatures chill enough to dwell in a sharkcano may be in for a jumpy ride , as the Kavachi submarine vent is erupting once more .
Images take by the Operational Land Imager-2 on satelliteLandsat 9showed a large plume of discolored water on May 14 , 2022 , emitting from the vent .
harmonise to theSmithsonian Global Volcanism Program , the volcano has seen more activity latterly , beginning with discolored water give out from the volcano in October 2021 . Since the first eruption recorded at the site in 1939 , the vent has erupted about - ceaselessly , though there have been period of relative inactivity . The last major eruptions see from the sharkcano took placein 2014 .
