globe ’s tectonic plates make our worldunique . Thanks to these prodigious continental and pelagic islands floating atop a partly molten fiendish mantle , we have oceans and batch , volcanoes and earthquakes , and even an aura .
That ’s why a squad of Dutch scientist from Utrecht University has put forward up a fresh database contain everything you ’d need to know about every single subducted tectonic plate ever discovered . These are n’t the single forge the surface world , but those that have since slip into oblivion below .
It ’s even get a rather splendid name:“The Atlas of the Underworld . ”
These 94 gargantuan slabs of rock and roll and flaming are categorized by their age of constitution , their deepness , their locating and more . Featuring sensational optical representation , this undertaking – attach to by an article in the journalTectonophysics – is a masterpiece 17 age in the devising .
Sure , the tectonic crustal plate presently slamming into each other , tearing themselves apart from each other , and slip past each other are those that , for the most part , determine what sort of world we live on . From Antarctica to the Americas , the planet would be an alien one if it was n’t for these remarkable jigsaw pieces .
These once - subducting plateful , however , were creditworthy for incredibly explosive volcanism , cryptic - seated earthquake , and annihilating tsunami . If we desire to understand some of the planet ’s most knock-down natural disasters , and if we want to sympathize both its past and its future tense , this Atlas stand for an essential tool .
Many of thesehidden plateswere observe usingseismology . When certain wave ( primary ) travel through their environment , they move faster through cold , unanimous materials than they do through hot , partly molten materials . Another type of wafture ( secondary ) can only go through solids , not liquidity .
Using this information , geophysicists have revealed to us the internal works of the planet . likewise , this is how these 94 concealed tectonic plate have been identified , and how the Atlas has been created .
These sinking feeling , condemn architectonic plates represent the long - lost surface of the satellite . Over the preceding 300 million age they have completely go bad off , and have been lento descend into the conflagration below ever since .
However , in a very geological sense of the word , they are eventually reincarnate as violent devil .
When a collection plate freefalls into the highly mucilaginous mantle , it dehydrates , then start to dissolve away at the edge between the mantle and the liquid out heart , 2,891 kilometers ( 1,796 miles ) beneath the control surface .
Within this graveyard of tectonic plates , there are at least two unfathomably declamatory liquefied blobs sitting beneath the Pacific Ocean and the African continent . There ’s a chance that these blob are outstandingly hot , break down , and incredibly ancient architectonic plates – and one day , they could transform into buoyant“superplumes”that will rise up and ruin the crust apart .
