The sequence of huge earthquakes that struck off the coast of Sumatra in April may signal the creation of a new tectonic plate boundary. Scientists give the assessment in this week's Nature journal. They say their analysis of the tremors - the biggest was a magnitude 8.7 - suggests major changes are taking place on the ocean floor that will eventually split the Indo-Australian plate in two. It is not something that will happen soon; it could take millions of years. "This is a process that probably started eight to 10 million years ago, so you can imagine how much longer it will take until we get a classic boundary," said Matthias Delescluse from the Ecole Normale Superieure in Paris. Dr Delescluse is an author on one of three scholarly papers in Nature discussing the 11 April quakes.

It is not something that will happen soon; it could take millions of years. "This is a process that probably started eight to 10 million years ago, so you can imagine how much longer it will take until we get a classic boundary, Then they contradict themselves and say it's a VERY GRADUAL process happening over many millions of years and not to hold our breaths ... nothing to see here, folks ! So, which assessment do we go with ... hmmm ? Originally posted by Wrabbit2000 In terms of how fast this could happen? Look at the underwater cities that became submerged somehow and probably pretty quickly. The coast off Florida has ruins and evidence of intelligently laid out 'roads' and heck. Originally posted by Nyiah As for the poster who claimed they were contradicting themselves by claiming "significant", and then downplaying, um, I think your reading comprehension needs a little work. They said it's major changes, but they're going to take a LONG time to complete and form a new plate. It's still a very major change, just not a fast one. Sorry if it's not lickity split fast enough for you. Damn instant gratification generation *shrugs & meanders off* In another new study, Fred Pollitz at the US Geological Survey in Menlo Park, California, and his colleagues found that the global rate of quakes with a magnitude of 5.5 or greater increased almost fivefold in the six days after 11 April - something that has never been seen before, even after very large earthquakes (Nature, DOI: 10.1038/nature11504). Originally posted by tauristercus The operative statement from above is "something that has never been seen before, even after very large earthquakes" which implies that on 11 April, a critical point may have been reached (and passed) that could unpredictably determine the rate at which further future splitting takes place. Sure, could be another 10 million years or could just as likely be next year ... thats why Chaos Theory was invented. Additional small changes could result in massive unpredictable and unforeseen effects.

Niz moćnih potresa koji u su travnju uzdrmali obale Sumatre mogao bi biti znak da se stvara nova granica tektonske ploče, odnosno da se lomi dno oceana, pokazalo je novo istraživanje Prema izvješću predstavljenom u uglednom časopisu Nature niz nedavnih potresa, u kojem je najsnažniji bio magnitude 8,7, pokazuje da bi se Indo-australska ploča mogla raspuknuti u dvije. No to nije nešto što će se dogoditi odjednom već kroz milijune godina. 'To je proces koji je vjerojatno počeo prije osam do deset milijuna godina pa možete zamisliti koliko će još trebati da se stvori klasična granica ploča', rekao je Matthias Delescluse iz Ecole Normale Superieure u Parizu. Sumatra se nalazi na mjestu sudaranja Indo-australske i Sundanske ploče. Ovi golemi dijelovi čvrste Zemljine kore približavaju se jedan drugome brzinom od pet do 10 centimetara godišnje. Izdužena Indo-australska, koja se proteže najvećim dijelom Indijskog oceana, podvlači se pod Sundansku na kojoj se nalaze otoci Indonezije. Trenje koje pritom nastaje uzrok je većine moćnih potresa od kojih je jedan 2004. uzrokovao tsunami. Međutim, podrhtavanje tla 11. travnja 2012., iako je bilo golemih razmjera, nije uzrokovalo nikakav tsunami. Znanstvenici smatraju da se ovakve razlike u Karta novih potresa efektima mogu objasniti prirodom rasjeda. Naime, čini se da je novi rasjed tzv. horizontalnog tipa koji, za razliku od vertikalnih, ne stvara tsunamije. Osim toga travanjski potresi zbivali su se mnogo zapadnije na samoj Indo-australskoj ploči u području koje je puno velikih deformacija i brojnih raspuklina. Delescluse kaže da kretanja na krajevima ploče očito utječu na njezinu sredinu. 'Australija se već kreće u odnosu na Indiju kao i Indija u odnosu na Australiju', rekao je i dodao: 'Razdvaja ih mnogo rasjeda. Ako pogledate Zemlju danas, među pločama uvijek postoji samo jedan rasjed. Dakle, u procesu o kojem mi govorimo iz više rasjeda stvara se jedan. To je pitanje – mi ne znamo koliko treba da jedan oslabi i lokalizira sve deformacije te da svi ostali prestanu biti aktivni. Trenutačno je u Indijskom oceanu aktivno cijelo mnogo rasjeda.' - Sviđa vam se članak? Preporučite ga prijateljima putem ovih servisa: Pošaljite mailom
