What goes down must come up – perhaps in the form of molten lava.
When tectonic plates are moved, they pull our ocean deep into the earth’s crust, and that water triggers earthquakes, magma production and volcanic eruptions.  All activities as usual, geologically speaking.
But it turns out that the planet is sucking in much more sea water than we previously thought – triple amount – and it makes researchers nervous.
Using seismic sensors located around Mariana Trench – the deepest point on the planet, where the Filipino Sea meets the Pacific Ocean – a team of scientists from Washington University in St. Petersburg. Louis traced rumblings miles below the surface.
The slower the quakes move, the more water is thought to buffer its wake and the team observed these “falls” almost 1
8 miles in the Earth’s crust.
Although they were temperature-driven and pressed below, researchers investigated at 3 billion teragrams – or one billion kilograms – are deducted every million years.
Although these vast numbers may not offer much context, it helps to know that water entering the Earth will end – through volcanic eruptions – and this, according to researchers, is three times more hydration than the Earth seems to emit for present.
That these numbers do not correlate means that researchers understand much less about the interior of the planet than they thought.
“Many more studies need to be focused on this aspect,” said lead researcher Chen Cai Live Science.
As it shows the new study results, “major consequences,” said Donna Shillington, a researcher at the Lamont-Doherty Earth Observatory at Columbia University, who wrote an up-to-date study.
“If extrapolated globally.” The authors’ results mean that the amount of water entering the interior of the earth significantly exceeds current estimates of the amount emitted by volcanoes and thus requires a review of the global water budget, “she writes.
Shillingtons bottom line: Water under the Earth’s surface contributes to the development of magma and can lubricate errors, making earthquakes more likely.
