Modeling predicts supercontinent Amasia will form in 300 million years

Amazing stuff! Will humans still be around to witness it? 

Which of the oceans will ultimately close next time to form a supercontinent, the Pacific Ocean, the Atlantic Ocean, or both together, or the Indian ocean?

Will plate tectonics ever stop or slow down? Quite possible!

"New modeling from researchers at Curtin University has simulated 300 million years of tectonic plate movement to predict the formation of a supercontinent called Amasia. The modeling estimates the Pacific Ocean closing and America colliding with Asia. ...
“Over the past two billion years, Earth’s continents have collided together to form a supercontinent every 600 million years, known as the supercontinent cycle,” ...
The most recent supercontinent was Pangaea, which came together around 335 million years ago and began to break up at the beginning of the Jurassic age 200 million years ago. ...
But unsurprisingly, there are plenty of hypotheses speculating how the world’s continents will shift over the next few hundred million years. One configuration, dubbed Pangaea Proxima, suggests the Atlantic and Indian oceans will ultimately close, creating a supercontinent not entirely unlike Pangaea. Another hypothesis proposes the Atlantic and Pacific oceans will both close, with a rift splitting Eurasia from India to the Arctic creating a supercontinent called Aurica. ..."

From the abstract:

"Earth's known supercontinents are believed to have formed in vastly different ways, with two end members being introversion and extroversion. The former involves the closure of the internal oceans formed during the break-up of the previous supercontinent, whereas the latter involves the closure of the previous external superocean. However, it is unclear what caused such a diverging behavior of supercontinent cycles that involved first-order interaction between subducting tectonic plates and the mantle. Here we address this question through 4-D geodynamic modeling using realistic tectonic setups. Our results show that the yield strength of the oceanic lithosphere plays a critical role in determining the assembly path of a supercontinent. We found that high oceanic lithospheric strength leads to introversion assembly, whereas lower strength leads to extroversion assembly. A theoretically estimated reduction in oceanic crustal thickness, and thus its strength, during Earth's secular cooling indicates that introversion was only possible for the Precambrian time when the oceanic lithosphere was stronger, thus predicting the assembling of the next supercontinent Amasia through the closure of the Pacific Ocean instead of the Indian-Atlantic oceans. Our work provides a new understanding of the secular evolution of plate tectonics and geodynamics as the Earth cooled."

Modeling predicts supercontinent Amasia will form in 300 million years

Pacific Ocean set to make way for world’s next supercontinent New Curtin University-led research has found that the world’s next supercontinent, Amasia, will most likely form when the Pacific Ocean closes in 200 to 300 million years.

Will Earth's next supercontinent assemble through the closure of the Pacific Ocean? (open access)
