African desert rift confirmed as new ocean in the making!, page 1

Now I post quite a few Science related stories on ATS, I find them interesting but others don't seem to!

This one comes under that category!

African desert rift confirmed as new ocean in the making

In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial.

A new Ocean forming in the centre of Africa, now I really do find that coool!

Now, scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world's oceans, and the rift is indeed likely the beginning of a new sea.

The new study, published in the latest issue of Geophysical Research Letters, suggests that the highly active volcanic boundaries along the edges of tectonic ocean plates may suddenly break apart in large sections, instead of little by little as has been predominantly believed. In addition, such sudden large-scale events on land pose a much more serious hazard to populations living near the rift than would several smaller events, says Cindy Ebinger, professor of earth and environmental sciences at the University of Rochester and co-author of the study.

It doesn't say how the rift will form into an ocean, or where the water will come from, but it's still amazing.

It's not often in the history of Earth that people can say they witnessed the birth of a new Ocean!

From the British Geological Survey

A BGS team are mapping the geology of the Afar desert in northern Ethiopia — reputed to be the hottest place on Earth.

Afar is part of the volcanically and seismically active portion of the African Rift and is one of the few places on Earth where we can witness plate divergence as the continental crust splits apart to form a new ocean.

The Afar Rift project aims to track the creation of magma (molten rock) from deep within the Earth, studying how it migrates and evolves as it rises towards the surface. We will study how the surface of the Earth reacts as it is thinned and split apart and how the magma is intruded into this thin crust to form the beginnings of a new ocean.

So it looks like the Rift will widen, eventually splitting the continent, becoming an ocean.


(Thanks to fleetlord for bringing this image to my attention!)

But I'm pretty sure it's a few million years away yet, but I still find it interesting!

I'll be the only one as usual!

I've heard that the African continent is splitting into two tectonic plates (the Nubian Plate and Somalian Plate). Africa is supposed to split open right down to Lake Victoria and then out to sea.
Click here - for a more visual form.
The Afar region the source mentions is shaded in red.

It will probably remain a dry valley (not counting rainfall) until the split reaches the Red Sea. I wish I could be there when that happens, imagine an entire sea filling up a valley...

This might be a great opportunity to get a look at what a dry ocean looks like. Maybe we can use it when looking at other water-less planets?

Thanks mate, I added that to the thread, I gave you credit of course!

And you're right on both accounts- I'd love to be there and it may turn up a heap of info!

thanks again!

could more oceans be popping up in other places ?

From what I can gather from good ol' Wiki, divergence of techtonic plates is happening all over the world, except it's usually under the sea.

* The Mid-Atlantic Ridge
* Red Sea Rift
* East African Rift
* West Antarctic Rift
* East Pacific Rise
* Pacific-Antarctic Ridge
* Galapagos Rise
* Gakkel Ridge
* Explorer Ridge

that's why this is so unique!

or where the water will come from

I would think that if this rift opens up toward another body of water, that is where the water would come from. For example, if one end of this rift opened up at the Indian Ocean, water would flood into the rift from the Indian Ocean. As for the water levels, I think it would depend how big this sea ended up being and how deep it was. If it ends up being the size of the Mediterranean, I think that there may be something to worry about. I don't see something Lake Superior size doing much.
