Giant Crack in Africa Will Become New Ocean

A 35-mile rift in the desert of Ethiopia will eventually become a new ocean or sea, researchers now confirm.

The crack, 20 feet wide in spots, opened in 2005. Some geologists believed then that it would spawn a new ocean. But that view was controversial, and the rift had not been well studied.

A new study involving an international team of scientists and reported in the journal Geophysical Research Letters finds the processes creating the rift are nearly identical to what goes on at the bottom of oceans, further indication a new sea is in the region's future.

The same rift activity is slowly parting the Red Sea, too.

Using newly gathered seismic data from 2005, researchers reconstructed the event to show the rift tore open along its entire 35-mile length in just days. Dabbahu, a volcano at the northern end of the rift, erupted first, then magma pushed up through the middle of the rift area and began "unzipping" the rift in both directions, the researchers explained in a statement today.

"We know that seafloor ridges are created by a similar intrusion of magma into a rift, but we never knew that a huge length of the ridge could break open at once like this," said Cindy Ebinger, professor of earth and environmental sciences at the University of Rochester and co-author of the study.

The result shows that highly active volcanic boundaries along the edges of tectonic ocean plates may suddenly break apart in large sections, instead of in bits, as the leading theory held. And such sudden large-scale events on land pose a much more serious hazard to populations living near the rift than would several smaller events, Ebinger said.

"The whole point of this study is to learn whether what is happening in Ethiopia is like what is happening at the bottom of the ocean where it's almost impossible for us to go," says Ebinger. "We knew that if we could establish that, then Ethiopia would essentially be a unique and superb ocean-ridge laboratory for us. Because of the unprecedented cross-border collaboration behind this research, we now know that the answer is yes, it is analogous."

The African and Arabian plates meet in the remote Afar desert of Northern Ethiopia and have been spreading apart in a rifting process — at a speed of less than 1 inch per year — for the past 30 million years. This rifting formed the 186-mile Afar depression and the Red Sea. The thinking is that the Red Sea will eventually pour into the new sea in a million years or so. The new body of water would connect to the Red Sea and the Gulf of Aden, an arm of the Arabian Sea between Yemen on the Arabian Peninsula and Somalia in eastern Africa.

Atalay Ayele, professor at the Addis Ababa University in Ethiopia, led the investigation, gathering seismic data with help from neighboring Eritrea and Ghebrebrhan Ogubazghi, professor at the Eritrea Institute of Technology, and from Yemen with the help of Jamal Sholan of the National Yemen Seismological Observatory Center.

And, thus, a sea was conceived.

Just saying

 

[GrnMarvl14]

We can call it the Moses Rift.

Good thing we know what is going to happen a million years from now.

 

[Ho-oh]

Damn it I have to stop partially reading thread topics
Came into this thread with the wrong crack in mind

This is why people need to fund the aquatic reasearch to find what's on our planet instead of looking at stars and galaxies we will never have the technology to come in contact with, atleast not in our time

But like they say, the future of mankind is in space (or as the sci-fi buffs say, the final frontier).

After all, what happens once Earth's resources have been exhausted? We could mine the moon or even mars within the next fifty years I bet.

Another few hundred and we may have the tech to reach distant stars more quickly than ever.

Too bad everyone who lives at this time would be bones or dirt...

Do not get me started on the impracticality and impossibility of this.

Fine, that's a bit too far-fetched, but still. It's bound to happen sometime (but if you were talking about the resources, I didn't mean running out of resources in 50 years).
