New Ocean Forming In Ethiopia

Afar Ocean, possibly 10 million years from now

Although the birth of an ocean is an extremely rare phenomenon on the largest of historical scales, the geophysics is currently experiencing such an event. Even more dazzling, this occurs in one of the Earth's most inhospitable and arid regions, the Afar Depression in Ethiopia.

The African continent is literally unstitching itself apart just like the sleeve of an old shirt, along the area known as the East African Rift, which traverses it beginning with the southern end of the Red Sea, going through Eritrea, Ethiopia, Kenya, Tanzania and Mozambique. The molten lava beneath the Earth's surface makes it thin by constantly pushing against it, and eventually breaks it and tears it apart. As the forces that drive the lava from the sinews of the crust don't encounter much resistance anymore, they keep applying unbelievable pressures, widening the gaps. This will all end about ten million years from today, when the Red Sea's water, that will soon flood the rift, will have completely submerged the region.

This scenario is not far from happening, as currently the surface of the continental crust under the Afar Depression is just 20 km (about 12.5 miles)-thick, half its original thickness. There are many portions of the regional landscape situated more than 100 meters (328 feet) below the sea level, and the only thing that keeps the sea water from invading them is the low eastern hills. Such closeness to the planet's boiling blood shape shifted the zone into one of seismic, volcano and hydrothermal activity, a true Eldorado for scientists who have the means to overcome its obstacles. The temperatures in Afar reach 48 degrees Celsius (118 degrees Fahrenheit) during summer days, while there is way too little and too scarce rain to quench the thirst of the land. And, besides the geological issues, the war between Ethiopia and its neighbor, Eritrea, also comes as a deterring factor for any person who would be interested in scientific observations.

The geologists who are involved, though, foresee that the crust will continue to stretch, thin and sink for about another million years, culminating with a massive flood by the Red Sea waters, which in the end will cause the Afar Depression to lay at the bottom of a new ocean. Obviously, none of us will still be alive in order to prove them right or wrong.

For now, the landscape of Afar doesn't look anything like an ocean, instead, it rather appears similar to a hellish design ripped from a video game. Vegetation cannot survive due to the lava beneath, the heat stifles most other life forms, while toxic fumes emanate from strange formations. Thankfully, the salty remains of past Red Sea deluges allow Afar's nomad tribes to make a living out of exportations.

how does this affect us it wil be formed in 1 million years

"how does this affect us it wil be formed in 1 million years " so glad not everyone thinks like you...

Its fascinating. Its science and geology. If you don't care about these things, why read the article or bother to comment on it for that matter?

This article is "trash science" with a lurid headline implying impending doom. Yes, 10 Million years from now something may occur -- but get real! 10 million years??

Another example of the hysteria and hype the permeates all media and publications today from the weather channel hyping hurricanes to the the bozo in England who "accidentally lost all his global warming data" when true scientists asked him to prove his conclusions, but admited no measurable change in global temp in the last 15 years. Warming? All HYPE!

Yopu don't need to go to Africa to explore this phenomema. The Snake River valley in Idaho was formed by the same type of underlying molten magma in a rift. It is what created the "wonders' at Yellowstone Park. Other geophysical scientists predict that Yellowstone's magma vault may colappse into a SUPER-volcano in the next 100 - 1000 years. That's immenient in geological terms, not the 10 Million in your HYPED article.

Hey Frank...the article is actually very factual and to the point. There is nowhere in the article where it metions "impending doom". Its just observations and research and these are there findings. Anyone who would freak out over this are the ones who take it as "hype".
