全球目前不僅要面對地球暖化的變遷，還要注意地質變化。綜合外媒報導，肯亞本月發生數起地震，蜿蜒數英里的巨大裂縫就這樣憑空出現，這條裂縫將道路硬生生分為兩半，所以當局拚命在裂縫內填滿岩石與水泥，試圖恢復公路的運作。研究人員也預測，幾年間的非洲大陸，可能會分裂成兩半。

據報導，研究人員推測，這道裂縫是索馬利亞板塊（Somali）從奴比安板塊（Nubian）分裂的證據，但這過程是慢慢發生的。地質學家阿賀迪（David Ahede）表示，索馬利亞板塊正以每次2.5公分的速度，與奴安比板塊分離，「這過程發生於地殼深處，無法阻止。」在數百萬年後，現在人們熟知的非洲大陸將分裂成兩半。

A crack in Kenya has sparked fears Africa could be splitting in two
Now tectonic boffins are claiming Africa could split in several million years.

Dr Lucia Perez Diaz, Postdoctoral Researcher at the Fault Dynamics Research Group, London's Royal Holloway, explained how this continental rupture could occur.

Writing for The Conversation she said: “The East African Rift Valley stretches over 3,000km from the Gulf of Aden in the north towards Zimbabwe in the south, splitting the African plate into two unequal parts: the Somali and Nubian plates.

“Activity along the eastern branch of the rift valley, running along Ethiopia, Kenya and Tanzania, became evident when the large crack suddenly appeared in south-western Kenya.”

The active rift zone is currently spreading at a few millimetres per year
The process is known as “continental rifting” and requires huge forces to be exerted on the Earth.

Underneath the crust a “magma plume” forms forcing the crust up and eventually splitting it.

Dr Diaz added: “Eventually, over a period of tens of millions of years, seafloor spreading will progress along the entire length of the rift.

“The ocean will flood in and, as a result, the African continent will become smaller and there will be a large island in the Indian Ocean composed of parts of Ethiopia and Somalia, including the Horn of Africa.”

The active rift zone is currently spreading at a few millimetres per year.

This means that in around 10 million years, a new ocean will emerge as the rip continues to tear East Africa apart.

The Whole of Africa is Cracking Up!
The Earth is an ever-changing planet, even though in some respects change might be almost unnoticeable to us. Plate tectonics is a good example of this. But every now and again something dramatic happens and leads to renewed questions about the African continent splitting in two, writes Lucia Perez Diaz for The Conversation Africa.

Geologists Say Plate Tectonics Are Splitting the Entire African Continent in Two—Can Anyone Stop it?

Things aren't looking good for Kenya right now—the country is literally splitting in two.

Enormous rifts have opened within the ground, that stretch across a large chunk of Kenya's countryside. One such tear, located in Narok County, is 66 feet in length and as much as 50 feet deep at its lowest point.

These rifts are causing a lot of trouble throughout the country, with commuters and supply trucks unable to travel safely without massive delays. One video that shows some of the devastation highlights an area of road that has to be filled in temporarily for the sake of keeping traffic flowing on a busy highway, but the solution is far from permanent, and only allows for a limited number of cars to make the crossing at any given time.

In other areas, conditions are even more terrifying for locals, with families having to abandon their homes out of fear that the rift will spear, swallowing their entire livelihoods whole.



Some scientists believe that this is all caused by a tectonic split, deep under the ground, so any measures that are put into place are only going to provide short-term solutions to the problem at best.

Africa was once upon a time perched upon a single tectonic plate, but this has split into two pieces—the Somalian and Nubian tectonic plates—which are slowly pulling away from each other, creating these rifts. Eventually, the two will separate entirely, and Africa as we know it today will be no more, as East Africa detaches from the rest of the continent.

As if this wasn't enough, there's also a third tectonic plate, the Arabian plate, which is also pulling away along part of this stretch, meaning that the ground in Kenya is being subjected to tectonic forces that are moving in three separate directions. It's hardly surprising that the ground is breaking and cracking under all this pressure.

The good news here is that tectonic plates don't exactly move quickly. The Somalian and Nubian plates split approximately 25 million years ago, and the process of their separation has been going on ever since. It's highly unlikely that this split is going to be completed anytime soon.

That knowledge hardly brings comfort to the people who are currently enduring the ongoing rift issues—Kenya is likely to continue to face these challenges for the foreseeable future, and it's difficult to plan for the future when the ground underneath your feet is literally so unstable that you don't know when a huge chasm is going to open up and engulf your home.

It's also worth noting that some scientists speculate that the natural process of the tectonic split has been exacerbated recently due to increased rainfall in the area, which is eroding the ground soil and providing less protection against earthquakes.

It's not necessarily easy to link this rainfall with man-made climate change, but this new report is yet another bizarre weather anomaly in a time when unusual or irrational storms are becoming more prevalent.

All said, it's not entirely clear what has been causing these rifts to open. Some experts caution against attributing too much of this destruction to tectonic plates if there weren't also accompanying earthquakes and volcanic activity. These chasms could have formed for entirely different reasons.

Whatever the cause, things aren't looking good, and one way or the other, in another 10 million years or so, Africa is going to be broken into pieces whether its inhabitants like it or not.

Giant Crack in Africa Will Create a New Ocean

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

The crack, 20 feet wide in spots, opened in 2005 and 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 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 ocean 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.
