Unexpected Elements
Celebrating Science on Africa Day

And I told them, hey, hold on.

Unexpected Elements
Celebrating Science on Africa Day

In fact, there's a research that's suggesting that East Africa may actually be splitting apart.

Unexpected Elements
Celebrating Science on Africa Day

And, you know, researchers are saying that this is happening faster than scientists once believed.

Unexpected Elements
Celebrating Science on Africa Day

So the forecast now we had to talk about Turkana region, and this is in the northern Kenya.

Unexpected Elements
Celebrating Science on Africa Day

It's an area where geologists now think could be one of the weakest points in the Earth's crust.

Unexpected Elements
Celebrating Science on Africa Day

So that was an interesting conversation.

Unexpected Elements
Celebrating Science on Africa Day

Okay, so I've had colleagues hike through Turkana to try and find the, I think they're building a geothermal power station up there, yeah?

Unexpected Elements
Celebrating Science on Africa Day

Yes, yes.

Unexpected Elements
Celebrating Science on Africa Day

Phyllis, is it part of the Rift Valley?

Unexpected Elements
Celebrating Science on Africa Day

It is.

Unexpected Elements

So the Turkana region is far northwest part of Kenya.

Unexpected Elements
Celebrating Science on Africa Day

It is near the border with Uganda and South Sudan and also Ethiopia.

However, as you may know, generally East Africa itself sits on a huge tectonic boundary.

Unexpected Elements
Celebrating Science on Africa Day

So the ground beneath Eastern Africa is gradually stretching.

Unexpected Elements
Celebrating Science on Africa Day

It's thinning and it's cracking as two tectonic plates now drift away from each other.

Unexpected Elements
Celebrating Science on Africa Day

OK, so tectonic plates, these are enormous plates of earth, I guess, on which we all sit and there are the cracks between the plates and the plates are either pushing towards each other or grinding against their neighbour in an unsexy way, which makes earthquakes.

Unexpected Elements
Celebrating Science on Africa Day

And the big tectonic boundary in Africa is where these two plates are moving apart, right?

Unexpected Elements
Celebrating Science on Africa Day

Yeah.

Unexpected Elements
Celebrating Science on Africa Day

Yes, you've described it perfectly.

Unexpected Elements

So essentially the African continent is dividing along two massive tectonic plates.
