An enormous underwater landslide 60,000 years ago produced the longest flow of sand and mud yet found on Earth. The landslide off the coast of north-west Africa dumped 225 billion metric tonnes of sediment into the ocean in a matter of hours or days.
The flow travelled 1,500km (932 miles) - the distance from London to Rome - before depositing its sediment.
The work, by a British team of researchers has been published in the academic journal Nature.
The massive surge put down the same amount of sediment that comes out of all the world's rivers combined over a period of 10 years.
After blocks from the original landslide disintegrated, the sand and mud travelled hundreds of kilometres suspended in the water, without depositing any sediment on the sea floor that it had passed over.
Dr Talling likened this to avalanches in which the snow travels downslope in huge clouds.
A tiny drop in the sea-floor gradient (from 0.05 degrees to 0.01 degrees) eventually forced the flow to settle into a cohesive mass.
In places, the flow was over 150km (93 miles) wide, spread across the open sea floor.

LOL!
Thanks
Shoot, I should have used html to make it more narrow, lol.
You are quite welcome george!
I’m guessing this was caused by the continental drift, when Africa first split off from the Americas. In other worlds, there was a bit of land-floor spreading before sea-floor spreading got started.
SURE you can!!
In the upper right corner you'll find the PAGE icon.
Press it and see the menu.
Select VEIW SOURCE and you'll get the HTML of the page.
You should then be able to find what you need.
(Sorry SNOPES!)
