In the spring of 2005, a crack appeared in the Ethiopian desert almost overnight.<\/p>\n
It stretched for 35 miles in just a few days, splitting the ground so fast that local herders watched it happen.<\/p>\n
Scientists who flew in to measure it had never seen anything like it at the surface.<\/p>\n
Cracks like it are usually the work of ages, not a single week.<\/p>\n
That crack was not a freak event<\/strong>.<\/p>\n It was a glimpse of something that has been building for 30 million years<\/strong>.<\/p>\n The East African Rift runs for roughly 3,700 miles, from Ethiopia south toward Mozambique.<\/p>\n Along its length, two huge sections of the African continent are being pulled in opposite directions.<\/p>\n The slow churn of hot rock deep in the mantle is driving them apart.<\/p>\n The movement is only about one inch per year.<\/p>\n You could not feel it shift if you stood right on top of it.<\/p>\n That sounds trivial until you learn it has been happening since before our earliest ancestors walked upright.<\/p>\n In the stretch crossing Kenya and Ethiopia, the ground has already dropped in places.<\/p>\n It has formed a long sunken valley flanked by steep walls hundreds of feet high.<\/p>\n That valley is not just scenery<\/strong>, it is the first chapter<\/strong> of something enormous.<\/p>\n Most people picture an ocean forming as water rushes in from somewhere else.<\/p>\n The real process is the opposite, the land tears apart first.<\/p>\n It drops lower and lower, and only much later does the sea find the gap.<\/p>\n Geologists compare East Africa now to the Atlantic about 200 million years ago.<\/p>\n Back then there was no Atlantic, only a widening crack in a single supercontinent.<\/p>\n That crack became a rift, the rift became a shallow sea, and the sea became an ocean.<\/p>\n East Africa sits at the earliest stage of that same story.<\/p>\n In time its rift floor could fill with water and become a brand new ocean<\/strong> that reshapes the whole map<\/strong>.<\/p>\n Because the rift has been slowly sinking for millions of years, it acted as a natural trap.<\/p>\n Sediment, ash, and the remains of animals settled into it and were sealed away.<\/p>\n That is why this valley holds one of the richest fossil records on Earth.<\/p>\n Few places pack so much of our own deep story into one stretch of ground.<\/p>\n According to one review<\/a>, the Turkana Rift alone has yielded more than 1,200 fossils<\/strong> of human ancestors.<\/p>\n That is roughly a third of all such fossils ever found across Africa.<\/p>\n Lucy, the famous 3.2 million year old skeleton, came from a rift site in Ethiopia.<\/p>\n Turkana Boy, one of the most complete early skeletons, came from the shores of Lake Turkana.<\/p>\n The same forces splitting Africa apart also preserved our ancestors<\/strong> below the surface.<\/p>\n Beneath the rift, a massive plume of hot rock is pressing upward against the base of the crust.<\/p>\n It domes the land upward before pulling it apart from below.<\/p>\n This is the same process that built Iceland in the middle of the Atlantic.<\/p>\n In East Africa the plume is so large that it has spawned two separate rifts.<\/p>\n The Eastern Rift runs through Ethiopia and Kenya, and the Western Rift curves through Uganda and Tanzania.<\/p>\n Where the two arms meet in the south, the continent will one day fully separate<\/strong>.<\/p>\n The Horn of Africa, and everything east of the rift, will drift off as its own landmass.<\/p>\n That new continent would carry its own coastline and its own weather.<\/p>\n It would become a brand new continent<\/strong>, riding a fresh ocean between itself and the rest of Africa.<\/p>\n The 2005 rupture in Ethiopia was not a one time moment.<\/p>\n Since then, geologists have recorded hundreds of smaller earthquakes along the rift each year.<\/p>\n Erta Ale, a nearby lava lake, has stayed active for more than a century.<\/p>\n The ground in parts of the region has dropped by as much as 20 feet in intense events.<\/p>\n According to one account<\/a>, villages near the rift have had to move as fissures opened beneath them.<\/p>\n For the people living along this fault, the geology is not abstract at all.<\/p>\n It shakes their homes and reshapes their land within a single lifetime.<\/p>\n Yet the bigger picture is one of remarkable creation<\/strong>, echoed in other hidden worlds like an ice core<\/a> and a NASA find<\/a>.<\/p>\n A new ocean arrives one inch a year, one crack at a time, on a planet still reinventing itself<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" In the spring of 2005, a crack appeared in the Ethiopian desert almost overnight.
