00:00East Africa's Great Rift, a continent slowly splitting apart.
00:05A cracked desert floor stretches across Ethiopia's Afar Triangle.
00:09East Africa's rift pulls plates apart, opens valleys, and may invite seawater millions of years from now.
00:16The Nubian Plate and Somali Plate separate beneath Ethiopia, where stretched crust breaks into long fault lines.
00:24The Arabian Plate pulls away near the Red Sea, leaving Afar's triple junction split by three moving edges.
00:32Erta Ale Volcano glows red at night, while molten rock rises through thin crust under the desert.
00:39Afar's salt flats bake under white heat, and jagged cracks cut roads, lava fields, and dry ground.
00:46Geologists track tiny earthquakes across Ethiopia and Kenya using sensors that record rock breaking far below.
00:52GPS stations measure ground motion by millimeters and centimeters, showing East Africa stretching slowly year after year.
01:01Lake Turkana reflects rift walls in Kenya, where steep escarpments mark the continent's pulled-apart crust.
01:08The Red Sea and Gulf of Aden already hold seawater, where Arabia separated from Africa.
01:13In future ages, sinking land could let ocean water flood parts of the East African rift.
01:20Volcanoes, earthquakes, salt flats, and rift lakes show a continent changing without a single, sudden tear.
01:28A red lava glow burns under black sky, while Africa slowly opens beneath the desert.
