'10,000 billion gallons': Earth’s sixth ocean is forming and many countries are at risk of vanishing

Produced by: Mohsin Shaikh

Tectonic Movements

The African continent is undergoing a slow, monumental split due to tectonic plate movements in the Afar Triangle. A new ocean may form millions of years from now, reshaping global geography and ecosystems.

Rift Formation

The East African Rift system, marked by the Nubian, Somali, and Arabian plates, is the epicenter of this shift. A 35-mile rift in Ethiopia, formed in 2005, exemplifies this ongoing geological process.

Mantle Plume

A plume of super-heated rock rising from the mantle below East Africa is driving the rift. This geological force causes the crust to break, forming valleys and triggering volcanic activity.

Volcanic Insight

Ethiopia’s Erta Ale volcano offers clues into active tectonic processes, similar to mid-ocean ridges. GPS and satellite radar reveal ground movements, with African plates separating at up to 0.5 inches per year.

Human Displacement

Over 15 million Africans are already displaced due to climate-related changes, per UNEP. The rift’s progression could lead to further displacement, forcing communities to migrate as landmasses destabilize.

Ecological Impact

The shifting tectonics will displace flora and fauna, threatening biodiversity. Habitats will vanish or transform, impacting Africa’s ecosystems as the continent slowly divides.

Economic Potential

A new ocean could unlock economic opportunities for landlocked nations like Uganda and Zambia, offering new coastlines, ports, and trade routes that redefine regional commerce.

Marine Diversity

The sixth ocean’s emergence will foster unique marine ecosystems and biodiversity, creating new avenues for scientific research into ocean evolution and ecological adaptation.
