Scientists Detect “Pulse” Deep Beneath Africa as New Ocean Slowly Forms
Scientists Detect "Pulse" Deep Beneath Africa as New Ocean Slowly Forms - GreekReporter.com
Researchers in Ethiopia’s Afar Rift reported a deep, rhythmic mantle “pulse” that is slowly tearing Africa apart to form a new ocean basin.

A steady underground pulse has been discovered beneath East Africa, where researchers believe a new ocean is gradually forming.
The rhythmic movement was detected in the Afar region of Ethiopia, a geological hotspot where three giant sections of the Earth’s crust—the Arabian, Nubian, and Somalian plates—are slowly pulling apart. The site, known as the Afar Triple Junction, is one of few places on Earth where the process of continental breakup can be observed on land.
As the plates drift in different directions, the ground in the Afar Triangle is thinning. Over time, scientists predict this stretch of land will submerge below sea level, allowing seawater to rush in and eventually form a new ocean basin connected to the Red Sea.

New findings reshape understanding of Earth’s interior
This pulse movement beneath Africa is likely shaped by a plume of hot material pushing up from deep within the Earth. Unlike a symmetrical fountain, the plume is irregular and affected by its environment, including the thickness and speed of the plates above.
If the researchers’ model is correct, it shows that deep Earth activity is not just a one-way force—it can also respond to surface conditions. This changes how scientists view the connection between Earth’s interior and events like volcanoes, earthquakes, and even the breakup of continents.
Commentary:
Please Note: Scientists estimate that the tectonic plates in this region—the African and Somali plates—are pulling away from each other at a rate of approximately 0.8 centimeters per year. While this movement is slow by human standards, it marks the beginning of a process that could culminate in the creation of a new ocean in about 1 million years, or possibly sooner.(Source: Africa Splits Apart Forming a New Ocean Faster Than Predicted - GreekReporter.com)
Although scientists make this claim, the area is prone to seismic activity and a large earthquake might possibly trigger a catastrophic events submerging the Afar Triangle region.
