Addis Ababa, May 3, 2025 — In a revolutionary series of geological studies, researchers from the U.S. Geological Survey (USGS), alongside local geoscientists, have unveiled alarming revelations about the escalating geological activity within the East African Rift System. This intensifying rift could dramatically alter the landscape of the African continent and give rise to a new ocean.

This remarkable tectonic process is unfolding across a vibrant area, including Ethiopia, Djibouti, and Eritrea, where the Somalian tectonic plate gradually drifts away from the Nubian plate. This pivotal shift occurs in tandem with the separation of both plates from the Arabian plate. This divergence is measured at approximately 0.3 inches (7 mm) each year, accelerated by vigorous magma activity surging from the mantle beneath the Earth’s crust. This molten rock exerts tremendous pressure, leading to the formation of rifts.

In recent times, the surge in tectonic movements has sparked a dramatic increase in seismic activity throughout the region, prompting local communities to grapple with more frequent and intense earthquakes, some of significant magnitude, and volcanic eruptions that endanger lives and damage infrastructure. Scientists warn that if this rifting continues unchecked over millions of years, it could widen sufficiently for waters from the Indian Ocean to flood the rift valley, ultimately creating a new ocean and severing the Horn of Africa from the mainland.

“This is one of the most extraordinary geological sites on Earth, allowing us to observe an active continental rift in its early stages,” stated Dr. Cynthia Ebinger, a leading geologist and expert on the area. “It offers an unparalleled opportunity to probe the Earth’s dynamic interior and understand the powerful forces driving tectonic activity.”

While the complete emergence of a new ocean is a prospect set to unfold over a staggering 1 million to 20 million years, scientists are leveraging cutting-edge satellite imaging and GPS technology to monitor tectonic shifts with remarkable accuracy. They track even the slightest alterations in the landscape, revealing the profound geological processes. As a result, the region has evolved into a natural laboratory, providing vital insights into plate tectonics and the long-term geological evolution of our planet.

Though forming a new ocean may be a distant vision, the immediate threats posed by this tectonic activity have profound implications for local populations. As infrastructure development and urban planning progress, stakeholders must integrate the heightened risks of earthquakes and ground instability associated with these geological changes. Therefore, local communities face a dual challenge: navigating an evolving landscape that holds both the potential for opportunity and the looming risks of disruption.
