It sits near a boundary where the African and Eurasian tectonic plates push and slide, building stress that can be released as earthquakes.<\/p>\n\n\n\n
What subduction means<\/h2>\n\n\n\n
Earth\u2019s outer shell is broken into huge slabs of rock called tectonic plates. They move slowly, but when they collide, one can be forced downward.<\/p>\n\n\n\n
Subduction<\/a> happens when one plate bends and sinks under another and slides down into Earth\u2019s interior. That sinking edge can trigger earthquakes, feed volcanoes, and recycle old seafloor back into deeper layers.<\/p>\n\n\n\nMost of the Atlantic today is not built around subduction. Instead, it is a spreading ocean, where new crust is created along the Mid-Atlantic Ridge, and its edges are mostly quiet compared with the Pacific.<\/p>\n\n\n\n
Inside the new computer model<\/h2>\n\n\n\n
The new research used 3D computer simulations that try to recreate how rock moves deep underground over long periods. The team spans the University of Lisbon Faculty of Sciences, the Instituto Dom Luiz, and Johannes Gutenberg University Mainz<\/a>.<\/p>\n\n\n\nTheir simulations are \u201cgravity-driven,\u201d meaning dense slabs can sink and pull on the rest of the plate, a bit like a heavy curtain sliding off a table. In practical terms, that helps test whether Gibraltar\u2019s sluggish subduction could wake up again after a long pause.<\/p>\n\n\n\n

Subduction initiation matters because it is the turning point when an ocean stops expanding and starts being recycled back into the mantle.<\/p>\n\n\n\n
A long countdown, not a near-term collapse<\/h2>\n\n\n\n
So why do some descriptions make it sound like the strait is about to vanish? In geology, \u201csoon\u201d can mean tens of millions of years, and this study\u2019s estimate is about 20 million years before Gibraltar\u2019s subduction pushes farther into the Atlantic.<\/p>\n\n\n\n
The researchers describe this jump as \u201csubduction invasion.\u201d Put simply, a subduction zone that formed in a closing ocean, like parts of the Mediterranean, may migrate into a still-growing ocean, like the Atlantic.<\/p>\n\n\n\n
There is also a key caveat. The authors stress that it is hard to create new subduction zones because oceanic plates are strong and resist snapping and bending, and that is why they built models to test what could overcome that resistance.<\/p>\n\n\n\n
Why the Atlantic matters<\/h2>\n\n\n\n
Subduction zones are where the biggest quakes and many volcanic arcs are born. The Atlantic has far fewer obvious subduction zones than the Pacific, so scientists pay close attention to any place where a new one might be starting.<\/p>\n\n\n\n
In the press materials<\/a>, the lead author called the Atlantic crust here \u201csuper strong and rigid.\u201d The model argues that this strength helps explain why the Gibraltar system can get stuck in a slow phase instead of breaking off and stopping.<\/p>\n\n\n\nIf the process continues, it could be an early step in the Atlantic entering a new stage of its life. That does not mean the ocean is about to \u201cshut,\u201d but it does suggest the boundary conditions are changing along its eastern edge.<\/p>\n\n\n\n
Could an Atlantic Ring of Fire form?<\/h2>\n\n\n\n
The Pacific Ring of Fire is a horseshoe-shaped belt about 24,900 miles long, marked by frequent earthquakes and volcanoes. The study raises the long-range possibility that a similar chain could eventually develop around parts of the Atlantic.<\/p>\n\n\n\n
Still, the word \u201ceventually\u201d is doing a lot of work here. The models described a new subduction system forming over tens of millions of years, which is far beyond any human planning horizon.<\/p>\n\n\n\n
A future Atlantic version, if it ever formed, would likely grow piece by piece as new subduction segments turned on and linked up. For now, researchers treat it as a hypothesis worth testing, not a forecast for the next few centuries.<\/p>\n\n\n\n![\"Aerial](\"https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/03\/strait-of-gibraltar-geology-subduction-atlantic-ocean-study.jpg\" "\\"\\"")
