Iberian Peninsula Slowly Rotating Due to Tectonic Forces, Geologists Say
The ground beneath Portugal and Spain may feel immovable, but scientists say the entire Iberian Peninsula is undergoing a subtle geological rotation a movement so slow it can only be detected with precision instruments.
Using long-term GPS monitoring and satellite measurements, researchers have identified millimeter-scale shifts across the peninsula. These movements indicate that Iberia is behaving like a semi-rigid tectonic block, gradually pivoting as powerful forces build along its edges.
Caught Between Two Plates
The slow twist is driven by pressure between the African Plate and the Eurasian Plate. As the African Plate creeps northward and collides with Eurasia, stress accumulates along fault zones, particularly near the Azores–Gibraltar fracture zone off s...
