The Konya Basin in Central Anatolia, Turkey, is sinking rapidly even though the surrounding Central Anatolian Plateau is rising. New research using satellite GNSS and InSAR data shows the basin surface is actively going down. Meanwhile, the nearby plateau remains high, averaging 1.5 to 2 kilometers above sea level. Scientists combined seismic imaging, gravity tests, and lab experiments to study this unique case. They found that the sinking is not caused by faults or surface movements. Instead, it results from changes deep in the Earth's mantle lithosphere. A dense area of cold rock is sinking beneath the basin, pulling the surface down in a process called a "mantle lithospheric drip." This deep drip causes a circular subsidence centered on the basin. The Konya Basin's crust is about 40 kilometers thick, with some thickening at the edges. Gravity data shows the basin lies up to 280 meters lower than expected from crust thickness alone. This points to deep mantle forces reshaping the land from below. Laboratory models support the idea that such mantle drips can cause local basins to form while the surrounding plateau stays high. The Central Anatolian Plateau has been rising for millions of years due to large-scale lithosphere loss. The new sinking is a later, smaller phase of the same process. This discovery shows how large plateaus like Anatolia can change internally over long times without obvious surface shifts. The study highlights the subtle but powerful role of mantle dynamics in Earth's surface changes.
