Sandwiched between tectonic plates are layers of material that show up as thin shadows on seismic tomography, a kind of CT scan of the Earth. For years, scientists assumed the anomalies were signs of highly pressurized water squeezed into densely packed rock and that the fluid acted as a kind of hair-trigger on earthquake faults.… Continue Reading Are Deep Fluids Behind the Largest Earthquakes? ‘Not So Fast!’ Says UT Graduate Student

But what happens when a plate disappears into the planet’s interior? The question has long puzzled scientists because conventional wisdom said that sinking… Continue Reading Fate of Sinking Tectonic Plates is Revealed
