Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird ...

A tsunami struck a fjord in East Greenland in 2023, ringing seismometers for nine straight days. A new satellite study ...

Seismic waves accelerate in the D" layer, about 2,700 km deep, due to the alignment of post-perovskite crystals, which occurs as solid mantle rock flows horizontally under extreme pressure and ...

Something unusual is happening deep within Earth’s mantle,around 1,700 miles below the surface, where seismic waves accelerate in a way that has left scientists scratching their heads for decades.
