A team from ETH Zurich has discovered solid rock flowing 1,700 miles beneath the Earth’s surface, which supports the theory of convection currents similar to boiling water. This movement may explain the processes driving natural phenomena like earthquakes and volcanoes. Lead researcher Professor Motohiko Murakami notes that the research centers on the D' layer of the mantle, where unconventional seismic wave acceleration occurs. The findings reveal how the mineral post-perovskite transforms under pressure, leading to its unique hardness and furthering our understanding of Earth's inner dynamics.
This discovery shows that the Earth is not only active on the surface, but is also in motion deep inside, confirming the convection currents theory.
In our investigation into the D' layer, we realized that the sudden speeding up of seismic waves was due to the unique properties of post-perovskite.
