Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

For decades, seismologists have worked to understand and predict earthquakes, but forecasting remains elusive. Now, ...

mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of these tectonic plates leads to earthquakes and ...

Tectonic plates move, causing strain energy to build up, and that energy eventually releases in the form of an earthquake. As ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.

In the journal Chaos, researchers in Japan explore the likelihood that Earth’s climate, as affected by solar heat, plays a role in seismic activity. Using mathematical and computational methods, they ...
