A record-breaking deep earthquake registered in May 2015 offshore of Japan likely was not a tectonic event but triggered by a ...

A re-examination of the 2015 Bonin Islands earthquake disproved earlier claims of a record-breaking deep aftershock in the ...

Under the Pacific Ocean, hidden material was discovered in Earth’s mantle. So we have sunken, ancient worlds down there, and ...

New measurements suggest mysterious continent-sized masses in our planet’s lower mantle may be extremely stable features ...

Based on previous geodynamic simulations and seismological results, the researchers inferred that the N-S FVDs at depths of 700–900 km reflect the remnant Pacific lower mantle flow field at ...

The magnitude 7.9 Bonin Islands earthquake sequence, which ruptured deep within the earth near the base of the upper mantle, did not include an aftershock that extended to record depths into the lower ...

"The occurrence of ringwoodite together with the hydrous phases indicate a wet environment at this boundary," a team of ...

Geophysicists find areas that resemble the results of tectonic plate collisions — far from any area of such activity.

One previous study of the Bonin Islands earthquake reported a foreshock sequence for the event, while a second study detected a potentially record-breaking deep aftershock in the lower mantle.
