The researchers theorize that these far-off remnants could either be deposits of silica-rich material that have hung around since the formation of the mantle four billion years ago, or areas where ...

In a nutshell Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme ...

Plates at subduction zones typically move just a few centimeters per year. But when accumulated stress at these convergent plate boundaries releases suddenly, the plates can slip several meters and ...

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

These fragments of our surface do have a tendency to sink into Earth's mantle when they lose out in the plate-on-plate collision known as subduction, but when this happens, these terrestrial ...

Amid Earth’s mobile tectonic plates, subduction zones arise as regions of intense geological activity and concentrate minerals into ore deposits like gold.

A new way of measuring structures deep inside Earth has highlighted numerous previously unknown blobs within our planet's ...

These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found ...

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 ...

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

Oregon scientists are hoping to help the coastal communities survive a major inundation in various ways. One of those is ...

SNOQUALMIE, Wash. — An earthquake struck near Snoqualmie Monday afternoon, according to the United States Geological Survey ...
