The 8.8 magnitude quake off Russia that triggered tsunami warnings across the Pacific occurred on what is known as a ...

Earthquake scientists rely on distant seismic instruments to infer how faults rupture during large earthquakes. This video ...

The 8.7 magnitude quake, followed by a 8.2 magnitude aftershock, could signal the formation of a new plate boundary under the Earth. While not the largest earthquakes ever recorded, the two quakes ...

Plate tectonics Kattenhorn and Prokter think this phenomenon of one plate sliding under another, which is known as subduction, is the most likely explanation for the disappearing puzzle piece.

At the intersection of the two plates, called a plate boundary, the seafloor of the Nazca is pushing under South America at a rate of about 2.5 inches a year.

The heat flow at convergent plate boundaries is in turn influenced by the frictional energy at the interfaces of the continental plates. One can imagine the formation of mountains using a tablecloth.

The estimate is 50% of plate tectonic movement is driven by this heat, and about 20 terawatts of heat flows between the core and the mantle. That's just slightly more than the average total power ...

At north, widely recognized plate boundary (Sorol Trough) did not seem to extend to the Yap Trench. “We may hold the key to evolution of Caroline Plate after its oceanic spreading,” Zhang says.

It marks the boundary where two tectonic plates fused together and an ancient ocean disappeared. Our team of geologists traveled here to collect rocks that erupted as lava more than 60 million ...
