Earth surface is covered with rigid plates that move, crash into each other and dive into the planet's interior. But when did ...

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.

Russia's massive quake has already triggered at least 10 aftershocks, and could continue for months, according to scientists.

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 ...

A mysterious layer lies beneath Earth's massive tectonic plates. Sandwiched between two rock layers — the rigid lithosphere and the more pliable asthenosphere — this thin boundary is like the ...

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 ...

Weather Blog Here's how plate tectonics caused Puerto Rico's recent earthquakes The island sits where the Caribbean Plate meets the North American Plate, an area that can be very active.

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.
