A small team of geologists and seismologists at the California Institute of Technology has found evidence via computer modeling that suggest giant blobs of material near the Earth's core, believed to ...

The dance of the continents has been reshaping Earth for billions of years, creating the landscapes we walk on today. Scientists are unlocking secrets about how plate tectonics forged our modern world ...

The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated ...

Geophysical observations and computer simulations suggest that a tectonic plate segment is delaminating in the area that generated a large earthquake that destroyed Lisbon in 1755. This rare oceanic ...

Earthquakes usually occur along fracture zones in Earth's crust, where large tectonic plates slide past one another and become locked. Stress builds up over long periods and is suddenly released in ...

A new study makes the case that the solar system’s hellish second planet once may have had plate tectonics that could have made it more hospitable to life. By Kenneth Chang Venus today is not like ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

The presence of offsets, appearing at intervals ranging from 10s to 100s of kilometres, is a distinct characteristic of constructive tectonic plate margins. By comparison, boundaries associated with ...
