About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

Geoscientists from the University of Toronto have made a breakthrough discovery that adds new dimensions to the theory of plate tectonics. Their research, published in Geophysical Research Letters, ...

Newly published research has revealed that compositional rock anomalies within oceanic plates caused by ancient tectonics influence the trajectory and speed of the plates as they plunge deep into ...

One of the worst earthquakes in European history ripped through Portugal in 1755, causing a tsunami, fires and shaking that killed tens of thousands of people and caused widespread destruction.

The map highlights in yellow the zones of the Pacific Plate that are being pulled apart by the sinking tectonic plate along the Pacific Ring of Fire. TORONTO, ON – New research led by a team of ...

Until now, it has been assumed that the oxygenation of the oceans over geological timescales has mainly been driven by atmospheric oxygen levels. However, a new study published in Nature on June 27 ...

Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy. The work comes from the University of Derby, led by Dr. Jordan Phethean. His ...
