Let's get one thing out of the way: The supervolcano below Yellowstone is not going to erupt anytime soon; neither are any of the other similar systems that geologists have identified around the world ...

Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed they had a firm grasp on how these waves revealed the rocky mantle’s secrets ...

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 ...

Papers presented in a special symposium at the joint annual meeting of the Geological and Mineralogical Associations of Canada at St. John's in May, 1974. Tectonic settings for emplacement of ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

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 ...

CHAMPAIGN, Ill. — 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 ...
