Learn how seismic waves helped identify rare mantle earthquakes deep below Earth’s crust, offering new insight into the ...

A rare type of deep underground earthquake occurring in the Earth’s mantle has finally been isolated and mapped by Stanford researchers.

A study of the East African Rift reveals that ancient heating and dehydration can strengthen continental crust, reshaping how and where continents break apart.

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year. Subduction and the formation of continents, a ...

Using an unprecedented amount of high-resolution satellite data, researchers have found that Earth’s fault lines are far weaker—and continents far less rigid—than long-standing geological models ...

Fresh evidence suggests early Earth wasn’t locked under a rigid stagnant lid but was already experiencing intense subduction. Ancient melt inclusions and advanced simulations point to continents ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...
