A 6.6-magnitude earthquake struck far off southwest Australia on Wednesday, but no tsunami warning was issued. The epicenter was in the Indian Ocean 2,069 kilometers (1,283 miles) southwest of Albany on the southwest tip of Western Australia state at...
New Curtin-led research has revealed that water played a far bigger role than previously thought in shaping Earth's first continents, transforming the planet's early crust and helping to build the landmasses we see today. In an article published in Communications...

New step in tectonic squeeze that turns seafloor into mountains

Scientists use tiny minerals called zircons as geologic timekeepers. Often no bigger than a grain of sand, these crystals record chemical signatures of the...

Plate tectonic surprise: Geologist unexpectedly finds remnants of a lost mega-plate

Utrecht University geologist Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the...

Plate tectonic surprise: Geologist unexpectedly finds remnants of a lost mega-plate

Utrecht University geologist Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the...

Earth’s crust, tectonic plates gradually formed, geoscientists find

The Earth's crust continued a slow process of reworking for billions of years, rather than rapidly slowing its growth some 3 billion years ago,...

Scientists investigate tectonic plate boundary earthquake behavior

Renaissance polymath Leonardo da Vinci demonstrated frictional forces slow down the motion of surfaces in contact. Friction, he determined, is proportional to normal force....

New insight into the relationship between slow slip events and the build-up and release of tectonic strain

The Japanese archipelago is actively undergoing seismic shifts due to interactions between the oceanic plate and the continental plate. At the plate boundaries located...

New tectonic plate model could improve earthquake risk assessment

New Zealand is no stranger to earthquakes. Scientists estimate that more than 20,000 occur each year, and the deadliest ones can shudder the entire...

The link between temperature, dehydration and tectonic tremors in Alaska

A Kobe University research group has shed light on how low-frequency tectonic tremors occur; these findings will contribute towards better predictions of future megathrust...

As tectonic plates pull apart, what drives the formation of rifts?

At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from...
