Slow earthquakes occur continuously in the Alaska-Aleutian subduction zone

Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that "slow earthquakes" are...

Rapid uplift of Southern Tibet

Using seismic data and supercomputers, Rice University geophysicists have conducted a massive seismic CT scan of the upper mantle beneath the Tibetan Plateau and...

Geology and biology agree on Pangaea supercontinent breakup dates

Scientists at The Australian National University (ANU) have found that independent estimates from geology and biology agree on the timing of the breakup of...

The birth and death of a tectonic plate

Several hundred miles off the Pacific Northwest coast, a small tectonic plate called the Juan de Fuca is slowly sliding under the North American...

Supercomputing helps researchers understand Earth’s interior

Contrary to posters you may have seen hanging on the walls in science buildings and classrooms, Lijun Liu, professor of geology at Illinois, knows...

As continents continue moving, study suggests effects on biodiversity

Continental drift and plate tectonics—the notion that large chunks of Earth's crust slowly but inexorably shift positions—was proposed in 1912 but not accepted until...

Stirring things up in the Earth’s mantle

New insights into the convection patterns of the Earth's mantle and its chemical makeup have been revealed by a researcher from the University of...

Changes in tectonic activity may have shaped composition of Panama Canal...

Changes in the composition of magma may have caused variations in the Panama Canal volcanic rock formations, according to a study published May 10,...

New timeline proposed for plate tectonics

Earth's history should include 'pre-plate tectonic' and 'plate tectonic' phases beginning less than a billion years ago, according to a team of geoscientists in...

Continental crust thanks to the right mixture

For the first time, ETH scientists have successfully recreated the formation of continental crust in the Archean using a computer simulation. The model helps...
