Earth's crust has been 'dripping' beneath Andes Mountains for millions of years

Just like honey slowly dripping from a spoon, parts of the rocky outermost layer of Earth's shell are continuously sinking into the more fluid layer of the planet's mantle over the course of millions of years. Known as lithospheric ...

Novel model of fluid distribution in Cascadia Subduction Zone aids understanding of seismic activity

A novel three-dimensional model of the fluid stored deep in Earth's crust along the Cascadia Subduction Zone provides new insight into how the accumulation and release of those fluids may influence seismic activity in the ...

The epic, 550-million-year story of Uluṟu, and the spectacular forces that led to its formation

Part of the magic of Uluru is the way it tricks your senses. Deep orange by day, at sunrise and sunset it appears to change color, becoming a more vibrant shade of red, and then almost purple.

Novel numerical model simulates folding in Earth's crust throughout the earthquake cycle

Earth's crust is constantly in motion. As tectonic plates that make up the lithosphere shift, pulling apart and crashing into each other, the crust fractures and folds in response. Both faulting and folding play out at fault-bend ...
