On a Remote Island, a Lost Part of the World Is Found
On a small volcanic island in the Indian Ocean lies a geologic enigma—a mass of pure white quartzite sandstone apparently formed on a faraway continent long ago. How did it get there?

Learning from Slow-Slip Earthquakes
Off the coast of New Zealand, there is an area where earthquakes can happen in slow-motion as two tectonic plates grind past one another. These slow-slip events create an ideal lab for studying fault behavior along the shallow portion of subduction zones.

The Plate Tectonics Revolution: It Was All About the Data
The young scientists who led the plate tectonics revolution 50 years ago showed how asking the right questions and having access to a wide range of shared data could open doors to an entirely new understanding of our planet.

Walter Pitman and the Smoking Gun of Plate Tectonics
“We had this magic key, this magic magnetic profile,” Pitman said. “We were able to date it and eventually use it not only as a tool that proved continental drift but a tool by which we could actually reconstruct the pattern of drift, that is the relative position of the continents, and the actual timing…
