Rocks stretch, break, and flow, depending on how and under which conditions they are loaded. A new formulation to better capture Earth’s rheology is explored in the context of plate thickness.
Earth’s faults slip most catastrophically as earthquakes. The rise of geodesy reveals an array of slower slip events, meaning faults are nearly always active. Are these behaviors really so different?
A comparison of deformation rates from Canada’s Saint Lawrence Valley offers compelling evidence that strain in the region is concentrated along ancient structures from previous tectonic cycles.
Different nucleation styles detected in five slow-slip events in the same area of Japan’s Ryukyu subduction zone suggest the physical properties along this tectonic plate interface change over time.

For the first time, scientists use GPS to measure the displacement rate of the subducting Pacific Plate near the source of disastrous shaking in 2011.
Researchers examined the crustal deformation associated with earthquakes that occurred before the 2011 Tohoku-oki earthquake.
