A machine-learning approach developed for sparse data reliably predicts fault slip in laboratory earthquakes and could be key to predicting fault slip and potentially earthquakes in the field. The research by a Los Alamos ...

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 ...

A Canadian-German research team have documented a new type of earthquake in an injection environment in British Columbia, Canada. Unlike conventional earthquakes of the same magnitude, they are slower and last longer. The ...

It is 2,250 kilometers long, but only 355 kilometers wide at its widest point—on a world map, the Red Sea hardly resembles an ocean. But this is deceptive. A new, albeit still narrow, ocean basin is actually forming between ...
