As observed in Lesson 3, at low pressures and temperatures rock is a brittle material that will ... the break is referred to as a fault. Earthquakes are associated with displacements on faults.

Caltech researchers have developed a new method to study Earth's structure deep beneath the surface, at the boundary between ...

Instead, there are abrupt changes in rock friction during the transition to semi-brittle behavior. "This means we need to rethink the fundamental basis of the fault mechanics used in forecasting ...
