This gradual accumulation and release of stress and strain is now referred to as the "elastic rebound theory" of earthquakes. Most earthquakes are the result of the sudden elastic rebound of ...

When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is ...

This map models locking at the Cascadia Subduction Zone, with red showing where the plates are tightly locked and orange/yellow indicating less locking. The study sites are marked with small red ...

At the Cascadia subduction zone in the Pacific Northwest, one tectonic plate is moving underneath another. New experimental work at UC Davis shows how rocks on faults deep in the Earth can cement ...
