NORFOLK, Va. — Fault lines are fractures or breaks in the Earth's crust where tectonic plates move past each other, often resulting in earthquakes. These geological features are classified into three ...

CORVALLIS, Ore. - Big earthquakes appear to follow a brief episode of "shallow mantle creep" and "seismic swarms," suggests new research at Oregon State University that offers an explanation for the ...

A recent study has revealed extensive data on how strike-slip faults develop over time and eventually cause earthquakes at the Earth's surface. Researchers coined the movement of two plates in a ...

AMHERST, Mass. - Structural geologist Michele Cooke calls it the "million-dollar question" that underlies all work in her laboratory at the University of Massachusetts Amherst: what goes on deep in ...

The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. It forms the tectonic boundary between the Pacific Plate and the North ...

CORVALLIS, Ore. (KOIN) — Big earthquakes appear to follow a brief episode of “shallow mantle creep” and “seismic swarms,” according to new research at Oregon State University. The study was published ...

One structural geologist calls it the 'million-dollar question' that underlies all work in her laboratory: what goes on deep in the earth as strike-slip faults form in the crust? This is the fault ...
