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 ...

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 ...

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 ...

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 ...
