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 ...

The different styles of faulting can also combine in a single event, with one fault moving in both a vertical and strike-slip motion during an earthquake. All faults are related to the movement of ...

When there is too much friction between the fault lines, energy is released suddenly, triggering seismic waves which lead to an earthquake.

While it is worth knowing all the different types of earthquakes ... many of those along the San Andreas Fault. As a reference point, most people feel earthquakes starting at a magnitude of ...

Its findings reveal that different underlying mechanisms affect the frictional resistance of faults, challenging a common understanding of seismic activity ... on various rock types, including ...

Earthquakes all spring from faults deep underground, but what kind? The impact and severity of each quake depends on the answer to that question. (Learn more about earthquakes.) Most earthquakes ...

A recent study from Utah State University geoscientists explores the characteristics of rocks from a fault zone in Utah.

the energy they release into the Earth is comparable to powerful earthquakes. "It has become apparent only in the last few years that slow slip events happen at many different types of faults, and ...

About 100 scientists, all different types of earth scientists, got together. We identified the active faults. And then we looked at the history of past movement, past earthquakes on those faults ...

Earthquakes occur along fault lines between continental plates ... The rock layers themselves along this fault line are a mixture of different types of rocks. The region the researchers examined ...

We all have our faults, and that includes planet Earth. Earthquakes, big and small, rattle the globe every day, most recently making news this week with temblors in northern California.
