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

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 ...

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

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 ...

Newly-released research led by the University of Washington (UW) showed that a feature scientists hypothesized was present ...

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 ...

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 ...

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.

Earthquakes are measured in magnitude, which determines their size. The greater the number, the larger and more powerful the earthquake. Live updates: 4.8 magnitude earthquake rattles NYC, New Jersey ...
