As PG&E’s aging Diablo nuclear power plant is up for a license renewal, one scientist cites new GPS data to suggest there’s a looming seismic threat.

Riverside continues with surface exploration in advance of the mid-August diamond drill program. The key finding of the work to date has been the identification of stacked thrust faults in the ...

Fractures in the ground can be mysterious. The 1994 Northridge quake occurred on an unknown blind thrust fault that never extended to the surface and hadn’t been mapped.

Knowledge 3 main types of fault lines and how they form earthquakes Faults are classified into three main types: normal, reverse, and strike-slip faults.

Given the depth and location, the shallowly dipping thrust fault at the plate interface is the more likely source. This event was primarily caused by subduction zone activity in the region.

Deciphering tectonic evolution: Discrete element modeling reveals mechanism of the Qiyueshan Fault within the Xuefengshan foreland thrust belt, South China ...

The 2004 Aceh Earthquake and Tsunami was one of the biggest natural disasters in history. This tragedy provided important lessons for improving disaster risk mitigation.

A 4.4 magnitude earthquake in Los Angeles in August was along the Puente Hills fault system, a thrust fault that runs beneath one of the city's oldest and most densely populated areas.

The faults in Irish Hills near the plant are capable of generating large earthquakes approximately every 715 years. PG&E’s study neglects the possibility of an offshore thrust fault that could trigger ...

The Puente Hills fault system is back in focus after a 4.4-magnitude earthquake near Highland Park. It is one of several similar faults in the Los Angeles Basin.
