The scientists found that an earthquake that initiates on one thrust fault can spread 10 times farther than previously thought to a second nearby thrust fault, vastly expanding the possible range ...

The quake ruptured on a small section of a fault associated with the Puente Hills thrust fault system, which has long been cited as a major seismic hazard for Southern California because it runs ...

Scientists thought the Wilmington blind‐thrust fault that runs deep under the Los Angeles region had been dormant since the Late Pliocene era, millions of years ago. But a new study reveals that ...

The 4.4 magnitude earthquake that was felt in many Southern California cities Monday fell on the Puente Hills Thrust Fault System, which is potentially the most destructive in the region.

Seismologist Lucy Jones, a Caltech research associate, said the earthquake, centered in the Eastside neighborhood of El Sereno, occurred on the Puente Hills thrust fault system. It’s the same ...

The Puente Hills thrust fault runs beneath downtown Los Angeles and Orange County – two highly populated areas. The 10-mile deep fault angles like a ramp and gets closest to the surface near the ...

A new study shines a light on a system of earthquake faults in the San Francisco Bay Area that most residents don’t even know exists. The Foothill Thrust Belt faults are deep under Silicon ...

That particular quake and most of the region's devastating quakes happened about 100 miles northwest of Tuesday's earthquake on what's known as a "thrust fault" where the two plates meet.

Monday’s 4.4 magnitude earthquake near Los Angeles’ Highland Park neighborhood occurred along the Puente Hills Fault, also known as the Puente Hills Thrust Fault system. This 25-mile-long ...

The 2004 Indian Ocean earthquake off the coast of Banda Aceh, Indonesia, was caused by a thrust fault: a tectonic plate that was sliding beneath an adjacent plate moved suddenly, forcing that ...

Monday’s 4.4 magnitude earthquake near Los Angeles’ Highland Park neighborhood occurred along the Puente Hills Fault, also known as the Puente Hills Thrust Fault system. This 25-mile-long ...
