Impact: The 1933 earthquake was Southern California’s deadliest in the modern record, leaving nearly 120 dead and causing $40 ...

Monday’s magnitude 4.4 quake that rattled Southern California is believed to have struck on a well-known and dangerous fault system known as the Puente Hills thrust fault system.

A California fault line remains relatively unknown. It caused last week’s quake and might be the site of ‘the big one’ - The 10-mile deep Puente Hills thrust fault runs beneath downtown Los ...

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.

Therefore, while the San Andreas fault may generate more powerful earthquakes—up to magnitudes of around 8.0 or even higher—the location of the Puente Hills thrust fault makes it a major hazard.

Thrust, or reverse, faults are features in the Earth’s crust that occur when a massive slab of rock moves up and over a lower block of rock, which moves deeper into the Earth, Aron explained.

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 ...

One young thrust fault scarp, located within the de Gerlache Rim 2 Artemis III candidate landing region, is modeled and shows that the formation of this fault scarp could have been associated with a ...

The Puente Hills thrust fault is the same overall fault network that produced the Whittier Narrows – which measured a 5.9 magnitude, killed eight people and caused some $358 million in damage in ...
