By contrast, an earthquake on the Puente Hills thrust fault system probably would max out at a magnitude 7.5 — still powerful, but less so than the southern San Andreas.

The magnitude 4.4 earthquake that rattled Los Angeles on Monday was centered within one of the region’s most potentially destructive fault systems, one capable of producing a magnitude 7.5 ...

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.

While California’s 750-mile-long San Andreas Fault is notorious, experts believe a smaller fault line possesses a greater threat to lives and property in the southern part of the state.

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 ...
