Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Earthquakes on the Puente Hills thrust fault could be particularly dangerous because the shaking would occur directly beneath LA's surface infrastructure.

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.

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.
