Scientists warn several regions face massive risk.

Across the United States a handful of seismic zones are drawing intense attention from researchers who track the quiet shifts beneath our feet. These regions sit over faults capable of producing quakes far stronger than the everyday tremors people occasionally feel. Their histories reveal long intervals of silence followed by destructive bursts that reshape entire landscapes. As scientists map these dangerous zones with new tools, the urgency around future risk grows sharper, and the states lying above them face questions they can no longer ignore.
