New geophysical research proposes that the Cascadia subduction zone and the San Andreas fault may be mechanically linked, allowing one quake to trigger the other within minutes or hours. This “synchronization” could turn a single major earthquake into a multi‑region disaster on the U.S. West Coast. Scientists warn that emergency planning should consider the possibility of near‑simultaneous shocks.
