Big earthquakes can trigger other quakes thousands of kilometers away and decades later, according to calculations presented on page 1245 of this issue of Science. The researchers simulated how stress travels through deep, viscous rock and found that the great earthquakes that struck the far North Pacific in the 1950s and `60s could have set off a slow-moving stress wave that triggered a pulse of seismic activity in California in the 1980s.
