Earthquake faults in california map.
Faults are more likely to rupture (more ready) where tectonic stress has built up over many years without an earthquake. Conversely, faults are less likely to rupture (less ready) when and where a recent earthquake has occurred. We may not know when the most recent earthquake occurred on most faults in California, but we can assume it was ...
