The Central Valley is ringed by faults – the San Andreas fault, California’s largest, on the west, the Garlock fault to the south, and the faults of the Sierra Nevada to the east. The San Andreas fault will create the biggest earthquakes – as big as magnitude 8 – that will disrupt the whole region. But an earthquake near you can be more damaging to your house than magnitude 8 farther away.
