Land, Image of the Day The data listed below are measures of surface fault slip (scaled in mm) as measured by creepmeters. The quake was centered about seven miles southeast of Parkfield, a town of 37 people known as California’s earthquake capital. The first, in 1857, was a The San Andreas Fault is considered a suitable area to study because minor quakes are very frequent, and every 22 years (on average) an earthquake with a magnitude of 6 or more occurs there. Seismologists discovered that the San Andreas Fault near Parkfield in central California consistently produces a magnitude 6.0 earthquake approximately once every 22 years. Although the 2004 Parkfield earthquake occured over a decade later than predicted, its magnitude and behavior fulfilled the prediction. The earthquake in 1935 measured a 7.7. The interval between quakes was 24, 20, 21, 12 and 32 years. Another mitigating factor was the liwell, R.
