What is the average width of fault zones in California?

1/8 mile
1/4 mile
1/2 mile
3/4 mile

The correct answer is: 1/4 mile

The average width of fault zones in California is approximately 1/4 mile. This measurement is based on geological studies that analyze the manner in which faults impact the surrounding area. Fault zones typically exhibit a complex structure and can include fractured rock, sheared materials, and other geological features that extend laterally from the fault itself. A width of 1/4 mile allows for the inclusion of various geological influences that result from seismic activity, representing a significant area where stress is accumulated and potentially released during earthquakes. Understanding this width is crucial not only for geological assessment but also for preparedness, urban planning, and disaster management in regions that are seismically active.
