The San Andreas Fault Is Not the Only Fault In
Town

• When many people think of faults in California,
  they think of the San Andreas Fault.
• The fact is that the Pacific Plate Boundary moves
  an average of 45 mm per year but the San Andreas
  Fault moves an average of only 25-35 mm per year.
• That means there has to be other fault movement.

• Everyone knows not to build on top of a fault,
  but do they know that the land in between two
  faults or more can create mountains or bodies of
  water?
• The type of rock, whether sedimentary or bedrock,
  and how close you are to a fault determines how
  vulnerable you are to your environmental hazards.

5
Hazards

• Hills shatter into landslides, buildings topple
  flat, bridges collapse, pipes burst, and ruptures
  are born. Tsunamis rage, grounds sink in
  liquefaction, and earthquakes begin. Toxic
  contamination and fires spread, and dams break
  and flood.
• These environmental hazards can cause damage.
  When you buy a house in California, what should
  you look for?

6
Vulnerability

• When the hazards do happen, some places are
  severely impacted far more than others. That
  means they are more vulnerable.
• Hospitals, skyscrapers, and cities are more
  vulnerable to life-threatening situations than
  soccer fields or rural lands.

7
Risks

• When you take a chance that is based on your
  knowledge of hazards and vulnerability, that is
  called a risk.
• We take risks everyday to preserve our lifestyle,
  especially when it comes to living near active
  faults.

Conclusion

• Risks are based on hazards and vulnerability,
  which these are overlooked by builders who assume
  that the San Andreas fault is the only fault in
  town.
• The more you get to know about the earth you live
  on, the lesser risks you can live around.
