1. San Andreas Fault
2. Much of the densely built-up waterfront around San Francisco sits on landfill, often
a blend of rubble and sediment dredged up from the bay. In a major earthquake,
landfill is more prone to liquefaction than bedrock: it behaves like a liquid, shaking far
more severely, and is more likely to give way altogether.

4. Hayward Fault
