San Francisco sits directly on the San Andreas Fault and is one of the most earthquake-vulnerable major cities in the world. The 1906 earthquake and fire killed over 3,000 people and destroyed most of the city. The 1989 Loma Prieta earthquake collapsed a section of the Bay Bridge and killed 63 people. Large portions of the city are built on bay fill subject to liquefaction during strong shaking. The city's coastal position also creates tsunami risk from Pacific subduction zone events.
