The San Francisco Bay Region is Earthquake Country!
  • Large earthquakes have occurred in the region throughout its geologic past.
  • The Great Earthquake of 1906 and the recent Loma Prieta Earthquake of 1989 caused tragic losses in the San Francisco Bay region.
  • The potential losses from a repeat of the Great 1906 Earthquake on the same section of the San Andreas Fault are staggering. Such a worst case event could cause 3,000 to 8,000 deaths and 170 to 225 billion dollars in property losses (Bendimerad, et al., 1995).
  • 90 percent of these losses will occur from strong ground shaking.
