By Carol S. Prentice, Geologist 


  • What insights are gained from merging original 1906 observations and field notes with today's earthquake science?
  • Data collected during and after the catastropic 1906 earthquake prove to be essential to-
    • determine the fault's slip rate in the Fort Ross area,
    • map the fault through Peninsula housing developments, and
    • provide a better understanding of the 1989 Loma Prieta earthquake
