You forgot to show the 1989 Loma Prieta Quake in Santa Cruz County. It registered 6.9, resulting in a lot of damage and loss of life. Experienced it first hand.
1989 earthquake or Loma prieta was a very devastating earthquake . I was only a little kid at the time. and all I could remember was my dad not coming home for days at a time (he was a police officer at the time) but I didn't understand until later how destructive it was .
