We tend not to think about it, but we do, daily - we tell ourselves that on any given day it could happen, but we don't do much more than superficially contemplate the event, rather than say, the after effects.
It has been over 16 years since we had a large earthquake. It doesn't seem like it yet it does, all at the same time, in an odd way. 1994 - 16 = 1977-78. We surely had several quakes between 1977-78 and 1994, yet we have had none (of any notice).
