"Even if we say only 20% are prepared that is still 1 person out of 5 who is good to go"

I suspect that those 20% (and I think that's a very high estimate) are people who have made at least some preparation, such as having 5 gallons of extra water in a delivered bottle (practically accidental). I seriously doubt that 20% have gone as far as having even three days of necessities on hand.

I've asked several people here in WA (co-workers) if they've made any preparations, and every single one said 'No'. I asked what their plan was if an earthquake hit that night, and the overall response was, "I guess we'll just sit and wait for someone to bring us water and food". And whine and complain that the delivery wasn't fast enough, the water was flat, and the food wasn't hot pizza and hamburgers, and wondering when the local casino would be open again.
