In many ways, we're lucky  --  our heat and cold don't get all that extreme, we have a biomass generator sitting idle in PA, we have lots of streams and rivers (if the Big One doesn't happen in August or September), there are plenty of people here who are way more than handy, and a lot of our construction is frame, so rubble will be much easier to clear  -- and less lethal.  Many of our "islands" also can be reached by water, so unless we get the Puerto Rico treatment, it won't be impossible to get supplies  --  and a lot of temporary bridges  --  to us, after the cities around the Sound have been taken care of.  

Some of the things we lack include food-distributor warehouses, reserves of fuel,  food-prep factories that can churn out cooked food in quantity, widely-distributed health-care facilities that are in locations likely to survive a big earthquake, and the population density that would give us priority in rescue efforts.

So we need to be a LOT more prepared than most...
