East or West-Coast Tsunami or the New Madrid Seismic Zone rips off a level 12 quake. It's all pretty much the same, I'm not in the zone of direct damage/effect.

I'd assess my current supplies, the season and what items are likely to become unavailable for a while. Then I'd try to add what I could in available perishables (Imported spices, fruits, nuts and vegetables.)

Food for thought; What products (not produced in the USA) come in through ports on each coast and which can/should be stored/stockpiled against possible shortages due to disrupted shipping?
