Methinks there's no need to stockpile. We're not talking about survivalism, are we? We're talking about being prepared for a disruption after an earthquake or some such thing.I'd like to know how the thousands of Victorians living in 700sq-ft condos are expected to stockpile, for 2 people, 7-10 days worth of food, water, fuel (gas for power generation, propane for cooking and heat)..
If your cupboards and refrigerator are 2/3 full at any given moment then you've already done most of the preparation that you could ever require.
Add a rotation of bottled water (in other words, have some water in the fridge in bottles or jugs and drink/refill as part of your daily routine) and you're set.
Basic medical supplies, flashlight and batteries... everyone should already have these things.
You don't really need fuel. The indignity of eating canned food and dried fruit for a few days after a disaster won't be such a big deal, I guarantee it.
Unless our hypothetical earthquake happens to strike during the coldest few days of the year, odds are you'll be fine in these parts without heat as long as you have a good sweater and some blankets and a place to stay dry if it happens to be raining. If it does happen to be really cold then people would need to stick together and get some fires going. There would be no end of stuff to burn.
Like VHF says, it depends on the disaster. Are we talking about total nuclear war or some Hollywood-style once-in-a-million-years natural disaster that utterly trashes modern civilization and keeps it down for generations? If so, then personal preparation is almost a moot point.
Otherwise, everyone should take the simple measures necessary to hold out for a few days in the absence of outside assistance. It's no big deal, it really isn't. If you're the sort of bozo who shops for groceries every day and has an empty fridge and cupboards most of the time, it wouldn't cost you anything to prepare. You'd just need to buy more stuff at once and then shop less often after that.
Some people will say they don't want to keep a full cupboard, because the earthquake might destroy their house/building and thus put those cans of tuna and bags of dried fruit out of reach. These people are utter morons for reasons that I hope I don't need to explain.
