We moved to Canada 3 years ago, and they really push for us all to be prepared to last for 72 hours with no help or access to food and water. I currently have a gas camping stove, tent, water, canned and dried food to last us at least this time, flash lights and batteries, blankets, emergency radio, first aid kit etc.
Also we have an emergency plan incase we aren't together as a family at the time something happens, and a system set up with family where by if we make no contact with a certain relative in a set amount of time or the school cant contact us by satelite phone they will notify the uk embassy and fly out immediately to get the kids.
We are in a quake zone, and what happened in Japan was our worst nightmare, that is what is expected here. We have no way to predict when it will happen it could be next week or 200 years, thats the problem.

Moving here made me realise how utterly unprepared people are for emergencies in the UK, its an island where we dont get massive earth quakes or tsunamis etc, but if the weather gets bad or in case of civil unrest can it really hurt to have a few bottles of water and extra beans in the cupboard?
So going back to frozen chips, probably not relevant in the case of an earthquake :P
