Most earthquake kits are geared towards like three days.. although I think they recently raised the specs to have enough stuff to last a week or ten days.
Like I said, basic skills! Even being able to do something like make a hot cup of coffee can help hugely in the mental stress - coping arena.
Everyone should go and bookmark it for that coming rainy day...
