Having lived on big fault lines my entire life (Salt Lake City and Seattle), I have been trained from kindergarten on about what to do in an earthquake.

In the closet of my 7th floor apartment I have 1 small-ish backpack full of a handful of useful things like a crank weather radio and some flashlights (all bought on clearance over the years). I also have an orange home depot bucket full of non-perishable, high-calorie food I got off Amazon. And a few cases of water. It takes up about 15% of my closet. I bet I could make the food/water last for a month if I had to.

So the answer is yes! But not everyone did earthquake drills four times a year during 12 years of public school... I am 33.
