Nothing. I have resources at my home, some laid in specifically for earthquakes. Earthquakes occur unexpectedly, with no prior warning. There may not be an option to flee, for that matter. Why leave the known and head for the unknown?
With a more resilient infrastructure, there would be relief eventually, most likely within thirty days. I can hang out for that long with no major problems, although I will review my preparations.
