What is the most important choice you can make about storing anything to Prep for the next Big Earthquake?
Store Water, a lot of it.
Many agencies urge to save 3 days of water 1 gal per person per day. This is super inadequate but better than nothing. Folks forget to include their pets in Water storage calculations. 1 pet could easily = 1 adult in required water units of water per day.
If you do some simple math, in any severe earthquake for instance - if local water supplies are cutoff, and roads and any local runways at the nearest airport(s) are severely damaged - water trucks will not be delivering emergency water to communities.
C130 tankers will not be flying in water supplies to communities ANY TIME SOON after a major quake.
