The looting appears pointless, since all the stuff will have to be abandoned anyway.
50-60% of homes with some minor damage (shingles/siding)
The long-dead Pat Frank ( Alas, Babylon, and How to Survive the H-Bomb-- and Why? ) was a reporter across the world before breaking into hardcover books, and he noted that looting always follows wars and natural disasters, and always follows a set pattern. Since it's been over 30 years, I can't recall the exact order, but it's something like, liquor and guns first, cigarettes, luxury items & jewelery, then necessities.
