I live in CA less than 500 yards from the San Andreas Fault. Lost one 80-year old house in the 1989 earthquake (epicenter about 8 miles from my house) but built a new house with the insurance. I am prepared for another bigger earthquake as much as I can be. Food, guns & ammo, gardens, generators, etc. etc.. My question is why the Hell does anybody live in tornado/hurricane country?
I have traveled in the South but I wouldn't live there for that reason.
I would recommend bugging out when you are told to and be willing to kiss everything you leave behind goodbye. Have "Go Bags" packed and ready during the season. I have similar preparations, but in an earthquake generally everything is still where you left it, but the house has fallen down around it. As I understand it hurricanes and tornadoes will spread your stuff all to Hell and gone.
In Japan for example, they are piling up safes and stashes of cash in the police stations because people have hoarded cash in their homes. But now their homes have been spread all over the place and there is no way to re-connect the people with their belongings. (Note here: I am at 200 feet above sea level, no tsunami threat here!).
Go bags should have water (lots of it) and a water purifier. Food, first aid pack, I have a HAM radio license so that radio is included in my pack and it can receive all TV and broadcast radio signals. I can also communicate all over the country with it. I highly recommend getting your HAM (Amateur radio) license and becoming proficient in its use. I still need a solar charger to include in my Go Pack.
