Our biggest threats around here are tornadoes and ice storms. We prepare for them by having food, water, back-up heat sources, and emergency lighting.
We are not as prone to damage from an earthquake on the New Madrid fault line like Randy, and are high enough to not be concerned with flooding. Other concerns like social unrest or an expanded war keep us aware but not as concerned. A small solar array will provide electricity to get us by, and we have several radios with short-wave capability to stay informed. We also have the "means" to protect ourselves in the event of other people preying on those who are prepared.
