I know there are a lot of commonsense overall precautions, but I was actually referring to the more immediate response to when a major disaster might be expected to hit your area, for example with hurricane preparedness there is the long-term, 'It'll happen someday" preps such as WaterBOB and a plan for covering the windows, and there's the "It's coming" preps such as actually filling up the WaterBOB and covering your windows, evacuating, and whatnot. I understand that with earthquakes the "It'll happen someday" preps are all that most people do. I'm just wondering if there might be some "Its coming" preps, i.e., if you lived in Seattle and had a pet rat that was exhibiting this very distinct behavioral change for several days on end non-stop, you might consider that now is a good time to spend a week or two backpacking out of state.
