A key consideration in setting up a survival camp is the location in relationship to potential hazards such as Tidal Bore, Tsunamis, Sloshing, Flash Floods, Earthquakes, Tornadoes, or the drift of Volcanic Ash clouds. Proximity to man-made hazards such as Chemicals or nerve gas near Seattle/Portland or Utah or other chemical weapons stored in US Military Depots, a leftover from the Cold War, or a toxic waste dump could pose dangers. Rupturing Dams are another likely hazard, as well as the local Hydrology, which may alter due to the massive earthquakes. Mud Slides are caused by water logged unstable soil, and will increase in torential downpours. NOAA provides safety steps for severe weather hazards.
