*'''[[Electromagnetic Pulse]]''' ([[EMP]]) is [[electromagnetic]] [[radiation]] from an explosion (especially a [[nuclear]] explosion) or an intensely fluctuating magnetic field such as a [[solar storm]] / [[solar flare]].  The resulting electric and [[magnetic]] fields may couple with electrical/electronic systems to produce damaging [[current]] and [[voltage]] surges.  A large-yield [[nuclear weapon|nuclear warhead]] detonated at sufficient altitude has the potential to generate an EMP burst that would affect the greater part of the contiguous [[United States]].  A solar storm such as hit the [[Earth]] in 1859 would fry all [[satellite]]s in orbit and wipe out a significant portion of the world's electrical devices and [[electrical grid]]s. Depending on how strong the pulse is, unprotected electronics can be destroyed by the current and voltage surge, especially modern, more intricate and fragile components.

*'''[[Earthquake|Great Quakes]], [[Volcanic eruptions]] and [[Hurricanes]]''' , while incapable of causing a world-wide PAW, can create a localized disaster such as the [[Katrina]] induced [[Third World]] conditions that much of the Southeast United States endured in the months following the [[storm]].  [[Tornado]] and major [[flood]]s can cause similar devastation, but on a much smaller scale.

*'''[[Nuclear war|Nuclear attack|]]''' is perhaps the worst possible [[Man-made disaster|man-made apocalypse]] because it could destroy virtually everything on the surface, causing a worldwide [[radioactive]] desert for some number of years forcing all life underground to survive.
