The rule of ImprobableCover states: explosions in movies can't see you if you sidestep behind a wall or jump behind a table.

Of course, as the Series/{{Mythbusters}} showed, this can be TruthInTelevision often some small amount of cover can blunt the "pressure shockwave" caused by the explosion, although insufficient cover probably won't protect you from flames or flying debris also caused by the explosion, which can still injure or kill you.

Sister trope of ConcealmentEqualsCover. Also see BulletproofHumanShield.

[[folder:AnimeAndManga]]
* ''BarefootGen'', Gen survives the detonation of the nuclear bomb simply because there was a wall between him and it. The people around him were not so lucky. Even more terrifying because it actually happened....

[[folder:Film]]
* In ''Film/DoubleTeam'', the heroes hide behind a coke machine and survive despite roaring walls of flame on either side. Possibly a moment of genre-savvy.
* ''Film/IndependenceDay'': Pretty much every time there's an explosion that the heroes escape, they do so by this trope.
** The most blatant is the tunnel one: Jasmine, her son and the dog hiding in a maintenance room inside the tunnel could be plausible... [[ArtisticLicensePhysics if not for the door that remains open with a wall of fire running through and somehow not entering the room]].
* ''Film/{{Predator}}'' and ''Film/{{Predator 2}}''. In the first film Dutch lives through a small nuclear (?) explosion at close range because he ducked behind some cover. In the second film Lieutenant Harrigan survives the exhaust blast of a Predator ship taking off by doing the same thing.
* In ''Film/HotFuzz'' a massive explosion that takes out a whole building is survived by the people ''inside'' it. They do this by [[spoiler:hiding behind some old sofas.]] This is "[[RuleOfFunny explained]]" in the extras.
* ''Film/DantesPeak'': Harry, Mayor Wando and her kids escapee the eruption of the titular volcano by hiding in a mine.
* ''Film/TheDayAfterTomorrow'': They outrun an oncoming ice storm, and escape it by closing a door.
* In the ''Film/DieHard'', series, this happens multiple times.
** In the first film, [=McClane=] builds a homemade bomb and tosses it down an elevator shaft. When it goes off, a blast of fire shoots upward toward him. He survives by stepping to the side of the door.
* Subverted, in ''{{Tremors}}: Aftershocks'', when Earl tosses a bomb in an attempt to kill a Shrieker, it lands [[spoiler: in the bed of a truck packed with explosives. When the others hide behind a nearby building, Burt shouts at them to "Keep running!". They look at Earl, who replies "Burt knows his bombs". After quite a bit more running, they find a ditch, which, combined with the distance, provides sufficient cover.]]
* In ''Film/IndianaJonesAndTheKingdomOfTheCrystalSkull'', Indy survives a nuke by hiding in a refrigerator.

[[folder:LiveActionTV]]
* In the first season finale of ''Series/TheWalkingDead'' Dale and Andrea survive the explosion of the [=CDC=] by flattening themselves against a pile of sandbags.
* In the ''Series/{{Castle}}'' two-parter "Tick, Tick, Tick..." and "Boom!", Beckett survives her apartment being blown up by diving into her bathtub just as the bomb went off. More justified in this case since her tub is one of those old cast iron jobs.
* ''Series/TokumeiSentaiGoBusters'': Ryuji uses a table in #1 to block a bullet attack from the Monster of the Week. Said monster has an arm that can cut through a ''car'' with no effort.

* True of most "heavy" weapons in ''Franchise/MassEffect'', including rocket launchers, anti-materiel rifles, and grenades: all of them are stopped by the flimsiest of cover. However, in ''Mass Effect 3'', enemies have [[ArtificialBrilliance learned to throw grenades behind your cover]] -- and you can return the favor by grabbing [[{{BFG}} a heavy sniper rifle]] and sniping enemies ''through'' cover.
* Against advanced ''VideoGame/{{Half-Life 2}}'' AI, [[http://www.youtube.com/watch?v=e0WqAmuSXEQ the only thing you can do is hide]].

[[folder:Real Life]]
* Nuclear blasts are strange things, sometimes a person can be vaporized while someone standing right next to them survives simply because of a wall. This is mainly because that the heat flash of a weapon will travel like light, areas in complete shadow are completely shielded, even if quite close to ground zero. Sure the wall itself would easily be obliterated by the following blast wave but the point still stands.
* During 9-11, a few survivors were found inside the debris pile. Most had been trapped in the bottom six floors of the stairwells, which had somehow remained partially intact.
* Real bombs shockwaves are tricky things. Running down a side street won't save you if you are still within the danger area - the shockwave spreads out along any route offering least resistance. However when IRA terrorists bombed Manchester City centre, a traditional red telephone box suffered no damage apart from a cracked pane of glass, despite being well inside the cordon, and more extensive damage being wrought around it.
