A DisasterMovie features an earthquake, volcano or some other ground-based phenomenon and does it in a relatively entertaining way. Then the FridgeLogic hits that Geology Does Not Work That Way. It doesn't always spoil the film -- sometimes only an expert would know, or sometimes the viewer doesn't catch on until after the movie, but it sure can get on your nerves.

Artistic License Geology is the catch-all term for where a work shows a geological phenomenon, but does so inaccurately.

For earthquakes, fissures do not chase B actors or swallow entire cities whole without a trace. For volcanoes, outrunning the lava flow in RealLife is as easy as picking up your pace to a brisk walk, and you're more likely to be overcome by fumes than caught by the molten rock -- so maybe you ''should'' run. Speaking of which, it's not the lava that kills you, it's the [[ConvectionSchmonvection tremendous and far-reaching heat]] that would overwhelm you. It's molten rock, and if you're that close, you'll spontaneously combust from the heat before the lava catches you.

In addition to quakes and volcanoes, this trope also covers any abuses of the field of geology including getting rocks, minerals, or whole processes wrong.

[[folder: Anime and Manga]]

* In ''Anime/CodeGeass'', when the F.L.E.I.J.A. bomb is deployed it leaves a [[http://codegeass.wikia.com/wiki/F.L.E.I.J.A./ 1300 meter-deep crater]], but the now exposed terrain is uniform and absent of geological layers. It's possible the weapon burns the exposed earth to a uniform appearance, but that appearance is regular soil brown.


[[folder: Comic Books]]

* Many old Creator/MarvelComics stories had characters visiting Subterrania, a land located at "the center of the Earth." The place was later {{Ret Con}}ned as being a cave system not far from the surface.
* The MagicalLand realm of Skartaris in Creator/DCComics' ''ComicBook/TheWarlord'' is located in the center of a HollowWorld Earth as a tribute to the ''Literature/{{Pellucidar}}'' novels of Creator/EdgarRiceBurroughs.
* One dinosaur comic has paleontologists find "the most complete T. Rex skeleton ever", and carbon-date it to make sure it's genuine. Carbon dating is not used on objects older than 30,000 years (by then, any radioactive carbon-14 in the sample has decayed to unusable levels); it might serve to rule out the possibility that it's a modern-era replica but there's probably easier ways of doing that.


[[folder: Film]]

* ''Film/{{Volcano}}'' has the titular feature pop out of the La Brea Tar Pits in Los Angeles- while the area is tectonically active, the faults are not the type that generate volcanoes, being too far below the surface. The LA Basin as a whole has no volcanic features newer than a couple dozen million years.
* ''Film/DantesPeak'', a [[DuelingMovies dueling movie]] with ''Film/{{Volcano}}'', made more of an attempt to be accurate but still pick and chose things to be dramatic (the USGS has a detailed response somewhere.) For example, there is fluid lava during what is otherwise a large explosive eruption, (the two are exclusive), and there's a pyroclastic cloud chase scene where the vehicle has way too little lead time.
* The volcano part of ''Film/{{Congo}}'' had many geologic sins (diamonds in basalt, etc), but often gets faulted for one part that was actually accurate; the speed of the flow. The Congo is the only place in the world where lava actually can move at freeway speeds due to its consistency (think mud bath, only it would melt your face instead of cleansing your pores).
* ''Film/{{Earthquake}}'' is guilty of this for the magnitude. The quake in the film hits a 9.9 on the Richter scale, and is judged entirely by the massive damage the quake leaves behind in Los Angeles (something that should actually be left to the Mercalli intensity scale). In real life, not only has a 9.9 earthquake never happened in recorded history (the strongest earthquake ever was 9.4-9.6 in Chile, in May 1960), but it's scientifically impossible for one to strike since rock lacks the capability to build up that much pressure before it gives to the quake. Scientific consensus on the San Andreas Fault (the source for most of L.A.'s quakes) finds that the fault is [[http://earthquake.usgs.gov/learn/topics/megaqk_facts_fantasy.php very limited in trying to cause a mega-thrust quake]] (quakes at or greater than 8.0 on the Richter scale).
-->''The magnitude of an earthquake is related to the area of the fault on which it occurs - the larger the fault area, the larger the earthquake. The San Andreas Fault is 800 miles long and only about 10-12 miles deep, so that earthquakes larger than magnitude 8.3 are extremely unlikely.''
* ''Film/{{Waterworld}}'' explicitly attributes the Earth's submerged status to global warming, but all the ice in the world melting would produce only a 216ft (66m) rise in sea level, which would suck for low-lying coastal areas, but is not nearly enough to create the ocean planet depicted.
* ''Crack In The World'' from 1965 suffered from a fast case of ScienceMarchesOn. It was in line with accepted theory at the time the film was made, but the time the film was released geology was undergoing a revolution, and the Plate Tectonics theory was finally gaining acceptance, making much of the geology in the movie nonsensical as the title went from being regarded as possible apocalypse to normal state of the Earth. (Geothermal energy was also a very new idea at the time of the film; now countries like Iceland use it routinely, and don't need atomic bombs to access it!)
* In ''Film/{{Outlander}}'', the protagonists trek through lava-filled tunnels in Norway. The Fennoscandian Shield which makes up Norway's land mass is one of the most tectonically stable areas in the world, and has had no volcanic activity for hundreds of millions of years.
* ''Film/TwoThousandTwelve'' pretty clearly throws any accuracy out in favor of RuleOfCool. It would be easier to list the couple correct pits than the many, many wrong parts.
* In ''Film/GameraVsZigra'', the main villain causes multiple earthquakes. The strongest earthquake in the film does a lot of damage, but most buildings are still left standing. This earthquake is said to have a magnitude of 18 on the Richter scale -- More than ''100,000,000'' times more powerful than the strongest earthquake ever recorded. Such a quake is impossible (The scale itself goes only to 10, because anything above that is implausible) and would rend the earth apart.
* ''Film/TheCore'' was written entirely with RuleOfCool in mind. Some of the events made it clear that the writers had checked geology books while writing, but the plot makes it easily clear they were completely willing to throw it out when it got in the way of making a ship that went through the mantle like a submarine or death ray gaps in the magnetic field.
* In Peter Jackson's ReturnOfTheKing, the destruction of the ring is accompanied by Mount Doom erupting... but it has both lava flows and pyroclastic explosions, while in reality volcanoes can only have one or the other. Of course, the eruption is the death throe of a demonic sorcerer, so most likely AWizardDidIt.


[[folder: Literature]]

* Creator/JulesVerne's ''Literature/JourneyToTheCenterOfTheEarth'' (and its many movie remakes and retellings) is a prime example of this. Verne was more concerned with following the RuleOfCool in this book than the current scientific understanding of the interior of the Earth. His narrator in this story, Axel, is a geology student, and is continually [[LampshadeHanging lampshading]] how utterly impossible what they are doing should be, with his explanations being consistent with 19th century geologic theories, and they still stand up pretty well.
* There is a ''Literature/TheHardyBoys'' novel wherein the boys experienced a powerful earthquake that lasted about a minute and threw them off their feet. We later find out that the quake measured "between 3 and 4 on the Richter scale." As any Californian could tell you, you might not even ''notice'' a tremor of that magnitude, especially if your attention was focused on something else at the time. And if you did notice it, your first reaction would not be "Yikes, earthquake!" but "That must be a pretty big truck."
* The ''Literature/{{Flood}}'' series has the Earth flooded by water from the mantle, loosely based on research that has shown that the deep crust is downright saturated with water and hydrogen gas, trapped by layers of impermeable rock above it, according to samples from the [[http://en.wikipedia.org/wiki/Kola_Superdeep_Borehole#Research Kola Superdeep Borehole]]. That there's enough of it to flood the planet with 50-60 km of water, or indeed have any way of escaping to the surface en masse, is certainly less than likely -- the research that Baxter cites at the end refers to a mass of water-bearing ''rock'', in which the actual water is a small percentage of the rock and trapped within the crystal structure of the minerals making it up, as well as in minute pore spaces (although amusingly enough, the research paper author said he'd been getting letters and e-mails from people asking him if it was the water from Noah's Flood). There's no way for it to physically come up to the surface in a huge flood.
* Very common in Franchise/CthulhuMythos stories. While some elements such as [[http://www.telegraph.co.uk/news/worldnews/asia/japan/10464231/Volcano-raises-new-island-far-south-of-Japan.html islands rising from the sea floor]] might be justified under RuleOfCool, ScienceMarchesOn, and/or [[AWizardDidIt An]] EldritchAbomination [[AWizardDidIt Did It]].
* In ''Wither'', the first book of the Chemical Garden Trilogy by Lauren De Stefano, North America is the only land mass remaining because the government destroyed the other continents with some super weapon, so a only a few small, uninhabitable islands remain. The destruction of all the other continents has no ill effect on North America or the environment in general.
* Lampshaded in the ''IronDruidChronicles'' the druid Atticus Sullivan made a deal with the Native god Coyote to 'move some earth'. He finds out that this involves him magically placing a gold vein in a specific location where Coyote wants a mine to be built. He protests that while he can do this, it would be geologically impossible for gold to be found in that location. It would be so unprecedented that geologists all over the world will question the basic principles of the science. Coyote does not care.
* Creator/ArthurConanDoyle's story ''Literature/TheTerrorOfBlueJohnGap'' ([[http://en.wikipedia.org/wiki/The_Terror_of_Blue_John_Gap described here]]) has the semi-precious stone [[http://en.wikipedia.org/wiki/Derbyshire_Blue_John Blue John]] occurring in the wrong part of Derbyshire.
* Doyle's Literature/SherlockHolmes story "The Adventure of the Blue Carbuncle" misuses the term "carbuncle", as it's actually a term for ''red'' garnets cut in a particular style. It is not clear whether this is a mistake by the author or if the stone in question has acquired a misleading nickname in-universe.


[[folder: Live-Action TV]]

* The made-for-Sci-Fi-Channel movie ''Magma: Volcanic Disaster''. Volcanoes without precursory activity? Check. Fast moving lava? Check. Lava in places not normally found (such as above the actors head's when inside a tunnel)? Check. Among other things.
* In the miniseries ''Series/TenPointFive'', a volcano erupts without any hint of activity and a ground fissure chases a train, and the very title is not possible,[[note]]At least not through normal geological processes. A sufficiently large impact event could produce a 10.5 or higher magnitude earthquake, but then it would also do a lot of other really nasty things to the planet.[[/note]] among many other errors. Immediately following the original airing of ''10.5'' a local news program of the same network showed a bunch of real-life geologists watching ''10.5'' and laughing their heads off.
* In one Series/SteptoeAndSon episode, the pair try to hawk a zircon to a half-blind fence as a diamond, figuring that he won't be able to see that it's fake. However, he "tests" it by smashing it with a hammer. This test wouldn't work in reality; a diamond would break at least as easily as a zircon.


[[folder: Music]]

* Daler Mehndi's ''Tunak Tunak Tun'' music video shows major depressions in the Indian Ocean when the Earth is viewed from space.
* In "Visions of Paradise", Music/TheMoodyBlues refer to "blue onyx". Onyx, a form of chalcedony, occurs in many colors, but notably, ''not'' blue.


[[folder: Videogames]]

* ''VideoGame/ColossalCave'':
** This game has a volcano in a limestone cave system. While here's nothing preventing a volcanic intrusion from occurring in an area with caves, which might cause magma to enter the cave system, it would not create an actual volcano. Another problem is that because of the presence of the ''hot magma'', the limestone should have recrystallized as marble, or melted to become a calcic igneous rock.
** Unlike most computer games set underground, the trope is averted in the very first version which was a fairly accurate simulation of the real Bedquilt Cave in Kentucky, with a few fantasy elements thrown in. Later versions (including the first complete version, finished by Don Woods) included more fantasy and magic, including the volcano, but the actual cave layout, being described by an experienced caver, is still quite accurate to the real place.
* The mines of the ''VideoGame/HarvestMoon'' games. Even discounting the one set in [[ConvectionSchmonvection a semi-active volcano]], you have mines where you can find gold, silver and copper, along with emeralds, rubies, and diamonds ''on the same level''. Older games at least tried to pay lip service to reality by having the precious gems and metals in different mines, but that was abandoned in favor of streamlining.
* Largely averted in ''VideoGame/DwarfFortress'' except for some minor issues with ConvectionSchmonvection and some dwarves being tough enough to drown in the lava before being burned in it.
* Lots of games have "diamond" weapons or armor, assuming that since diamond is hard, it must be very durable. In fact, diamond crystals have perfect cleavage in four directions and are therefore quite brittle: ''scratching'' a diamond is hard, but ''breaking'' it is not. (An exception is ''VideoGame/MassEffect2'', where the ''Normandy'' can be upgraded with armor composed of carbon nanotube sheets interwoven with diamond [[http://en.wikipedia.org/wiki/Chemical_vapor_deposition chemical vapor deposition]], crushed into dense layers which compensate for diamond's brittleness.)
* A number of ores that can be mined in ''VideoGame/TheElderScrollsVSkyrim'' have real-life names, but are actually fantastic metals that bear little resemblance to that which they were named after:
** Corundum is depicted as a greenish ore that can be melted into opaque dark gold ingots. Real Life corundum is a crystalline form of aluminum oxide best known as "sapphire" and "ruby" when it is gem-quality. If you were to melt it, it'd turn into alumina, which is white.
** Ebony is depicted as a rough black ore which can be melted into dull, malleable ingots, which can in turn be crafted into either glassy black armor or dull grey-black weapons. In the lore, it's said to be a super-durable glassy substance with mystical and holy properties. Real life ebony is a type of wood.
** Malachite in real life is a glassy greenish mineral, much closer to its appearance in ''Skyrim'' than the other examples listed here, and is actually an ore of copper. However, actual malachite armor wouldn't work at all well -- malachite is a rock, and not a very strong one at that, and as such is much more brittle than metal and would shatter under even moderate force.
** ''Skyrim'''s moonstone is in a similar situation to the malachite, it is fairly close in appearance to the real-life counterpart (a gemstone), but is noticeably more useful for making practical armor.
** Quicksilver is another name for mercury, which is a liquid at room temperature.
* ''VideoGame/GoldenSun'': The world is simultaneously based on our own (during a different geological era) and yet [[FlatWorld is flat]] with [[WaterfallIntoTheAbyss water constantly falling over the edges]] ([[{{Literature/Discworld}} no word on giant turtles]]). Landmasses are apparently afloat on the oceans, as evidenced by a tidal wave at the beginning of the game that causes Weyard's version of India to slam into Australia in minutes, resulting in... very little damage, actually.


[[folder: Webcomics]]

* InUniverse example in ''WebComic/DarthsAndDroids'' when Jim and Ben [[http://darthsanddroids.net/episodes/0035.html call the GM on this trope]] with regards to Naboo being hollow and water-filled. Later on, the GM has Jim, a geophysics Ph.D. student, [[http://darthsanddroids.net/episodes/0150.html figures out how it could work]] (which requires him to {{retcon}} in that Naboo has a moon).
--> '''GM:''' It was there all along. I swear.


[[folder: Western Animation]]

* In the ''WesternAnimation/TeenageMutantNinjaTurtles1987'' episode "Turtles at the Earth's Core" the Turtles meet dinosaurs from "beneath the Earth's core". Since the core is, by definition, at the center of the spherical Earth and thus at the point where the planet's gravity pulls ''to'', there's no such thing as ''beneath'' the core -- pass the core and you'll simply start digging ''up'' in the mantle on the other side.
* ''WesternAnimation/Ben10'': Iron/steel, or "bicenthium alloy", is stated to be exceptionally rare anywhere except Earth. This despite iron being the sixth most common element in the universe. Apparently they didn't realize why Mars was red, either.
