LavaAddsAwesome, but it doesn't usually just show up in your backyard. Instead, writers need to take you somewhere a little more exotic to see it, like the inside of a cavern. While this makes sense, as that can lead to magma, sometimes the writers take this far too liberally. As a result, you may find yourself watching an adventure cartoon where, if a locale is sufficiently separated from your normal environment, lava may flow in it.

This is also a common manifestation of EarthquakesCauseFissures; it's often not enough for 'just' a gigantic crack in the ground to form, so why not have magma burst out of it too!

Usually associated with caves and a CityOfAdventure but can show up in other "exotic" locales like an alien nest in deep space, or prehistoric times. This trope specifically applies to Lava or Magma, and is not limited to UsefulNotes/{{New York|State}}, or even caves necessarily -- for instance, it could be in TheMountainsOfIllinois.

!!How did the spelunkers miss these?[[note]][[SurvivorshipBias They fell into the lava and died.]] Duh.[[/note]]

[[folder:Film -- Live-Action]]
* Literally in the movie ''Film/DisasterZoneVolcanoInNewYork''. [[ExactlyWhatItSaysOnTheTin Unsurprisingly]].
* There is a Sy-Fy movie with the name of ''Film/MiamiMagma'', with drilling setting off an ancient super volcano guess where?
* In ''Film/TheTimeMachine1960'', a [[WorldWarIII nuclear explosion]] causes a sudden volcanic eruption in 1966 London, causing the traveller to become trapped inside a cave made of petrified lava for hundreds of thousands of years.
* And ''Film/{{Volcano}}''...set in Los Angeles. While southern California does experience a lot of seismic activity, that's not the same thing as volcanic activity!
* Much of the plot of ''Film/IndianaJonesAndTheTempleOfDoom'' is set within a volcano identified as ''The Bleeding Mountain'' [[AllThereInTheManual in the official guide]]. Thing is, in RealLife, there are no active volcanoes on the Indian mainland, ''period''.

[[folder:Live-Action TV]]
* ''Series/MacGyver1985'': "Good Knight, [=MacGyver=]" features a LiteralCliffhanger where Mac and Merlin end up dangling above a LavaPit in a cave in Scotland, a region not exactly famous for its volcanic activity, at least since the Eocene.

[[folder:Video Games]]
* ''VideoGame/AssassinsCreedValhalla:'' One of the "Tombs of the Fallen" has Eivor exploring a truly massive volcanic cave located in the south of England.
* In ''[[VideoGame/BatmanSunsoft Batman: Return of the Joker]]'' for the UsefulNotes/NintendoEntertainmentSystem, part of stage 3-2 involves sailing across a lava pit on a small piece of land. This stage is supposed to be some underground mine in or near Gotham City.
* The MSX version of ''VideoGame/{{Contra}}'' featured stages late in the game where one had to navigate magma caverns. Given, this is deep within a tropical island with a mountain on it.
* The Demon Ruins and Lost Izalith in ''VideoGame/DarkSouls'' do this. Mind you, it is heavily hinted that all the lava comes from the flame of chaos.
* In an excellent "alien" adaptation of the trope, The third scenario of ''VideoGame/{{Doom}}'' suggests that Hell is located not that far from Mars. Cue red skies and seas of lava.
* In one of the stages of the NES ''VideoGame/DoubleDragon'', you must enter a cave from the woods just outside. Only about 15 feet below you is a LavaPit. In New York.
* ''VideoGame/DukeNukem 3D'' didn't shy away from this trope much. In a level themed after the San Andreas Fault, a massive lava lake can be found just a short distance into a cave. While the area is no doubt without frequent tectonic snaps, its generally not known for its lava.
** There's also the secret level "Fusion Station", a space/alien level situated over (what else?) a lava pit.
* While the world won't generate this way in ''VideoGame/DwarfFortress'', you can "import" magma from way below the surface or the nearest volcano. This is very useful both as a source of infinite free heat and particularly fiendish traps... and for spectacularly destroying your fortress if you're careless.
* Most of the final chapter of ''[[VideoGame/GabrielKnight Gabriel Knight: Sins of the Fathers]]'' is set in a fairly modern-looking underground temple -- "hounfor" -- in UsefulNotes/NewOrleans (stated to be about 200 years old). When you destroy the Big Bad's [[LoadBearingBoss power source]], [[CollapsingLair the temple starts falling apart]], floor cracks and something glows at the bottom of the rifts. The final scene shows one of the city landmarks partially covered with glowing lava seeping from the cracks in the ground. Yes, [[AWizardDidIt voodoo magic was involved]], but this isn't what you'd expect from a game that earlier [[ShownTheirWork went to great lengths to stay factually accurate]].
* The ''VideoGame/GodEater'' games have the Infernal Subway, a map set in a lava-flooded train tunnel.
* ''VideoGame/HorizonForbiddenWest'': The ''Burning Shores'' expansion adds the ruins of Los Angeles, which 1000 years into the future has volcanic vents that are continuously pump out lava similar to the volcanoes in Hawaii (the California coast has even become a subtropical rain forest, making it appear even more Hawaii-like).
* In ''VideoGame/{{Minecraft}}'', due to the randomly-generated nature of the game, it's fully possible to encounter an NPC town with a cavern full of lava just underneath or an open lava lake right next to it.
* In the original FDS version of ''VideoGame/SuperMarioBrosTheLostLevels'', World 1-2 had pits of water (if Mario/Luigi fell into these, he will drown) both at the very beginning and in the Warp Zone to World 4. However, in the SNES remake, the pit of water at the beginning is emptied out, and the pits of water in World 4's warp area are replaced with pits of lava.
* In ''VideoGame/ZeldaIITheAdventureOfLink'', the only liquid Link could encounter in a cave was Lava. There's even a lava cave on a beach, early on.

[[folder:Western Animation]]
* One episode of ''WesternAnimation/TheFairlyOddParents'' had the family end up inside a volcano instead of their destination every time. Although the volcano was pretty close to their destination.
* Featured into several episodes of ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'', particularly with the Technodrome. May have been prevalent in Dimension X as well.
* The climax of ''WesternAnimation/TeenTitans2003'''s second season finale is set about a kilometer under [[NoCommunitiesWereHarmed a very San Francisco-like city]]. [[DiabolusExMachina Apropos of nothing]], Terra's [[DishingOutDirt Earth powers]] ''trigger a volcanic eruption'' that fills the cavern with lava in seconds and is capable of destroying the city. [[spoiler:She suffers a SuperPowerMeltdown [[RedemptionEqualsDeath stopping it]].]]
* Dinobot Island in ''WesternAnimation/TransformersAnimated'' was created by a volcano in the middle of Lake Erie.

[[folder:Real Life]]
* 200 million years ago this was RealLife. When North America tore away from Eurasia and Africa (eventually forming the Atlantic Ocean), lava oozed to the surface in the New York area (well, UsefulNotes/NewJersey to be precise), forming the [[http://en.wikipedia.org/wiki/New_Jersey_Palisades New Jersey Palisades]].
* Though not exactly lava, a fiery inferno does exist just beneath the ground in [[https://en.wikipedia.org/wiki/Centralia,_Pennsylvania Centralia]], UsefulNotes/{{Pennsylvania}}. The town sits right above a massive deposit of coal that was accidentally set on fire and has grown too big to put out. The ground often crumbles into the burning pits below, steam rises out from cracks, and most of the former residents fled to places where they won't get burned alive at any random time.
* A rather large mass of magma was detected beneath New England at one point. It may only be about 50 million years before everyone there is screwed.
* 'Arthur's Seat', the famous mountain in Holyrood Park, Edinburgh, is an extinct volcano that last erupted about 340 million years ago.
