One of the easiest ways to indicate that a major, Earth-changing event has taken place is to show a city half-sunken, with buildings at unsafe and possibly nausea-inducing cants. This is sometimes the result of a GreenAesop about GlobalWarming, but more often it's just used to show that something is ''not right'' in the story's setting.

Given the natural fears that arise in an island nation, this happens to Japan a ''lot''.

May be the result of CaliforniaCollapse. For ancient examples see UnderwaterRuins.


[[folder: Anime and Manga ]]

%%* Tokyo in ''Manga/GhostInTheShell''.
* In ''Manga/YokohamaKaidashiKikou'', due to an environmental shift whose details are largely unrevealed, a great many coastal cities are completely covered by the ocean. At least one chapter revolves around exploring one such city, Yokosuka, whose street lights still come on even though the city is completely submerged.
%%* ''Anime/PonyoOnACliffByTheSea'' (in a strangely lighthearted way)
* The namless ruined city in ''Anime/ElHazardTheMagnificentWorld'' used to showcase the ancient destructive power of the demoness Ifurita.
* ''Anime/AgentAika'' has ''modern'' underwater ruins from when the sea levels rose and flooded coastal cities.
* ''Anime/NeonGenesisEvangelion'' has ''[[RuinsOfTheModernAge modern]]'' underwater ruins from when the sea levels rose and flooded coastal cities.
* ''Anime/BlueSubmarineNo6'' shows the flooded ruins of Tokyo at the beginning of the first episode and has even a underwater submarine battle around them in second one.


[[folder: Comic Books ]]

* For a time, ComicBook/{{Aquaman}} was based in Sub Diego: a portion of San Diego that was submerged in an attempt to convert humans into subaquatic beings. The population consisted of a mix of these altered humans and Atlantian refugees.
* ''Creator/TangentComics'': the city of New Atlantis was founded atop the ruins of Atlanta, Georgia, after the Florida peninsula was destroyed in Earth-9's version of the Cuban Missile Crisis.
* In ''ComicBook/{{Drowntown}}'', future London [[GlobalWarming has a lot more water]] than it used to. It's still fully inhabited, however, and has actually gained population as people seek refuge from places that have it worse off. Among other things, the flooding means that water-based transport is now considerably more common one of the main characters is an aqua-courier, riding through what used to be streets.


[[folder: Film ]]

* ''Film/AIArtificialIntelligence'' had underwater ruins of the submerged parts of New York City.
* Kevin Costner's ''Film/{{Waterworld}}'' had underwater ruins... which turn out to be the city of Denver.
* In ''Film/TheDayAfterTomorrow'', a superstorm strikes New York and floods Manhattan.


[[folder: Literature ]]

* Buenos Aires in ''Literature/ConcienciaYVoluntad'', also with many other major coastal cities.
* The 1987 novel ''Drowning Towers'' (or ''The Sea and the Summer'') by George Turner describes a future in which Melbourne was partially submerged in water. As the tops of sky scrapers are above the water level, they are still inhabited by the cities' poorer classes.
* In ''Literature/DarkLife'', any city that is coastal in our time has become this.
%%* The Teeth in ''Literature/ShipBreaker''.
* In ''Literature/TheLordOfTheIsles'', it seems like you can't turn around without without running into a sunken city or island. They don't always stay sunken, either, what with all the wizards running around.
* In ''Literature/TheKillOrder'', Mark often flashes back to living in a skyscraper, because the city was flooded with scorching water after the solar flares melted the ice caps.
* Creator/HPLovecraft's "Literature/TheColourOutOfSpace" takes place in a region of Massachusetts which is eventually flooded to create a reservoir. Several homesteads and small towns end up submerged, including the [[StarfishAliens Colour]]-infested farm. (Minus the Colour, this is TruthInTelevision, as the Quabbin Reservoir was created in this manner.)


%%[[folder: Tabletop Games ]]

%%* ''TabletopGame/FiftyFathoms''


[[folder: Video Games ]]

* ''Franchise/TheLegendOfZelda'':
** Sunken City (possibly the TropeNamer) in ''[[VideoGame/TheLegendOfZeldaOracleGames The Legend of Zelda: Oracle of Seasons]]'', flooded not by rising seawater (it's quite far from the ocean) but by melting snow from the mountains.
** In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', there are flooded ruins of several presumably Hylian villages found downstream of Zora's Domain in the southeastern reaches of Hyrule. Considering that the Zora's Domain story arc in this game involves the threat of a devastating flood caused by [[HumongousMecha Divine Beast Vah Ruta's]] water-generating powers, there's a possibility that Vah Ruta caused some other minor floods in the century since the Great Calamity, especially since these flooded villages ''don't'' have the remains of [[MechaMooks Guardians]] like most other ruins.
* Most of eastern New York State is at least half underwater in ''VideoGame/SuperheroLeagueOfHoboken''. Global warming is to blame. A good part of the game is figuring out how to get to the flooded parts of the city, then to the open water, to reach new locations.
%%* ''VideoGame/FinalFantasyX'' has more than one.
* The city of Thor in ''VideoGame/TalesOfPhantasia'' sunk 2000 years prior to the events of the game due to a meteor crash. It's still, however, relatively dry and functional thanks to [[CapturedSuperEntity Aska's power]]. The protagonists actually get to rise it back to surface on the trip down there (and get elected as the new president to do this).
* In ''VideoGame/DarkSouls'', the city of New Londo is half submerged in water, and mostly populated by homicidal ghosts. It turns out that the city was flooded by the Three Healers when the Darkwraiths (humans feeding on "Humanity" and becoming twisted by the Dark) began to get out of control and the Abyss began to take shape beneath New Londo: flooding the city sealed both of those up and put a stop to the spread of the Abyss.
** ''VideoGame/DarkSouls2'' has a couple: the realm of Heide is almost completely submerged by the sea, with only a couple of towers still habitable above the water. The Iron Keep is likewise sunken... in ''lava''. The Old Iron King became too greedy, and built his castle too high; the castle (suggested to be pure iron) got really, really heavy and partially sank into the volcano the King had insisted it be built on.
* ''VideoGame/TheCrystalKey'' has the Arkonian capital city of Suralon, which was almost completely submerged when the [[EvilOverlord evil psychic Ozgar]] bombarded it with his gravity-altering satellites. Naturally, the people there evacuated the place while it was sinking.
* In ''[[VideoGame/AnnoDomini Anno]] 2070'', set after a massive global warming event, has city ruins occasionally located on underwater plateaus. They can be harvested for building materials.
* In ''VideoGame/AceCombat04ShatteredSkies'', your enemy's capital city, Farbanti, has a submerged downtown full of scorched, tilted skyscrapers (and during the battle, submarines) due to an asteroid impact.
* Given the amount of damage it's suffered after a genocidal civil war, Rapture of ''VideoGame/BioShock'' fame probably counts, even if it thankfully hasn't flooded yet. In the sequel, as you're a Big Daddy in a self-contained suit, you can go outside and see what it's like from without.


[[folder: Western Animation ]]

* Atlanta in ''WesternAnimation/{{Futurama}}'', PlayedForLaughs of course. "The Lost City of Atlanta!"
* In an episode of ''WesternAnimation/CaptainPlanet'', the characters go forward in time and see New York underwater. And yes, it was a GreenAesop about GlobalWarming.
%%* New York and others in ''WesternAnimation/SamsonAndSally''. ("The city that man built".)
* In ''Disney/AtlantisTheLostEmpire'', the titular kingdom's capital is protected by a massive air bubble but the outskirts are exposed to the ocean and in ruins.
* ''WesternAnimation/NeoYokio'': Parts of Neo Yokio are submerged, mainly 14th Street. The top of two skyscrapers poke out of the harbor of Battery Park.


[[folder: Real Life ]]

* In the UK, entire towns have been submerged over the years for various reasons.
* As with the U.K., Italy has its share of submerged towns. One in particular is situated in a lake that gets drained periodically, allowing the interested to go visit.
** Venice is slowly ''sinking into the ocean'' because it's so heavy that the land underneath (formerly marsh, so that's understandable) can't hold up its weight.
* Many of the most ancient parts of Alexandria, in Egypt, have sunken along with the land under them.
