The Tunguska Event

Go To

"Perhaps the earliest widely-held theory for the Tunguska explosion was that the world was about to end. As the minutes passed, this theory was dropped in favour of other, less final theories, until today one is hard-pressed to find anyone who truly believes the world ended on the morning of 30 June 1908..."
Kevin Zahnle, Nature, "Leaving No Stone Unturned"

The Tunguska Event was a massive explosion which took place on 30 June, 1908 (or 17 June, if you're going by the Julian calendar still in use in Russia at the time). Due to the mystery and scientific intrigue surrounding the explosion, the Tunguska Event has become widely depicted in popular culture.

Shortly after 7 a.m., residents of the hills northwest of Lake Baikal in Siberia saw a light in the sky, one described as being "nearly as bright as the sun". This was followed by a flash of light, a sound like artillery fire, and a shockwave strong enough to shatter windows and knock people off their feet. Something had exploded in the forest near the Podkamennaya Tunguska River, later calculated to have released energy equivalent to 10-15 megatons of TNT (though some recent experiments indicate that the blast may have actually been smaller, at "only" 3-5 megatons).

In 1921, Russian mineralogist Leonid Kulik concluded from eyewitness accounts that the explosion was from a meteorite impact. He led an expedition to the Tunguska region, hoping to find and salvage the meteor itself. Instead, they found a 50 kilometer-wide region of scorched and felled trees, with no impact crater to be found. Subsequent investigations have attempted to find explanations for the disappearance of the meteor, which still hasn't been found as of 2022. A small lake (Cheko) was suggested to have originated from the impact note , but analysis of sediment samples from the lakebed has ruled out this theorynote .

Today, most scientists agree that the Tunguska Event was caused by a meteoroid exploding in mid-air rather than directly impacting. While such air-bursts are common at higher altitudes, they are rarely close enough to Earth's surface to cause damage. There's some debate over whether the exploding space rock came from a comet (which would explain lack of a solid meteorite body) or an asteroid.

Other less credible, but more interesting, theories suggest that the event was caused by: a deuterium-rich meteorite causing an all-natural thermonuclear explosion; a chunk of antimatter; a miniature black hole passing through the Earth; an alien spacecraft crashing or discharging some kind of superweapon; psychic experiments or magic rituals gone wrong; or a test run of Nikola Tesla's Death Ray. It has also been noted that recent explosions in Siberia, leaving impressive craters and downed trees, are due to pockets of methane being released from defrosting tundra; global warming is speeding up this process and creating another interesting consequence. It has been speculated the Tunguska Event might have been due to a really big build-up of subterranean methane that found its way out.

On February 15, 2013, a 50 foot, 7000 ton meteor airburst over the Chelyabinsk Oblast, releasing the equivalent of 300 kilotons of TNT and injuring 1,200 people. Thanks to the many Russian motorists who use dashcams (to settle traffic and speeding disputes), the Chelyabinsk Superbolide was no mystery, and coincidentally was the largest explosion from an extraterrestrial source since the Tunguska Event.

As shown by the examples below, the Tunguska Event has become a go-to "mysterious explosion" for any fiction writer who wants to put a sprinkling of real-world history on their work.

  • Atomic Robo ascribes to the "Tesla did it" school of thought, naturally - specifically, he used Wardenclyffe Tower to "pinch" reality in order to stop an Eldritch Abomination from manifesting. It only slowed it down.
  • The Darkness V1 #12. The Tunguska incident is caused by a battle between the Angelus and the Darkness.
  • In DC Comics it was the origin of Fireball of the Young Allies, Mr Meteor of the Shadowpact (1908 version) and Red Star of the Teen Titans.
  • The Doctor Who Magazine comic strip "Follow That TARDIS!" has the Doctor being forced at gunpoint to grab a a Leeroy Jenkins and his Closer to Earth bookworm of a brother, since the former wants revenge on the Meddling Monk for damaging his car and not paying him. When they end up in Tunguska, the hothead decides to clear some space, but instead of a grenade, he throws a mini-nuke. The three barely escape, while the Monk's TARDIS ends up damaged.
  • The big Point of Divergence in East of West happens when, through unknown circumstances, the meteor that caused the Tunguska Event in real life lands in America instead, helping end a dragged-out American Civil War. A character even lampshades that it feels like the meteor was supposed to hit someplace else.
  • In Hellboy: "Dr Carp's Experiment", it's mentioned in passing that The Heliopic Brotherhood of Ra, an occult society, was believed to be responsible for the explosion.
  • Marvel:
    • The Ultimate Marvel Ultimate Galactus Trilogy miniseries revealed in the first mini (Ultimate Nightmare) that the Tunguska Incident was caused by the Vision crash-landing to Earth. He (she?) was quickly taken into Russian custody and dissected so its Organic Technology could be used to kickstart a Super-Soldier project, which means no one learned about Gah Lak Tus until about a year before he was supposed to eat Earth. In this universe the Tunguska explosion was said to have happened in 1904 instead of 1908, and Word of God is that the date was moved to make it a century before the release date of the comic in 2004. Warren Ellis, as a rule, does his research.
    • In the main 616 continuity, as part of the Original Sin crossover, Mighty Avengers vol. 2 #12 reveals the Tunguska Event was part of an ancient cabal of powerful immortal rulers using a magic ceremony to create a powerful animal/human creature (a character called 'The Bear', introduced in an earlier "flashback" Iron Man).
    • This contradicts other throwaway references to the cause of the event, like Kang redirecting a direct blast from Black Bolt there, or Doom, Iron Man and Johnny Storm having a fight with him on his time machine. If it's not an allohistorical reference, chances are that huge explosions mixed with time travelers will be the cause. The marvel wiki has a short list of explanations.
  • In Paperinik New Adventures the Tunguska Event is caused by a meteorite made by Unobtainium. The Russian army fights the Evronians over it, but it had already been taken away by locals.
  • A Pink Panther comic book claims it was produced by a time-travel hole which happened to open right in the middle of a nuclear rocket launch in the far future.
  • The short-lived "Shadowline" imprint also had the explosion as a result of a super-powered battle.


    Films — Live-Action 
  • Ghostbusters (1984):
    Dr Ray Stantz: You have been a participant in the biggest interdimensional cross rip since the Tunguska blast of 1909!
    • Ghostbusters: Afterlife elaborates on what the event was in this universe: it was a previous attempt by Gozer to manifest in our dimension.
  • In the extended cut of Hellboy (2004), the event was caused by a 20-ton rock, sent to Earth by the Ogdru Jahad. This rock is vital for opening the portal to the Void.
  • K-20: Legend of the Mask follows on from the idea that Nikola Tesla caused the event during his experiments to broadcast electricity. A Japanese oil magnate was one of the surveyors of the Tunguska site in the Alternate History and he invested in Tesla's project. By the start of the movie there are devices resembling the Wardenclyffe Tower that can accurately transmit electricity to power devices or send lighting-like blasts.
  • According to the Expanded Universe of the Transformers movies, the event was caused by Shockwave's crash-landing on Earth.
  • In the backstory to Tomorrowland, presented in the book Before Tomorrowland, the Tunguska Event was an early test conducted by Nikola Tesla and the Plus Ultra organization to open a rift into an alternate dimension via the atomic bomb. The devastating power of the Tunguska bomb led to the organization looking to alternate technologies. The Manhattan Project as it turns out was an effort to tone down Plus Ultra's original designs into weapons that wouldn't blow big holes in the fabric of reality.

  • There is a short story that goes for two-in-one: the Tunguska Event is caused by the explosion of an alien starship... which was caused by said ship getting hit by a meteorite. For bonus points, Rasputin is involved.
  • In Thomas Pynchon's Against the Day, the event is implied to be connected to Tesla's experiments and/or something invading from Another Dimension and/or a monster unleashed from Beneath the Earth; it's all a bit confusing.
  • In Alice, Girl from the Future, it is stated that the first attempt in time travel involved a kitten who became the Tunguska Event. A later novel, though, has two researchers traveling to see it and finding it a natural phenomenon.
  • In Donald R. Benson's novel And Having Writ the Tunguska event was caused by an alien spaceship crashing. The novel takes place in an alternate timeline where the crew manage to land safely and then spend the next few decades changing history as a side-effect of encouraging the creation of technology that can repair their ship.
  • Known Space: The theory that a quantum black hole was the cause of the event is near-proven in "The Borderland of Sol" after such were found by extrapolating possible orbits from the time and location of the event.
  • Spider Robinson's Callahan's Crosstime Saloon proposed that Tesla's Death Ray caused the event.
  • In Kage Baker's The Company Novels, a defective Immortal claims responsibility for the event, saying that he found that using time travel in a manner other than the series' standard Stable Time Loop method will punch holes in the fabric of reality. He also claims to have wiped out the dinosaurs. It isn't clear if this is the truth, though; he might've been lying, or just completely insane.
  • In the Past Doctor Adventures novel Wages of Sin, the Third Doctor takes his companions Liz and Jo back in time to watch the Tunguska event; they become entangled in contemporary Russian politics, but there's nothing weird about the event itself, which is just a meteoroid — as far as they know. In the Doctor Who New Adventures novel Birthright, featuring the Seventh Doctor, the event turns out to have been caused by a TARDIS exploding.
  • The Dresden Files: Ebenezar McCoy takes credit for this in one book. He probably used an actual asteroid, too: doing so is within his capacity.note 
    • A later book reveals that he was killing a dragon with it.
  • In David Brin's Earth, the event was a very small black hole falling into the earth. Which may or may not have been artificially created by aliens to destroy the world before humanity could become a threat. The black hole is more of a MacGuffin, in that it's never resolved where it came from.
  • In the Superman/Batman novel Enemies and Allies, Lex Luthor's Russian allies have a large kryptonite-bearing meteorite implied to be the Tunguska rock. The radiation has horribly deformed the trees and wildlife around the area, and does the same to humans.
  • In The Grimnoir Chronicles by Larry Correia, set in the early 1930s, a Tesla superweapon caused the Tunguska Event. Preventing the weapon from being used again is central to the plot of Hard Magic, the first book in the series.
  • In Jacek Dukaj's science-fiction/alternative history novel Ice (polish: "Lód"), the Tunguska Event caused dramatic changes in the laws of physics.
  • In Julian May's Intervention, the crash landing alien spaceship version is used. When real aliens visit the site on the centennial of the event, it is widely believed to be a hoax.
  • In the Joe Ledger series novel Extinction Machine, the Tunguska Event was caused by an alien spacecraft crash landing. The resulting debris is highly sought after by certain groups.
  • Alexander Kazantsev published a sci-fi story in 1946 where the explosion was a nuclear-powered Martian spacecraft blowing up. This was likely the source of the Real Life theory that aliens were involved in the explosion. In fact, some entirely fictional elements of the story were later mistaken for things that actually happened around the event, in particular the claim that local residents experienced illness suspiciously similar to acute radiation poisoning.
  • In Secret City the event is never called by name, but explosion was caused by The Lesser Poseidon's Throne, humans' Source of mana, going critical after removal of controlling artefact. This was used to cover tracks of experimental world-hopping ritual from the Great Houses. Throne was presumed to be destroyed in the event, but actually it flew around a bit and then crash-landed, embedding itself in some random hill to be found by Soviets later.
  • In Stanisław Lem's The Star Diaries, time-traveling scientists try to straighten the Earth's axial tilt to make the climate more even. However, they screw it up, the machine they use explodes, and a piece of debris causes the Tunguska Event.
    • And in The Astronauts it's an alien spaceship that crashed, carrying some cultural artifacts.
  • In other Polish book, this time adventure Tomek's Secret Expedition by Alfred Szklarski, the Tunguska event saves the skins of the main characters. While they are almost overwhelmed by bandits chasing after them, the event similar to meteorite impact happens nearby. The heroes are just as awestruck as their pursuers, but manage to shake out of the stupor fast enough to successfully run away, while their pursuers flee in panic. The footnote (something the Tomek series is famous for) explains what Tunguska event was.
  • In Leviathan, Nikola Tesla caused the explosion by using his Death Ray, Goliath. He wishes to use this weapon to stop the ongoing war. Subverted in that it doesn't work. The explosion at Tunguska was actually caused by an asteroid like in real life, and Tesla was only testing Goliath at the same time and ended up believing that he caused the explosion.
  • Miss Peregrine's Home for Peculiar Children has the explosion as the result of a failed immortality ritual which created the Hollowgast, a group that serves as the main antagonists of the series.
  • The Strugatsky Brothers in their Monday Begins on Saturday had one character put forth a theory that the event was caused by the crash-landing of an alien spacecraft that moved backwards in time (compared to our own). To simplify it, from our perspective, the event was caused by the spacecraft taking off, so there was nothing there afterward. Instead, the humans had to check what was located on that spot before the event (i.e. in the alien's future).
  • In The Mystery of Urulgan by Kir Bulychev, Professor Mueller alludes to the Tunguska Event when he is talking with Veronica about meteors.
  • William Barton and Michael Capobianco wrote the 1995 Sherlock Holmes short story "The Adventure of the Russian Grave" in which Professor Moriarty's only canonical mathematical paper, The Dynamics Of An Asteroid, is a Batman Gambit designed to engage Holmes' love of mysteries. It is a trap intended to bring him and Watson to Tunguska on that day at that time. When Holmes realizes this, he and Watson run for their lives, barely making it out alive.
  • In the Star Trek novel Prime Directive, the Tunguska explosion is caused by a meteor impact, but the meteor's trajectory is altered by a Vulcan exploration ship (which is observing the Earth) to prevent it from striking Western Europe and wiping out most of human civilization.
  • Also occurs in the novels Titan, Wizard and Demon, where it was an experiment by the habitat to see if it could hit earth with a rock should it need to destroy us.

  • Sulu mentions the Tunguska Event in the Star Trek: The Original Series episode "That Which Survives" as a comparison to a similar event that befalls the crew. Kirk responds, "If I wanted a Russian history lesson, I would have brought Mr. Chekov."
  • According to The Tick (2016), the Tunguska event was an alien object exploding just above Earth's surface, which created all the superheroes, including the first one, Superion, who emerged from the explosion's center.
  • The Cold Opening in Ultraman Orb was later revealed in Ep. 16 to be Orb causing an equivalent event in "Rusalka", from a runaway explosion caused by the Superior Caliber and Maga-Zetton's defeat.
  • The "Tunguska" episode of The X-Files takes place in the region and it was implied (if not outright stated) to be a meteor strike, the meteor in question containing some of the Black Oil, which was used by the Russian counterpart to the Syndicate.

  • In the music video for Metallica's "All Nightmare Long", the Tunguska Event is the source of alien spores that reanimate the dead, allowing the USSR to conquer America via a mini-Zombie Apocalypse.

    Tabletop Games 
  • The Call of Cthulhu main rules hint that the event may have been caused by someone summoning Azathoth to the area.
    • The adventure The Spawn of Azathoth specifies: It was caused by a Seed of Azathoth entering the Earth's atmosphere. The Seed was thrown off by the Spawn of Azathoth (AKA Nemesis) circling the Solar System outside the orbit of Pluto.
    • The devastation caused by the Karotechia from Delta Green trying to summon Azathoth at Naudabaum castle is likened to Tunguska, suggesting the two events have similar causes.
    • Eldritch Horror has its own version of the Seed of Azathoth adventure. It's also one of the wilderness sites for expeditions.
  • In the 5th edition Champions supplement "The Mystic World", we learn that a cabal of evil sorcerors/ritual magicians teamed up to drop the magical equivalent of a tactical nuke onto Earth's Archmage. This involved opening a portal to Hell into his home while he was working with an artifact that used Heavenly fire. He lived in the Tunguska region.
  • In Ex Tempore'', it was caused by an experiment by the Strigae.
  • In "Freedom City" universe of Mutants & Masterminds, this event could be a transdimensional tear that allowed the Centurion to cross into the FC universe from his own.
  • In the GURPS worldbook Black Ops, the event was caused by the spaceship of The Greys crashing.
  • In Necessary Evil for Savage Worlds the event is caused by a Protean speceship.
  • It's referenced in two different New World of Darkness books, with two (possibly) different causes:
    • A sidebar in one of the books for Promethean: The Created describes a Promethean obsessed with studying the mysteries of the Divine Fire who attempted to summon an arch-qashmal, a being made up of the very energy that powers the universe. Those who last talked to him saw him in the vicinity of Tunguska in 1908...
    • In the Hunter: The Vigil sourcebook Witch Finders, the Knights of St. George blame the Tunguska Event on one of their number failing to prevent the summoning of a "faceless angel", one of the Eldritch Abomination entities their order worships/wards off. Who's right is, as always, up to the Storyteller. It could easily be both, whether because the Promethean got the wrong number, because the qashmal's presence itself attracted the Angel's attention, or the qashmallim and Faceless Angels are the same creatures...
  • In the Old World of Darkness, The Tunguska Event was the climax of an epic battle between a cabal of Mages and an ancient dragon.
    • Unless you're the Void Engineers, of course, in which case it's the result of the Engineers finding an alien ship somewhere in the Deep Universe and accidentally setting off its main weapon. Cue mini-singularity landing in Russia.
  • One of the old Shadowrun gamebooks contains a shadowtalk reference, apparently from one of the immortal elves, which claims they were actually trying to hit a comet with the asteroid that struck Tunguska. Given the conspiracy-theory-obsessed tone of the conversation, this was probably a joke, if not a deliberate Lampshading of early Shadowrun writers' own tendency to trace far too much of real-world past history to the meddlings of immortal elves and/or dragons.

    Video Games 
  • ANNO: Mutationem: The Tunguska Event is mentioned in the Tunguska Missile's Flavor Text, where the explosion was apparently caused by a salvo of the prototype's missiles, which was then found by some staff from a Tithonus Group lab.
  • This popped up at the end of Assassin's Creed, when you get into the files of the Ancient Conspiracy, it lists a whole bunch of famed artifacts and strange incidents that are connected to, stolen by, or caused by said Conspiracy. The list includes the Tunguska Incident, which was apparently the explosion of a covert laboratory under their control, conducting research on some kind of alien artifact - which, predictably, blew up in their face.
    • The Truth segments in the sequel confirm that it was the destruction of Piece of Eden 34, the Staff with Nikola Tesla's Thought Bomb that caused the event. Expanded on even further in the comic book spinoff, Assassin's Creed: The Fall, where it turns out the protagonist's ancestor was an Assassin sent to retrieve the Staff from a Templar lab. It's not clear who, if anyone, actually wanted it destroyed — if it wasn't simply caught in the explosion because they didn't clear the lab in time.
  • In Azur Lane, a date and a set of coordinates mentioned in a document in Operation Siren alludes to the event. It's not only the origin of the Wisdom Cubes that would later create the Kansen, but it's also implied to be the origin of the Leviathans, the Greater-Scope Villain that made the Sirens resort to using Alternate Timelines to foster the development of the Azur Lane organization.
  • From what players have pieced together using clues left in the levels, the Nazi Zombies problem from the bonus stages of Call of Duty: World at War seem related to a meteor impact in Tunguska.
  • One of Civilization 4's modern-era random events is a mysterious explosion that takes out an arctic forest in your territory in a recreation of the Tunguska Event. It's quite useful, since your scientists are better motivated to explore space and prevent similar meteorite impacts, boosting your production speed of the Apollo Program and laboratories.
  • In Crysis during a spied on conversation between a scientist and a Korean general, pieces of alien artifacts are mentioned to have been found in Tunguska. In the sequel it's confirmed that Jacob Hargreave stole the Nanosuit technology from the aliens (apparently a scouting troop) during or after the Tunguska event. The last piece in the Nanosuit 2's chemical processes is called the Tunguska Iteration.

The event reveals that Koyanskaya is a nature spirit created from the animals killed during the Tunguska Event. As many animals were driven to Tunguska because of hunting from humans, they blamed the humans for the event, and thus Koyanskaya's initial goal is to become a Beast of Humanity to carry their vengeance on all humans.
  • Girls' Frontline's divergence point from the real world timeline begins in the early 20th century when the Russian Empire discovers a buried alien ruin in the Siberian tundra. Their mining efforts to excavate the site inadvertently set off a reactor core in the ruin and causes the Tunguska event. Regardless, some alien relics are recovered and research into them continues even after the Bolshevik Revolution establishes the Soviet Union. While World War II occurs mostly unchanged, it is during the Cold War when additional alien ruins are found near Shanghai (including the body of an actual alien, code-named "GAVIRUL") where the game's setting goes into full-on Alternate History, with the U.S. using alien tech in the Vietnam War and the Soviets doing the same in their invasion of Afghanistan.

  • The Chimera from the Resistance series crashed on Earth in the event, and dominated the isolated Russian Empire by the 1940s.
  • In American timeline from Original War, they've sneaked their expedition to Siberia and retrieved bunch of artifacts from Tunguska. Among them is a cylindrical object, what will later turn out to be a quasi-Time Machine, labelled EON. Once it is used, in the resulting new timeline, the Soviets send their own expedition to Tunguska as their did historically, to find what they will later label as TAWAR.

  • Schlock Mercenary's UNS battleplates - the biggest, baddest, mobile space battle fortresses in the terrestrial fleet - were ostensibly designed to protect against asteroid impacts. They are named for places on Earth subjected to such impacts. The one that Big Bad General Xinchub uses as a flagship for a while is named Tunguska, nicknamed "Gus" for purposes of interacting with the AI. It blew up good — turns out horribly abusing gravitics to show off in the presence of dark matter aliens that dwarf even your impossibly immense ship and are annoyed by the use of gravitics is a bad idea.
