Jurassic World: Volcano

In Jurassic World: Fallen Kingdom (2018)

the island's dormant volcano begins roaring to life ...

My first thought was, why would InGen build a park on an island that has a volcano, especially since they own a second island (The Lost World: Jurassic Park and Jurassic Park III both take place on Isla Sorna).

This made me wonder if the volcano was a retcon or if it was actually mentioned or shown in the original Jurassic Park (1993), e.g. in establishing shots or a maps of the park.


My Question:

  • Is the volcano on Isla Nublar a retcon or did it exist since the first movie?
  • I'm not knocking the question as to whether it's a retcon or not... but people build on volcanoes all the time... Hawaii, the Canaries, Pompeii.... then just hope they don't go off ;) – disassociated Jun 24 '18 at 17:33
  • @Tetsujin - when it comes to a location for my billion dollar theme park I'd rather not take any risks. Hammond had enough money to buy at least two islands, and Lockwood (James Cromwell's character) seems to even have a third island. – Oliver_C Jun 24 '18 at 17:48
  • There's no indication of a volcano in the original movie...or reference to one. I'd put this down as a retcon. – Paulie_D Jun 24 '18 at 19:01

    @Paulie Except to a geologist or anyone who recognised the filming locations in Hawaii used for some scenes, the rocks in the background are clearly igneous extrusive in nature. – Sarriesfan Jun 24 '18 at 23:09
  • In the book and 1993 film, there are no mentions of active volcanoes. However, externally, Kauai (where it was filmed) has volcanic origins. Not an answer, just a comment. – Mikey May 8 at 13:21

Was Isla Nublar always volcanic, or was it a retcon?

An early draft of the script for the first film contains a line by Hammond describing the island explicitly as an extinct volcano (though this line is missing from the final version of the script):

Isla Nublar. Actually an extinct volcano, though there's still volcanic steam in places... as you can see, ocean currents make it permanently covered in mist.

The above line is a paraphrasing of a quote from the original book, which frequently1 mentions the island's volcanic activity. In fact, the island's name itself derives from this:

Isla Nublar, Hammond explained, was not a true island. Rather, it was a seamount, a volcanic upthrusting of rock from the ocean floor. "It's volcanic origins can be seen all over the island," Hammond said. "There are steam vents in many places, and the ground is often hot underfoot. Because of this, and also because of prevailing currents, Isla Nublar lies in a foggy area."


Why would InGen build a park on an island that has a volcano?

We may assume this is because the creators of the park hypothesized a diverse and volcanic environment would be more 'natural' for the animals, or conducive to the preservation of multiple varied species:

It was during the early Triassic period that Procompsognathus had lived... The air was denser. The land was warmer. There were hundreds of active volcanoes. And it was in this environment that Procompsognathus lived.

... when Grant looked at this landscape, he saw... another, very different world, which had vanished eighty million years ago... At that time, there were thin clouds in the sky overhead, darkened by the smoke of nearby volcanoes. The atmosphere was denser, richer in carbon dioxide.

Costa Rica had a remarkable diversity of biological habitats: seacoasts on both the Atlantic and the Pacific; four separate mountain ranges, including twelve-thousand-foot peaks and active volcanoes; rain forests, cloud forests, temperate zones, swampy marshes, and arid deserts. Such ecological diversity sustained an astonishing diversity of plant and animal life. Costa Rica had three times as many species of birds as all of North America. More than a thousand species of orchids. More than five thousand species of insects.

Along the side of the road, clouds of volcanic steam misted rainbows in the bright quartz lights... Land Cruisers moving through fields of steam... The southern end of the island had more volcanic activity than the north.

He smelled the sulfur fumes of the volcanic steam... Already he could smell the sulfur. And up ahead he saw the rising steam of the volcanic fields.
The ground was hot, Gennaro thought, as he walked forward. It was actually hot. And here and there mud bubbled and spat up from the ground. And the reeking, sulfurous steam hissed in great shoulder-high plumes. He felt as if he were walking through hell... They all walked forward, among the bubbling steam vents.

"The raptors are localized in the southern area, down where the volcanic steam fields are. Maybe they like the warmth."... It looked more and more as if Ellie had been correct: the nest was in the southern volcanic fields.

  • I read the novel some 25 years ago (before the movie came out), so that's a detail I didn't remember at all. But aside from "steam vents", does the novel mention a volcano on the island and whether it was considered "active", "dormant" or "extinct"? – Oliver_C Jun 25 '18 at 10:14
  • The added info about the different ecosystem is a very good point, but at the same time you wouldn't want your theme park visitors to have breathing problems. – Oliver_C Jun 25 '18 at 10:27
  • I'll accept this answer based on the link to Crichton's first draft script mentioning that the volcano was considered extinct. - "The southern end of the island had more volcanic activity than the north" Strangely Jurassic World decided to put the volcano on the north of the Island. – Oliver_C Jun 25 '18 at 11:05

    Essentially all Atlantic and Pacific islands are volcanic in origin. – Stop Harming Monica Jun 25 '18 at 12:28
