Did a drilling operation in Yellowstone National Park unleash a 150-foot lava geyser in April of 2025, as a social media post claimed? No, that's not true: The "Casper Planet" page on which the story originated lists "Satire Street" as the Planet's address. The site prominently displays a disclaimer that includes this phrase: "Did we say this is satire? Well it is, names/locations are made up."
The April 27, 2025 Facebook post (archived here) on the Casper Planet's page appeared under the title "Yellowstone Drilling Accident Unleashes 150-Foot Lava Geyser". It opened:
Emergency crews and scientists are scrambling this morning after a drilling operation in Yellowstone National Park accidentally struck a vein of magma late yesterday afternoon, unleashing a violent lava geyser that continues to shoot over 150 feet into the air.
According to park officials, the drill rig -- part of an experimental geothermal research project -- punctured a pressurized magma pocket believed to be directly connected to the park's main caldera system.
This is what the post looked like on Facebook at the time of writing:
