Loki the Volcano

There has been lots of talk in Baton Rouge about ice, snow, and cold. Let’s change focus and talk about something hot: volcanoes! The planetarium is about to debut its latest show “Super Volcanoes” which gives audiences a front row seat to some of Earth’s largest volcanic eruptions. The show features extensive live action footage of geothermal features in Yellowstone National Park, as well as a complex simulation of an eruption of the Solar System’s largest active volcano, Loki.

Loki can be found on Jupiter’s moon Io. Named for the Norse God of Mischief (or comic book villain if you prefer), this volcano is considered to be the hottest and most powerful in the Solar System. Loki is officially called Loki Patera which means “Loki Basin”. Loki is not a tall volcano, it has no cone. It is the opposite, a large depression in Io’s surface that is filled with lava. Loki alone puts out more heat than all of Earth’s volcanoes combined!


So why is this? As we rub our hands together to stay warm in this winter weather we’re having here in Baton Rouge, consider the moon Io. Io orbits closest to Jupiter out of the four largest moons. The combination of tidal forces from Jupiter, tidal forces from the other large moons, as well as the shape of Io’s orbit all play a role. The constant tugging on Io is thought to cause friction and internal heat inside the moon. Kind of like when you rub your hands together but a lot more so!


Images of spacecraft have also shown plumes of volcanic material being ejected from Loki that have reached nearly 150 Km above the surface (that’s higher than the International Space Station orbits above Earth!). In “Super Volcanoes” audiences will travel to Loki and witness what this eruption might look like from the surface!

If you haven’t already, check out the trailer for “Super Volcanoes”, opening February 1 at the Irene W. Pennington Planetarium.
