- Io, one of Jupiter's moons, experiences massive eruptions across its surface12. The moon's distorted orbit causes it to flex as it swoops around Jupiter, which causes friction and intense heat in Io's interior1. Io's volcanic activity could be 100 times greater than Earth's, with about 1,350 to 1,500 active volcanoes on Earth and roughly 50 eruptions each year2.Learn more:✕This summary was generated using AI based on multiple online sources.

The stretching causes friction and intense heat in Io’s interior, sparking massive eruptions across its surface.svs.gsfc.nasa.gov/11455Across six flybys, Galileo collected a vast array of infrared and visible images of Io and revealed that the moon experiences volcanic activity that could be 100 times greater than Earth’s. For context, there are about 1,350 to 1,500 active volcanoes on Earth, and a total of roughly 50 eruptions each year.www.planetary.org/worlds/io

The discovery of volcanic plumes at Pele and Loki in 1979 provided conclusive evidence that Io was geologically active. Generally, plumes form when volatiles like sulfur and sulfur dioxide are ejected skyward from Io's volcanoes at speeds reaching 1 kilometre per second (0.62 mi/s), creating umbrella-shaped … See more
Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working … See more
