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 on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
The names of volcanic features on Io use a combination of a name derived from mythological figures from around the world related to the Sun, fire, volcanoes, thunder, or smithing, places from the Greek mythological story of Io, Dante's Inferno, or from the name of a nearby feature on Io's surface and an approved descriptive term. The ...
With over 400 active volcanoes, Io is the most geologically active object in the Solar System. [12] [13] [14] This extreme geologic activity is the result of tidal heating from friction generated within Io's interior as it is pulled between Jupiter and the other Galilean moons—Europa, Ganymede and Callisto.
Pele is an active volcano on the surface of Jupiter's moon Io. It is located on Io's trailing hemisphere at 18°42′S 255°18′W / 18.7°S 255.3°W / -18.7; -255 A large, 300-kilometer (190 mi) tall volcanic plume has been observed at Pele by various spacecraft starting with Voyager 1 in 1979, though it has not been persistent.

Animation of eruption from Tvashtar Paterae (Io), taken from imagery from the New Horizons probe in 2007 Lava flow at Tvashtar Paterae. Io, a moon of the planet Jupiter, is the most volcanically active body in the Solar System. [1] Its volcanoes are believed to eject sulfur and sulfur dioxide, as well as basaltic and ultramafic silicate lavas. [2]
Galileo image of Tupan Patera taken in October 2001. Tupan Patera is an active volcano on Jupiter's moon Io.It is located on Io's anti-Jupiter hemisphere at Tupan consists of a volcanic crater, known as a patera, 79 kilometers across and 900 meters deep. [2]
Elsewhere, the active volcano of Kilauea in Hawaii had been erupting almost constantly from its eastern rift zone since 1983. Then in April 2018, its 35-year-long eruption ended.
Galileo image of Thor taken in October 2001 [1]. Thor is an active volcano on Jupiter's moon Io.It is located on Io's anti-Jupiter hemisphere at A major eruption with high thermal emission and a large, volcanic plume was observed during a Galileo flyby on August 6, 2001, when the spacecraft flew through the outer portions of the plume allowing for direct sampling.
