Volcanism on Io - Wikipedia
WEBIo, with two plumes erupting from its surface, Galileo image, June 1997. 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]
