Io's active volcanoes are driven by tidal forces from Jupiter's gravity, causing intense heating due to constant flexing and stretching of its interior. Europa, on the other hand, has a thicker ice crust that insulates its interior, preventing significant tidal heating and volcanic activity.
Io orbits Jupiter at a distance of 421,700 km (262,000 mi) from the planet's center and 350,000 km (217,000 mi) from its cloudtops. It is the innermost of the Galilean satellites of Jupiter, its orbit lying between those of Thebe and Europa. Including Jupiter's inner satellites, Io is the fifth moon out from Jupiter. It takes 42.5 hours to revolve once (fast enough for its motion to be observed over a single night of observation). Io is in a 2:1 mean-motion orbital resonance with Europa and a 4:1 mean-motion orbital resonance with Ganymede, completing two orbits of Jupiter for every one orbit completed by Europa, and four orbits for every one completed by Ganymede. This resonance helps maintain Io's orbital eccentricity (0.0041), which in turn provides the primary heating source for its geologic activity (see the "Tidal heating" section for a more detailed explanation of the process).[27] Without this forced eccentricity, Io's orbit would circularize through tidal dissipation, leading to a geologically less active world.
Io is the closest moon to JUPITER. With that established, yes Io is extremely active in the volcanic sense.
