"The surface of Io is constantly reforming as molten rock erupts from its many volcanoes. In the 17 years between the Voyager and Galileo missions, one volcano moved 80km across Io's surface. Io's orbit cuts across Jupiter's powerful magnetic lines of force, turning Io into a giant electricity generator. Io can create currents of 3 million amps. This filters back down to Jupiter, creating lightning storms in the planet's upper atmosphere. As Jupiter rotates, its magnetic field sweeps past Io and strips off about 1,000 kg (1 ton) of Io's material every second."
