These images were specially processed to show detail both on the surface of Io and in the faint plume. This volcano is named Prometheus. The eruption is thought to be driven by sulfur dioxide gas that is heated by molten sulfur and driven out of the vent at a velocity of about 1/2 km (0.3 mi) per second. The plume reaches an altitude of about 50 km (30 mi), spreading out over a diameter of about 300 km (190 mi).
