Recent data from the Cassini spacecraft revealed geyser-like plumes, intense heat flux, and tectonic features including large fractures that cut across the pole, a ring of ridges (red), and radial rifts (blue) on Enceladus, imaged above. The origin of these tectonic features and the relation among the tectonic features, the heat transport, and the plumes is discussed by using a unified thermo-mechanical model of Enceladus.
