Enceladus is a small icy satellite of Saturn. Its south polar region consists of young, tectonically deformed terrain and has an anomalously high heat flux. This heat flux is probably due to localized tidal dissipation within either the ice shell or the underlying silicate core. The surface deformation is plausibly due to upwelling of low-density material (diapirism) as a result of this tidal heating. Here we show that the current polar location of the hotspot can be explained by reorientation…

Shear heating as the origin of the plumes and heat flux on Enceladus
TLDR
It is shown that the most likely explanation for the heat and vapour production is shear heating by tidally driven lateral (strike-slip) fault motion with displacement of ∼0.5 m over a tidal period, suggesting that the ice shell is decoupled from the silicate interior by a subsurface ocean.

Images of the Uranian moon Miranda show three areas of complex terrain, trapezoidal to ovoid in shape, with no previously known counterpart. These features, called coronae, are characterized by an

Subparallel ridges and troughs in the outer belt of Arden Corona, on the Uranian satellite Miranda, are interpreted as tilt blocks formed by extension and normal faulting. Fault scarps generally face
Cassini Encounters Enceladus: Background and the Discovery of a South Polar Hot Spot
TLDR
Cassini's Composite Infrared Spectrometer (CIRS) detected 3 to 7 gigawatts of thermal emission from the south polar troughs at temperatures up to 145 kelvin or higher, making Enceladus only the third known solid planetary body—after Earth and Io—that is sufficiently geologically active for its internal heat to be detected by remote sensing.
Geodynamics of Icy Satellites
Geodynamics concerns the internal structure, differentiation and convection, and tectonics of worlds. With respect to icy satellites there exists an excellent literature (e.g., Burns, 1986), and for
Cassini Observes the Active South Pole of Enceladus
TLDR
The shape of Enceladus suggests a possible intense heating epoch in the past by capture into a 1:4 secondary spin/orbit resonance.
