One of Cassini's greatest discoveries has been the ice geysers pouring out of Saturn's moon Enceladus. It appears, that this icy moon isn't alone. Two other Saturnian moons are generating great gouts of icy particles too, suggesting that they might be active geologically. ...

To be active geologically requires either a radioactive core or serious tidal displacement of a massive rocky core. Even using 'Jerry' predictions of Saturn system masses - twice those of Newton -, it is difficult to figure geological activity in Tethys. If this outgassing is occurring, the mass-limited constraints upon gravitational effects force the consideration of unexpected electrodynamic effects.

Dione is rather dense for an icy satellite, but Tethys seems to be almost pure ice. The former has been suspected to be an outgasser for a some time, but Tethys? It doesn't even have any young surface features.
