Abstract
The tectonic features observed on the icy satellites of Jupiter and Saturn are described and evidence that Europa and Enceladus are currently geologically active is provided. Processes that can lead to stresses within icy satellites such as volume changes and convection and shell deformation are discussed. Consideration is also given to the faulting, fracturing, and resurfacing which result from these stresses.
