Drawing of cross sections of floating ice shelf shows lifting and falling effect of tides.

Caption

Ice shelves floating on Earth's Southern Ocean rise and fall with tides, causing rifts, fractures. Icequakes occur most frequently when falling tides pull the rifts apart. Models suggest seismic activity on Enceladus likely correspond to the tides inside the moon. From figure 1 of the new study.
