Tidal forces can cause the surface of Jupiter's moon Io to bulge up to 100 meters (330 feet).
On Earth, the biggest difference between low and high tide is 18 meters (60 feet), and this is for water, not a solid surface!
All of that stress makes Io the most volcanically active world in our solar system.
