A shield volcano has been identified on Io, based on photoclinometrically determined slope values and planimetric presentation. The slope values (typically 10°) and 2.5 km height of the volcano imply that it is composed of a material with the mechanical properties of basaltic rock. The height of the volcano may also indicate a minimum value of ∼40 km for the thickness of the local lithosphere.
