Io Predicted Heat Flow Map
Date: 4 Apr 2013
This map shows predicted heat flow at the surface of Jupiter's moon Io from two tidal-heating models. Red indicates areas where more heat is expected; blue where less heat is expected.
Figure A predicts surface heat concentration at the poles if tidal heating occurs primarily within Io's deep mantle.
Figure B shows surface heat concentrations at the equator if heating occurs primarily within Io's shallower asthenosphere.
