Scientific paper
Thermal history calculations indicate that the total tidal heating energy in Io is almost equal to the advectively transferred heat, implying that the observed heat flow from Io is almost equal to the total tidal heating energy. Models using internal dissipation factors (Q) between about 25 and 50, and in which the magma source of volcanism is at a 100-300 km depth, satisfy the heat flow data and the existence of a thick lithosphere. Models with Q = 25 and an advective region thickness of 300 km show that although the temperature distribution in the central region reflects the difference in the efficiency of convective heat transfer and initial temperature distribution, the temperature distribution in the outer region does not change appreciably.
