DESCRIPTION:Jupiter’s moon Io is the most volcanically active body in th
 e solar system\, and is part of a growing class of discovered ‘lava-worl
 ds’. Volcanism transports vast quantities of heat from Io’s interior t
 o the surface\, a heat transfer mechanism with significant implications fo
 r interior structure. We present a model of coupled magmatism and volcanis
 m applied to Io. Intrusive and extrusive rates control the thickness of Io
 ’s crust\, whilst continual melting and extraction from the interior\, t
 ogether with suppressed convection could have resulted in a strongly layer
 ed mantle. Our results are in agreement with all currently available obser
 vations of Io\, and present hypotheses readily testable by future missions
