%X Vulcanism was rst detected on Io in 1978 byVoyager 1. Since then it has been recognisedthat Io is the most volcanically active bodyin the Solar System. Although the initialvolcanic activity observed was in the form ofSO2 geysers and sulphur lakes, the Galileomission has detected temperatures as highas 1800K on the surface, far in excess ofthe temperatures that can be explained bysulphur-driven activity. Galileo observa-tions suggest that silicate vulcanism is theprincipal driver of activity, even though thetemperatures measured are even in excessof those measured in terrestrial silicate vul-canism, but the relationship between silicateand sulphur-driven activity is not well un-derstood. We propose a project to monitorlow-temperature vulcanism on Io systemat-ically, using CanariCam on the GTC. Thisproject will allow a better understanding ofthe mechanisms of sulphur-driven vulcanism,and the relative importance of silicate andsulphur-driven activity.
