The role of SO2 in volcanism on Io
@article{Smith1979TheRO, title={The role of SO2 in volcanism on Io}, author={B. A. Smith and Eugene Merle Shoemaker and Susan W. Kieffer and Allan F. Cook}, journal={Nature}, year={1979}, volume={280}, pages={738-743} }
Io and Earth are the only planetary bodies known to be volcanically active; the energetics of the eruptive plumes on Io have important structural implications and are closely linked with the presence of sulphur and SO2.

Volcanic features of Io
- GeologyNature
- 1979
Volcanic activity is apparently higher on Io than on any other body in the Solar System. Its volcanic landforms can be compared with features on Earth to indicate the type of volcanism present on Io.
Volcanic resurfacing rates and implications for volatiles on Io
- GeologyNature
- 1979
Resurfacing rates and surface ages on Io are estimated, together with the material ejection and deposition rates of the active volcanic plumes.
Volcanic origin of the eruptive plumes on io.
- Geology, PhysicsScience
- 1981
A quadruple long exposure of Io in eclipse exhibits faint auroral emission from the eruptive plumes, and heat from the interior of Io appears to be the predominant source of energy in the plumes.
Dynamics of volcanic plumes on Io
- PhysicsNature
- 1979
Ballistic and aerodynamic models are proposed to explain the volcanic plumes on Io, with particular reference to Plumes 1 and 3 which seem to have the same origin.
A comparison of volcanic eruption processes on Earth, Moon, Mars, Io and Venus
- GeologyNature

The silicate planets and satellites display a wide range of physical, chemical and atmospheric characteristics which may influence the nature of volcanism, a major geological process common to the…
Pyroclastic sulphur eruption at Poás volcano, Costa Rica
- GeologyNature

The recent Voyager missions to Jupiter have highlighted the role of sulphur in volcanic processes on Io1–7. Although fumarolic sulphur and SO2 gas are almost universal in terrestrial active…
Volcanic Activity on Io During the Galileo Era
- Geology
- 2003
▪ Abstract Galileo's explorations have revealed a remarkable variety of eruptive styles among Io's diverse volcanoes. Activity at hundreds of volcanic centers ranges from dormant through sporadic to…

The stability of an SO2 atmosphere on Io
- PhysicsNature

Measurements of Io's volcanism and the plasma torus suggest that SO2 is a major constituent of its atmosphere.
Volcanic eruption plumes on Io

An umbrella-shaped plume detected above Io confirms that Io is volcanically active. Preliminary analyses of eight such eruptive plumes are presented.

Application of a newly developed theory to volcanological observations of explosive eruptions shows that previous estimates of pre-explosion gas pressures may be overestimated by an order of…
Melting of Io by Tidal Dissipation
- Physics, GeologyScience
- 1979
The dissipation of tidal energy in Jupiter's satellite Io is likely to have melted a major fraction of the mass. Consequences of a largely molten interior may be evident in pictures of Io's surface…

Identification of gaseous SO2 and new upper limits for other gases on Io
- Environmental Science, GeologyNature
- 1979
Gaseous SO2 has been identified on Io. The estimated abundance of 0.2 cm atm is consistent with an atmosphere in equilibrium with solid SO2 at the local surface equilibrium temperature. Preliminary…

Terrain units and their global distribution on Io are summarised. A map of the complex region of Io is also presented.
Erosional scarps on Io
- GeologyNature
- 1979
Irregular or fretted scarps on Io are similar to those found on Earth and Mars. A sapping mechanism involving liquid SO2 is proposed to explain these complexly eroded terrains on Io.
