Infrared wavelength observations of Io by the Galileo spacecraft show that at least 12 different vents are erupting lavas that are probably hotter than the highest temperature basaltic eruptions on Earth today. In at least one case, the eruption near Pillan Patera, two independent instruments on Galileo show that the lava temperature must have exceeded 1700 kelvin and may have reached 2000 kelvin. The most likely explanation is that these lavas are ultramafic (magnesium-rich) silicates, and…

Extreme Volcanism on Jupiter’s Moon Io
Io (Figure 7.1) is the innermost of the four large Galilean satellites of Jupiter discovered by Galileo Galilei in 1610. Io’s mean radius (1821 km) and bulk density (3.53 g cm−3) are comparable to…
Active volcanism: Effusive eruptions
Io 's most remarkabl e characteristic is its active volcanism. Volcanic erupt ion s on Io co nsist of effus ion s of lava as long lava flows, as lava lake s, and as fire fountains , as well as explos…
Volcanic Activity on Io During the Galileo Era
▪ 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…
Volcanism on Io: the view from Galileo
Io, Jupiter’s innermost Galilean satellite, is the most volcanically active body in the solar system. Ashley Gerard Davies reviews the wealth of data returned by NASA's veteran spacecraft Galileo,…
Io’s Volcanos: Latest Results from Galileo and from the Earth
. Three recent close flybys of Io by the Galileo spacecraft, and new observations from the Hubble Space Telescope and ground-based telescopes, have greatly advanced our understanding of Jupiter's…
Active Volcanism on Io
Io, one of Jupiter9s moons, has hundreds of active volcanoes, many of which are erupting high-temperature silicate lavas. In his Perspective, McEwen reviews how data returned by the Galileo…
Io Volcanism Seen by New Horizons: A Major Eruption of the Tvashtar Volcano
TLDR
The Tvashtar volcanic plume's morphology and dynamics support nonballistic models of large Io plumes and also suggest that most visible plume particles condensed within the plume rather than being ejected from the source.
Exotic Lava Flows
On Earth, most lavas have silica contents in the range from 30 to 78 wt%, and they are erupted at temperatures between 800 and 1170°C (see Chapter 2). However, some lavas have compositions and…
Silicate Cooling Model Fits to Galileo NIMS Data of Volcanism on Io
Abstract The Near Infrared Mapping Spectrometer (NIMS) has obtained spectra of volcanoes on the surface of the jovian satellite Io. Fits to data using a silicate cooling model allow us to constrain…
A close-up look at Io from Galileo's near-infrared mapping spectrometer.
Infrared spectral images of Jupiter's volcanic moon Io, acquired during the October and November 1999 and February 2000 flybys of the Galileo spacecraft, were used to study the thermal structure and…

Io: Evidence for Silicate Volcanism in 1986
TLDR
Infrared observations of Io during the 1986 apparition of Jupiter indicate that a large eruptive event occurred on the leading side of Io on 7 August 1986, Universal Time, and constitutes strong evidence for active silicate volcanism on the surface of Io.
Violent silicate volcanism on Io in 1996
We monitored Io's volcanic thermal emission from 1.7 to 4.8 µm in 1995/96. The data reveal a number of brightenings when Io's thermal emission increased several‐fold. We use a model of emission from…
A history of high‐temperature Io volcanism: February 1995 to May 1997
Ground‐based observations of Io's infrared thermal emission between February 1995 and May 1997 show several discrete brightenings for which we can constrain locations, fluxes, and durations. Several…

Thermal models for basaltic volcanism on Io
We present a new model for the thermal emissions from active basaltic eruptions on Io. While our methodology shares many similarities with previous work, it is significantly different in that (1) it…
Volcanic Eruptions on Io: Heat Flow, Resurfacing, and Lava Composition
Abstract We model an infrared outburst on Io as being due to a large, erupting lava flow which increased its area at a rate of 1.5 × 10 5 m 2 sec -1 and cooled from 1225 to 555 K over the 2.583-hr…

Silicate volcanism on Io
Io is currently emitting 1–1.5 W m−2 of tidal energy as a result of its volcanic activity. If the lithosphere is more than 20 km thick, as appears probable from the surface relief, only a fraction of…
