Jupiter's moon Io is known to host active volcanoes. In February and March 2007, the New Horizons spacecraft obtained a global snapshot of Io's volcanism. A 350-kilometer-high volcanic plume was seen to emanate from the Tvashtar volcano (62°N, 122°W), and its motion was observed. The 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.

Volcanism on Io
Jupiter's moon Io is the most volcanically active body in the solar system. Spacecraft images showed a surface dotted with volcanoes, volcanic plumes rising hundreds of kilometers above the surface,Expand
Io’s active volcanoes during the New Horizons era: Insights from New Horizons imaging
In February 2007, the New Horizons spacecraft flew by the Jupiter system, obtaining images of Io, the most volcanically active body in the Solar System. The Multicolor Visible Imaging Camera (MVIC),Expand
DSMC simulation of Io’s unsteady Tvashtar plume
Jupiter’s moon Io supports its rarefied atmosphere with prolific tidally-driven episodic volcanism. Its largest volcanic plumes erupt violently and exhibit intricate structure, their canopies risingExpand
Spatial distribution of volcanoes on Io: implications for tidal heating and magma ascent
Abstract Extreme volcanism on Io results from tidal heating, but its tidal dissipation mechanisms and magma ascent processes are poorly constrained. Here we analyze the distribution of volcanicExpand
Volcanism on Io: Insights from Global Geologic Mapping
We are preparing a new global geo-logic map of Jupiter s volcanic moon, Io. Here we report the type of data that are now available from our global mapping efforts, and how these data can be used toExpand
Io Volcanic Plumes: Spacecraft Flythrough Hazard Evaluation

The global distribution of active Ionian Volcanoes and implications for tidal heating models
Tidal heating is the major source of heat in the outer Solar System. Because of its strong tidal interaction with Jupiter and the other Galilean Satellites, Io is incredibly volcanically active. WeExpand
The variability of volcanic activity at Zamama, Culann, and Tupan Patera on Io as seen by the Galileo Near Infrared Mapping Spectrometer
Abstract Zamama, Culann, and Tupan Patera are three large, persistent volcanic centers on the jovian moon Io. As part of an ongoing project to quantify contributions from individual volcanic centersExpand

Active Volcanism on Io as Seen by Galileo SSI
Abstract Active volcanism on Io has been monitored during the nominal Galileo satellite tour from mid 1996 through late 1997. The Solid State Imaging (SSI) experiment was able to observe manyExpand
High-temperature silicate volcanism on Jupiter's moon Io.
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 onExpand
Io after Galileo
Io, the volcanically active innermost large moon of Jupiter, was a target of intense study during the recently completed NASA Galileo mission to Jupiter (1989–2003). Galileo's suite of instrumentsExpand

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 fromExpand
