The most powerful volcanic eruption observed on Io was an "outburst" eruption at Surt, observed by Earth-based astronomers on February 22, 2001. [ 51 ] Explosion-dominated eruptions occur when a body of magma (called a dike ) from deep within Io's partially molten mantle reaches the surface at a fissure.
Infrared image showing night-time thermal emission from the lava lake Pele. Galileo arrived at the Jupiter system in 1995 and, from 1996 to 2001, regularly monitored volcanic activity on Io through observations of Io's thermal emission at near-infrared wavelengths, imaging Io while it was in the Jupiter's shadow in order to look for thermal hotspots at visible and near-infrared wavelengths ...
Voyager 1 observation of Loki Patera and nearby lava flows and volcanic pits. Loki Patera on moon Io (artist's concept; 0:18). [1] Map of temperature and crust age of Loki Patera obtained by the Large Binocular Telescope. Loki Patera / ˈ l oʊ k i ˈ p æ t ə r ə / is the largest volcanic depression on Jupiter's moon Io, 202 kilometres (126 ...
Highest Resolution image of Surt, acquired by Voyager 1 on March 5, 1979. Surt is an active volcano on Jupiter's moon Io.It is located on Io's Jupiter-facing hemisphere at Surt consists of an oblong volcanic pit (known as a patera), 75 by 40 kilometres (47 by 25 mi) in diameter, surrounded by reddish sulfur and bright sulfur dioxide deposits to its south and east.
Galileo image of Thor taken in October 2001 [1]. Thor is an active volcano on Jupiter's moon Io.It is located on Io's anti-Jupiter hemisphere at A major eruption with high thermal emission and a large, volcanic plume was observed during a Galileo flyby on August 6, 2001, when the spacecraft flew through the outer portions of the plume allowing for direct sampling.
The names of volcanic features on Io use a combination of a name derived from mythological figures from around the world related to the Sun, fire, volcanoes, thunder, or smithing, places from the Greek mythological story of Io, Dante's Inferno, or from the name of a nearby feature on Io's surface and an approved descriptive term. The ...
An active volcano, it was first studied in 1979 via Voyager stereo imagery to determine its geology, topography, and the source of its eruptions. When first discovered, the mountain reached about one kilometer in height and featured numerous lava flows of either low viscosity or "high eruption rates". [1] It is possibly a liquid sulfur-erupting ...
Fractures that are not under compression stress induced by underlying diapiring processes could serve as conduits through which the melt erupts onto the surface. Meanwhile, in a global view, an anti-correlation between the distributions of mountains and volcanic centers is observed on Io. [1] This may reflect a global convective pattern.
