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.
Colour image of Io's trailing hemisphere, highlighting the large red ring around the volcano Pele Pele is an active volcano on the surface of Jupiter 's moon Io . It is located on Io's trailing hemisphere at 18°42′S 255°18′W / 18.7°S 255.3°W / -18.7; -255
The Galileo probe observed a lava curtain erupting from the small patera in the centre of the image, and the lava lake from the larger one above it. Tvashtar Paterae compose an active volcanic region of Jupiter's moon Io located near its north pole. It is a series of paterae, or volcanic craters.
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 ...
Jupiter moon Io volcanic activity (left: December 14, 2022; right: March 1, 2023) This is a list of named volcanic surface features on Jupiter's moon Io. These names have been approved for use by the International Astronomical Union. The features listed below represent a subset of the total known volcanic features on Io's surface with the ...
Animation of eruption from Tvashtar Paterae (Io), taken from imagery from the New Horizons probe in 2007 Lava flow at Tvashtar Paterae. Io, a moon of the planet Jupiter, is the most volcanically active body in the Solar System. [1] Its volcanoes are believed to eject sulfur and sulfur dioxide, as well as basaltic and ultramafic silicate lavas. [2]
Ra Patera is an extraterrestrial volcano located on Io, one of the four Galilean moons of Jupiter. An active volcano , it was first studied in 1979 via Voyager stereo imagery to determine its geology, topography, and the source of its eruptions.
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.
