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 ...
Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
These volcanic mountains are often smaller than the average mountain on Io, averaging only 1 to 2 km (0.6 to 1.2 mi) in height and 40 to 60 km (25 to 37 mi) wide. Other shield volcanoes with much shallower slopes are inferred from the morphology of several of Io's volcanoes, where thin flows radiate out from a central patera, such as at Ra Patera .
A volcanic plume has been observed at Masubi by various spacecraft starting with Voyager 1 in 1979, though it has not been persistent like similar Ionian volcanoes Amirani and Prometheus. [2] Masubi is also notable for having one of the largest active lava flows on Io, with an additional 240 km (150 mi) flow forming between 1999 and 2007. [3]

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 ...
Amirani is about the same age as Jupiter, which is around 4.5 billion years old.It is surrounded by the Gish Bar Patera. [4] Within the mountains of the crater, Amirani lies at the center of a frozen sulphuric lava field that consists of a half-circle shaped, 37 kilometer wide volcanic pit, which is connected to a 330 kilometer compound lava flow by a narrow channel.
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.
