[2] To Viracocha Patera's east-northeast is Mithra Patera, and to the northeast is the mountain Silpium Mons. [3]
Io, or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter. Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System. It was discovered in 1610 by Galileo Galilei and was named after the mythological character Io, a priestess of Hera who became one of Zeus's lovers.
Loki Patera is the largest volcanic depression on Jupiter's moon Io, 202 kilometres (126 mi) in diameter. It contains an active lava lake, with an episodically overturning crust. The level of activity seen is similar to a superfast spreading mid-ocean ridge on Earth. It is the largest volcano on Io, producing about 10% of Io’s total thermal emission. Temperature measurements of thermal emission at Loki Patera taken by Voyager 1's Infrared Interferometer Spectrometer and Radiometer (IRIS) instrument were consistent with sulfur volcanism.
Pele is an active volcano on the surface of Jupiter's moon Io. It is located on Io's trailing hemisphere at 18.7°S 255.3°W. A large, 300-kilometer (190 mi) tall volcanic plume has been observed at Pele by various spacecraft starting with Voyager 1 in 1979, though it has not been persistent. The discovery of the Pele plume on March 8, 1979 confirmed the existence of active volcanism on Io. The plume is associated with a lava lake at the northern end of the mountain Danube Planum. Pele is also notable for a persistent, large red ring circling the volcano resulting from sulfurous fallout from the volcanic plume.
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. Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active volcanoes. As of 2024, up to 400 such volcanoes are predicted to exist based on these observations. Io's volcanism makes the satellite one of only four known currently volcanically or cryovolcanically active worlds in the Solar System
Reiden Patera is a volcanic feature on Jupiter's moon Io. It was first detected by the Galileo SSI Team during the spacecraft Galileo's first orbit around Jupiter, initially detected as a hotspot. It was once thought that the activity there had stopped or waned below the limits of the spacecraft's Solid State Imager or Near-Infrared Mapping Spectrometer. However, it was noticed in 2002 that Reiden Patera has darkened considerably since the 24th orbit of Galileo. It has been spouting bright red pyroclastic deposits of its own. It is located at 13.4°S 235.45°W and is 70 kilometers in diameter. It is named after a Japanese thunder god. Asha Patera can be found to the east, and Kami-Nari Patera can be found to the north.
Amaterasu Patera is a patera, a complex crater with scalloped edges, on Jupiter's moon Io.

Egypt Mons is a mountain on Jupiter's moon Io. It is 10 kilometers in height, making it the 11th tallest mountain on Io, and taller than Mount Everest. Although the U.S. Geological Survey gives a diameter of 193.7 kilometers, the Io Mountain Database gives a length of 133.8 kilometers and a width of 146.0 kilometers. It is a Flatiron Massif mountain, meaning it has a rugged, irregular appearance and complex surface morphology. It is 9792 km2 in area and its center located at 41.49°S 257.6°W. It has a steep, north-facing scarp. Egypt Mons is named for Egypt, because that is the place where Io ended her wanderings in the mythology.

Its proximity to Svarog and Viracocha Paterae has been suggested to be evidence for a structural relationship between mountains and calderas on Io.
PateraPAT-ər-ə is an irregular crater, or a complex crater with scalloped edges on a celestial body. Paterae can have any origin, although the majority of them were created by volcanism. The term comes from Latin, where it refers to a shallow bowl used in antique cultures.
