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. 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.
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.
Patera is an irregular crater, or a complex crater with scalloped edges on a celestial body. Paterae can have any origin, although majority of them were created by volcanism. The term comes from Latin language, where it refers to a shallow bowl used in antique culture.
