Loki Patera /ˈloʊki ˈpætərə/ is the largest volcanic depression on Jupiter's moon Io, 202 kilometres (126 mi) in diameter.[2] It contains an active lava lake, with an episodically overturning crust.[3] The level of activity seen is similar to a superfast spreading mid-ocean ridge on Earth.[4] It is the largest volcano on Io, producing about 10% of Io’s total thermal emission.[5] 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.[6]
Loki Patera is located at 13°00′N 308°48′W / 13°N 308.8°W[7]. It is named after the Norse god Loki.[7] Amaterasu Patera is located to the north and Manua Patera to the northwest.[citation needed]
