Loki Patera

Loki Patera /ˈloʊki ˈpætərə/ 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.

Loki Patera is located at 13°00′N 308°48′W / 13°N 308.8°W / 13; -308.8. It is named after the Norse god Loki. Amaterasu Patera is located to the north and Manua Patera to the northwest.
