Dazhbog Patera is a volcanic feature on Jupiter's moon Io. Named after Dažbog, it has a diameter of 118.36 km. and is located 55.1°N 301.48°W. This volcano is difficult to differentiate from the other volcanoes and geological features in some images of Io. In images from the Voyager spacecraft, this caldera is quite prominent with its dark reddish floor with a darkish halo around the caldera.
