The Jovis Tholus shield volcano is located in the Tharsis region on Mars. Tharsis was one of the most active volcanic regions, near the equator of the Red Planet. This is where most of Mars' volcanoes are located. The DLR-operated High Resolution Stereo Camera (HRSC) on ESA's Mars Express spacecraft imaged this landscape, located at approximately 242 degrees east and 19 degrees north, during Mars Express orbits 21,944 and 22,011. The western edge of the largest volcano on Mars, Olympus Mons, which is approximately 100 kilometres away, can be seen at the left-hand edge of this topographic map.
