The volcano has a height of 5.3 km, with the caldera being 10 km wide and 600 m deep. Nighttime infrared (IR) images from THEMIS [1] show previously undescribed wind streaks radial to the summit but centered on the northwest flank. Jovis Tholus is a volcano in the Tharsis region and is about 58 kilometers in diameter. Tharsis Tholus was first mapped as cratered shield material, a unit assigned to all volcanic tholi and paterae in the Tharsis quadrangle ().The same structures were later mapped as volcano of unknown relative age possibly containing a caldera and radial channels (Scott and Tanaka, 1986).Later, Tharsis Tholus was proposed to be a basaltic shield (Hodges and Moore, 1994). The summit caldera is located in the top of the image. ATABYRIS MONS and such a view will best exhibit the meaning of the several names which they applied to it. Tharsis is a land of great volcanoes. At its summit is a large caldera 25 km across. While not the largest of the Tharsis volcanoes, Arsia Mons has the largest caldera on Mars, having a diameter of120 km (75 mi)!
