Olympus Mons Summit (THEMIS_IOTD_20251205a)
The circular features in this VIS image are part of the summit of Olympus Mons. Large volcanic craters known as calderas are located at the summits of all the Tharsis volcanoes. These calderas are produced by massive volcanic explosions and collapse. Scarps and extensional features (graben) record multiple stages of caldera collapse at the summit of Olympus Mons. Olympus Mons is the largest volcano in the solar system, reaching heights over 25 km (16 miles) tall from base to summit, with the base covering an area as large as the state of Arizona. For comparison, Mauna Loa is 9 km (5.5 miles) tall measured from its base on the sea floor
This martian scene spans 17 x 261 kilometers (11 x 162 miles). To see where on Mars this area lies, and to download high-resolution versions of the image go to themis.asu.edu/zoom-20251205a
