The volcano's shape and profile have been likened to a "circus tent" held up by a single pole that is shifted off center. Its flanks are shallower and extend farther from the summit in the northwestern direction than they do to the southeast. Slopes are steepest near the middle part of the flanks and grow shallower toward the base, giving the flanks a concave upward profile. The average slope on the volcano's flanks is only 5%. īeing a shield volcano, Olympus Mons has a very gently sloping profile. Unlike on Earth, the crust of Mars remains fixed over a stationary hotspot, and a volcano can continue to discharge lava until it reaches an enormous height. ![]() The extraordinary size of Olympus Mons is likely because Mars lacks mobile tectonic plates. Olympus Mons covers an area of about 300,000 km 2 (120,000 sq mi), which is approximately the size of Italy or the Philippines, and it is supported by a 70 km (43 mi) thick lithosphere. The volcano's outer edge consists of an escarpment, or cliff, up to 8 km (5.0 mi) tall (although obscured by lava flows in places), a feature unique among the shield volcanoes of Mars, which may have been created by enormous flank landslides. The summit of the mountain has six nested calderas (collapsed craters) forming an irregular depression 60 km (37 mi) × 80 km (50 mi) across and up to 3.2 km (2.0 mi) deep. The total elevation change from the plains of Amazonis Planitia, over 1,000 km (620 mi) to the northwest, to the summit approaches 26 km (16 mi). ![]() Olympus Mons stands 21 km (13 mi) above the Mars global datum, and its local relief, from the foot of the cliffs which form its northwest margin to its peak, is over 21 km (13 mi) (a little over twice the height of Mauna Kea as measured from its base on the ocean floor). Because the mountain is so large, with complex structure at its edges, allocating a height to it is difficult. The edifice is about 600 km (370 mi) wide. Horizontal comparison of Olympus Mons with PolandĪs a shield volcano, Olympus Mons resembles the shape of the large volcanoes making up the Hawaiian Islands. The craters are notable for being two of several suspected source areas for shergottites, the most abundant class of Martian meteorites. Two impact craters on Olympus Mons have been assigned provisional names by the International Astronomical Union. The western portion of the volcano lies in the Amazonis quadrangle (MC-8) and the central and eastern portions in the adjoining Tharsis quadrangle (MC-9). The volcano is located in Mars's western hemisphere, with the center at 18☃9′N 226☁2′E / 18.650°N 226.200☎ / 18.650 226.200, just off the northwestern edge of the Tharsis bulge. ![]() Its mountainous nature was suspected well before space probes confirmed its identity as a mountain. It had been known to astronomers since the late 19th century as the albedo feature Nix Olympica (Latin for "Olympic Snow"). Olympus Mons is the youngest of the large volcanoes on Mars, having formed during Mars's Hesperian Period with eruptions continuing well into the Amazonian. It is the largest and highest mountain and volcano of the Solar System, and is associated to the Tharsis Montes, a large volcanic region on Mars. Olympus Mons is about two and a half times Mount Everest's height above sea level. The volcano has a height of over 21.9 km (13.6 mi or 72,000 ft) as measured by the Mars Orbiter Laser Altimeter (MOLA). Olympus Mons ( / ə ˌ l ɪ m p ə s ˈ m ɒ n z, oʊ ˌ-/ Latin for Mount Olympus) is an enormous shield volcano on the planet Mars.
