Olympus Mons (/ ə ˌ l ɪ m p ə s ˈ m ɒ n z, oʊ-/; [4] Latin for 'Mount Olympus') is a large shield volcano on Mars.It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level.
Elysium Mons / ɪ ˈ l ɪ z i ə m ˈ m ɒ n z / is a volcano on Mars located in the volcanic province Elysium, at , in the Martian eastern hemisphereIt stands about 12.6 km (41,000 ft) above its base, [2] and about 14.1 km (46,000 ft) above the Martian datum, [2] making it the third tallest Martian mountain in terms of relief and the fourth highest in elevation.
Whether the shield volcanoes were caused by antipodal impacts like that which produced Hellas, or if it is mere coincidence, is unknown. Elevation profiles along south to north transects across Mars' Hellas basin and the Moon's South Pole-Aitken basin, created with Lunar Quickmap and Mars Quickmap
Using cameras fitted on probes orbiting Mars, researchers have observed morning frost forming inside the calderas of the planet’s volcanoes for the first time. Water frost detected on Mars ...
For example, the tallest volcano on Mars, Olympus Mons, is 550 km across and 21 km high. It is nearly 100 times greater in volume than Mauna Loa in Hawaii, the largest active shield volcano on Earth. Geologists think one of the reasons that volcanoes on Mars are able to grow so large is because Mars lacks plate tectonics.
The three major volcanoes of the region sit on top of a 1700 x 2400 km broad dome. [14] The summit of Hecates Tholus shows evidence of pyroclastic activity. [14] Martian volcanism has been dominated by effusive eruption styles and there is limited evidence to support widespread explosive or pyroclastic volcanic eruptions on Mars. [15]
