Olympus Mons (/ əˌlɪmpəs ˈmɒnz, 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. It is Mars's tallest volcano, its tallest planetary mountain ...
The solar system's tallest mountain is possibly the Olympus Mons on Mars with an altitude of 21.9 to 26 km. The central peak of Rheasilvia on the asteroid Vesta is also a candidate to be the tallest, with an estimated at up to between 20 and 25 km from peak to base.
Olympus Mons and its associated lava flows and aureole deposits form another distinct subprovince of the Tharsis region. This subregion is about 1,600 kilometres (990 mi) across. It lies off the main topographic bulge, but is related to the volcanic processes that formed Tharsis. [10] Olympus Mons is the youngest of the large Tharsis volcanoes.
However, the largest volcano on the planet, Olympus Mons, is thought to have formed when the plates were not moving. Olympus Mons may have formed just after the plate motion stopped. The mare-like plains on Mars are roughly 3 to 3.5 billion years old. [72] The giant shield volcanoes are younger, formed between 1 and 2 billion years ago.
Tharsis is a land of great volcanoes. Olympus Mons is the tallest known volcano. Ascraeus Mons and Pavonis Mons are at least 320 km across and are over 10 km above the plateau that they sit on. The plateau is five to four seven kilometers above the zero altitude of Mars. Map of Tharsis quadrangle with major features indicated.
The Tharsis Montes (/ ˈθɑːrsɪs ˈmɒntiːz /) are three large shield volcanoes in the Tharsis region of the planet Mars. From north to south, the volcanoes are Ascraeus Mons, Pavonis Mons and Arsia Mons. Mons (plural montes) is the Latin word for mountain; it is a descriptor term used in astrogeology for mountainous features in the Solar ...
Tharsis is a land of great volcanoes. Olympus Mons is the tallest known volcano in the Solar System; it is 100 times larger than any volcano on Earth. Ascraeus Mons and Pavonis Mons are at least 200 miles across and are over six miles above the plateau that they sit on—and, the plateau is three to four miles above the zero altitude of Mars. [4]
Scaled image showing Olympus Mons, top, and the Hawaiian island chain, bottom. Martian volcanoes are far larger than those found on Earth. Shield volcanoes are not limited to Earth; they have been found on Mars, Venus, and Jupiter's moon, Io. [44] The shield volcanoes of Mars are very similar to the shield volcanoes on Earth. On both planets ...
