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.
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
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.
Some of the largest volcanoes on Mars lie relatively close to the proposed “Noctis volcano.” Shown here: 1) Olympus Mons, the tallest known volcano in our solar system.2) The Tharsis plateau ...
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]
On Venus, volcanic features are very numerous and quite diverse, but, like on Mars, none are known to be currently active. These volcanoes range from several to several hundred kilometers in diameter; a majority of them are shield volcanoes. In addition, Venus has unusual types of volcanoes: pancake domes and scalloped margin domes. Most small ...
Scientists have solved the 200-year-old mystery of the location of a massive volcanic eruption that spewed such a large volume of gases that it blocked sunlight, making the sun appear blue.. The ...
In those events, volcanic ash reached from the Pacific ocean to Canada to Mexico. They tend to reoccur about every 600,000 to 800,000 years , according to the U.S. Geological Survey. The most ...
