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.
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.
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 ...

An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future.

A massive volcano may be hiding in plain sight on Mars, according to a report from two researchers that’s making waves in the planetary science community.
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.
