These volcanoes are strikingly similar to shield volcanoes on Earth. Both have shallow-sloping flanks and summit calderas. The main difference between Martian shield volcanoes and those on Earth is in size: Martian shield volcanoes are truly colossal. For example, the tallest volcano on Mars, Olympus Mons, is 550 km
Olympus Mons is the youngest of the large volcanoes on Mars, having formed during the Martian Hesperian Period with eruptions continuing well into the Amazonian Period. It has been known to astronomers since the late 19th century as the albedo feature Nix Olympica (Latin for "Olympic Snow"), and its mountainous nature was suspected well before ...

Scientists have already cataloged and named more than a dozen volcanoes on Mars, including Olympus Mons, the tallest known volcano in our solar system. Olympus Mons, standing at at 25 kilometers ...
Scientists have never recorded an active volcano eruption on the surface of Mars. [65] Searches for thermal signatures and surface changes within the last decade have not yielded evidence for active volcanism. [66] On October 17, 2012, the Curiosity rover on the planet Mars at "Rocknest" performed the first X-ray diffraction analysis of Martian ...
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.
Tharsis (/ ˈ θ ɑːr s ɪ s /) is a vast volcanic plateau centered near the equator in the western hemisphere of Mars. [note 1] The region is home to the largest volcanoes in the Solar System, including the three enormous shield volcanoes Arsia Mons, Pavonis Mons, and Ascraeus Mons, which are collectively known as the Tharsis Montes.
Elysium contains the major volcanoes Elysium Mons, Albor Tholus and Hecates Tholus. Another more ancient shield volcano, Apollinaris Mons, is situated just to the south of eastern Elysium Planitia. Within the plains, Cerberus Fossae is the only Mars location with recent volcanic eruptions.
