Mars' Olympus Mons 3 x Height of Mount Everest-The Solar System's Most Massive Volcano

Mars,_Olympus_mons_foggy

Mars, as the images issued by the Phoenix probe show us, is not like the Earth: "It is continuous, seamless and sealess," writes Oliver Morton -Mapping Mars: Science, Imagination, and the Birth of a World. But rising above the Red Planets frequent dust storms is the Olympus Mons -the tallest known volcano and mountain in our solar system. The central edifice of this shield volcano stands 27 kilometers ( 88,580 ft) high above the surface -or three times the elevation of Mount Everest above sea level and 2.6 times the height of Mauna Kea above its base. It is 550 km in width, flanked by steep cliffs, and has a caldera complex that is 85 km long, 60 km wide, and up to 3 km deep with six overlapping pit craters. Its outer edge is defined by an escarpment up to 6 km tall; unique among the shield volcanoes of the Red Planet.

Olympus-mons In 2004 the Express orbiter imaged old lava flows on the flanks of Olympus Mons. Based on crater size and frequency counts, the surface of this western scarp has been dated from 115 million years in age down to a region that is only 2 million years old -very recent in geological terms, suggesting that the mountain may yet have some ongoing volcanic activity.

Mauna Kea on the Hawaiian Islands is an example of similar shield volcanoes on a smaller scale. The extraordinary size of Olympus Mons is likely because does not have tectonic plates. Thus, the crust remained fixed over a hotspot and the volcano continued to discharge lava. (Image above compares the heights of Mount Everest, Maxwell Montes on Venus, and Olympus Mons).

The astronomer Patrick Moore points out that during dust storms, "Schiaparelli had found that his Nodus Gordis and Olympic Snow were almost the only features to be seen.

But only with the Mariner probes could this be confirmed with certainty. After the Mariner 9 probe had photographed it from orbit in 1972, it became clear that the altitude was much greater than that of any mountain found on Earth, and the name was changed to Olympus Mons.

Imagine the eruption of this volcano.

It seems entirely possible that this one volcano (indeed, the largest known volcano in the solar system), erupting over millions of years, has made a significant contribution to the present day Martian atmosphere.

Hoi is de Olympus Mons EEN van de Levende dode Vulkaan (DUS HIJ Kan Nog Ooit uitbarsten van niet)

wow

wow

So you did Everest eh? Good, now you're ready for the eastern walls of Olympus Mons. 17°23'26.69 N 128°57'25.39" W looks challenging enough for you, you can start at 793m elevation and finish at 5642m elevation.

lalalalala this is sooooooooooooooooo cool!

I wonder if red bull would sponsor a climb

3x taller than our everest seems if it errupts in earth what will happen?
