It's something like 140 million miles away.Recently, Calbuco volcano in Chile erupted. McGovern, P.J. (2010). Levees are quite common to lava flows on Mars. Terrestrial Analogs to the Calderas of the Tharsis Volcanoes on Mars in. Is Olympus Mons taller than Mars atmosphere? It's a shield volcano, just like the Hawaiian islands. Olympus Mons: A Primary Target for Martian Biology. "Monster Martian volcano unlike anything on Earth, scientists say (opens in new tab)". Olympus Mons is a very large shield volcano on the planet Mars. (2010). The layering of the ice is easily visible due to the dust that is dep Marte Vallis, located in Amazonis Planitia, is broad and shallow. Most of the water has evaporated away, and whatever little water is present is present as ice beneath the surface. The astronomer Patrick Moore pointed out that Schiaparelli (18351910) "had found that his Nodus Gordis and Olympic Snow [Nix Olympica] were almost the only features to be seen" during dust storms, and "guessed correctly that they must be high".[41]. Mt. When NASA's Mariner 9 arrived at the red planet in 1971, it was able to pick out the tops of the volcanoes above the storms. In 2021, a group of students from the Royal Institute of Technology in Stockholm, Sweden, put together a proposal for a mission (opens in new tab) they believed might be feasible by 2042. It had been known to astronomers since the late 19th century as the albedo feature Nix Olympica (Latin for "Olympic Snow"). Is iPhone 8 Waterproof? Would Happen If Olympus Mons Erupted? Olympus Mons is a mountain located on the planet Mars and it is believed to be the tallest mountain in our entire solar system. Strange indeed, but this is what happens on terrestrial volcanoes. The tephra from an eruption of Olympus Mons would also impact Earths magnetic field and atmosphere. This would cause the Earth to freeze over as the climate changed. The term for all fine-grained volcanic products fragmented during explosive eruptions. Like the basalt volcanoes on Earth, Martian basaltic volcanoes are capable of erupting enormous quantities of ash. We're aiming to achieve uninterrupted service wherever an earthquake or volcano eruption unfolds, and your donations can make it happen! Science has given us no reason to believe there is water on Venus, and if there was it would surely be evaporated before it could do much. Visit our corporate site (opens in new tab). If there was a HUUUUGE volcanic eruption on OM, it's projectile (rock, ash, etc) would need to be shot out at about 20,000 mph for a sustained amount of time in order to escape mars' gravity. Friction was higher in that direction because the sediments were thinner and probably consisted of coarser grained material resistant to sliding. Olympus Mons is the youngest of the large volcanoes on Mars, having formed during Mars's Hesperian Period with eruptions continuing well into the Amazonian. For comparison, Mauna Loa is 9 km (5.5 miles) tall measured from its base on the sea floor. That's about two and a half times the height of Mount Everest. Press question mark to learn the rest of the keyboard shortcuts. "Highest and Lowest Points on Mars (opens in new tab)" Geology.com. This inhibition of southeasterly basal spreading in Olympus Mons could account for the structural and topographic asymmetry of the mountain. [30] Using geometric relationships of caldera dimensions from laboratory models, scientists have estimated that the magma chamber associated with the largest caldera on Olympus Mons lies at a depth of about 32km (105,000ft) below the caldera floor. Olympus Mons actually erupted relatively recently geologically speaking, in the last few million years. [24] Although the average Martian surface atmospheric pressure is less than one percent of Earth's, the much lower gravity of Mars increases the atmosphere's scale height; in other words, Mars's atmosphere is expansive and does not drop off in density with height as sharply as Earth's. The region spans 2,500 miles across the surface of Mars and contains 12 large volcanoes that are up to 100 times larger than any volcanoes on Earth. There are six calderas at the summit, which together stretch to the total size of the Yellowstone one. Olympus Mons rises three times higher than Earth's highest mountain, Mount Everest (opens in new tab), whose peak is 5.5 miles (8.8 km) above sea level. Soderblom, L.A.; Bell, J.F. 8 Best Family Resort In The Us Virgin Islands: Fun For All Ages! Olympus Mons (20N,135W). Scientists believe that Olympus Mons is what is known as a shield volcano. On Earth this is caused by ocean water seeping into the crust or by heating of mantle material at the boundary between the mantle/outer core (Mantle plumes). Create an account to follow your favorite communities and start taking part in conversations. The massive Martian mountain towers high above the surrounding plains of the red planet, and may be biding its time until the next eruption. When a volcano erupts, it releases ash and rocks into the atmosphere. 3. This liquid magma builds up under the crust, creating immense pressure, until it finally cracks the crust open and erupts out as lava. Tephra is so light that it would have no significant effect on the orbits of comets and asteroids, but it could cause these bodies to collide with each other if they were not already headed toward each other. 42nd Lunar and Planetary Science Conference. The volcanoes on Venus have played a big part in what it is today, a barren hell scape. Join our Space Forums to keep talking space on the latest missions, night sky and more! Even in the case of mantle plumes, you have got to penetrate like 70 km of rigid crust, and 500km of lithosphere. When tephra is released into Earths atmosphere, it acts as a blanket that blocks out sunlight from reaching the surface of the Earth. The actual impact of these events is negligible. Even mantle plumes don't stand a chance. Mars, on the other hand, is too small for plate tectonics. The longer, more shallow northwestern flank displays extensional features, such as large slumps and normal faults. "Olympus Mons: The Biggest Hotspot in the Solar System (opens in new tab)". [26] These ages are very recent in geological terms, suggesting that the mountain may still be volcanically active, though in a very quiescent and episodic fashion. Olympus Mons is a shield volcano, which means it oozes huge amounts of lava, rather than simply blowing its top in a catastrophic eruption. Its diameter spreads 370 miles (600 kilometers) from edge to edge. EVEN THEN whatever tiny rock made it out. Orbital view of Mars' Olympus Mons volcano. 6. Additionally, see the mountain's caldera close-up on ESA's website (opens in new tab). It stands about 1,200km (750mi) from the other three large Martian shield volcanoes, collectively called the Tharsis Montes (Arsia Mons, Pavonis Mons, and Ascraeus Mons). [12] Because the mountain is so large, with complex structure at its edges, allocating a height to it is difficult. Magma that is very viscous produces explosive eruptions because the gases become trapped in the thick fluid. Venus still has water, but it is not present in the liquid form. Since there's no surface water on Mars, it isn't as easy to quantify terrain heights there as it is on Earth. We believe in empowering our readers with the knowledge they need to make the most of their lives. Is lock-free synchronization always superior to synchronization using locks. Press J to jump to the feed. Olympus Mons is a shield volcano, a volcano that is characterized by very gentle eruptions. Io's magma is caused by gravitational tidals forces which decompress Io's mantle to produce magma. The meteorites were blown into space when a massive rock crashed into the planet 11 million years ago. Outer slopes of Mt Olympus volcano in background (October 31, 2012, NASA image), Roaming icy fields on Antarctica (ANSMET), Meteorite from Mars found in Antarctica (ANSMET), Basalt meteorite (sample nr BET-M7-0104) discovered in a remote part of the East Antarctic Ice Sheet (ANSMET), Sketch of the trajectory of a volcanic bomb from Mt Olympus volcano on Mars until impact on Earth as meteorite (image: OPEC / NASA / VolcanoDiscovery), Architect's conception of the new MOVO (Mount Olympus Volcano Observatory). Although it has taken billions of years to form, some regions of the mountain may be only a few million years old, relatively young in the lifetime of the solar system. This THEMIS visible image shows a close-up view of the ridged plains in Hesperia Planum. What would the average terraformable planets look like? From Jupiter's moon Io, the most volcanic place in the solar system, to Olympus Mons on Mars, check out 10 amazing volcanoes in the planets and moons of the star system we call home. The depth of this depression is greater on the northwest side of the mountain than on the southeast side. This map shows unprecedented detail of local variations in Mars' gravitational pull on orbiters. Barbara Botts is a news writer. Your email address will not be published. so, ZERO effect. ; Harris, A.J.L. Olympus Mons is a shield volcano, the largest known in the solar system. Can you provide citations claiming, in effect, that liquid rock can only exist in the presence of water? Freie Universitt Berlin (2016). The average slope on the volcano's flanks is only 5%. Olympus Mons ( /lmps mnz, o-/;[4] Latin for Mount Olympus) is a large shield volcano on Mars. Mars' Olympus Mons is the largest volcano in the solar system. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? Olympus mons is what is known as a shield volcano. The volcanoes in Tharsis Montes are so large that they tower above the seasonal Martian dust storms. It has a height of nearly 25 km (16 mi) above Mars'surface and a diameter of 600 km, making it about as large as Arizona. The explosion was caused by a nuclear bomb that was thrown into the caldera during a . As magma chambers beneath the calderas emptied of lava, most likely during an eruption, the chambers collapsed, no longer able to support the weight of the ground above. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C. We imagine Olympus Mons changing from non-explosive to explosive as it grew in height (lower air pressure at the top) and the Martian atmosphere was lost aftr the loss of the planet's magnetic field. Its crater is comparable in width to Paris. But Olympus Mons stands above the rest, reaching an astonishing height of 16 miles (26 kilometers), or around three times as tall as Mount Everest. The Hawaiian Islands (opens in new tab), for instance, formed as a plate drifted over a hot spot. Olympus'outline with France, Curiosity rover in Gale Crater, on Mars, collecting a dusty lava bomb sample. It's also got girth. Volcanoes occur mainly due to tectonic activity (Ignoring mantle plumes for now), more specifically, the pushing down of the oceanic-plate, by the above land-plate. It likely became so large because Mars does not have tectonic plates. Water-ice insulated by surface dust may exist near the top of the volcano. University of Glasgow (2017). It was enough to reroute rivers and change the planets climate. [3] The summit of the mountain has six nested calderas (collapsed craters) forming an irregular depression 60km (37mi) 80km (50mi) across[13] and up to 3.2km (2.0mi) deep. Thanks for adding a link to Olympus mons on Wikipedia, stranger! is there a chinese version of ex. Save my name, email, and website in this browser for the next time I comment. By signing up you may also receive reader surveys and occasional special offers. zero effect. It is 624 km in diameter, 22 km high, and the cone has a 6km high cliff around most of its base. The aureole consists of several large lobes. A mantle of fine dust obscures the underlying bedrock, possibly making rock samples hard to come by and likely posing a significant obstacle for rovers. 2023 Info Rain | All Rights Reserved |. mostly due to ash. This raises the intriguing possibility that the volcano is still active, and may erupt again in the future. These results point to the surface being largely composed of basalts and other mafic rocks, which would have erupted as low viscosity lava flows and hence lead to the low gradients on the surface of the planet. This giant shield volcano is almost entirely constructed of basalt lava flows. A half century from now, one of Elon Musk's current space competitors may be running tours to Olympus Mons, our solar system's largest known volcano. The edifice is about 600km (370mi) wide. rev2023.3.1.43269. Mars would briefly have a thicker atmosphere, and there would be a big ash plume. Stay up to date with what you want to know. Earths biggest volcanoes are also shield volcanoes. If water-saturated zones still exist in sediments under the volcano, they would likely have been kept warm by a high geothermal gradient and residual heat from the volcano's magma chamber. Purdue University (2017). To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Additionally, because these particles are so fine, they can travel large distances in space before they are destroyed by radiation or other elements in space. This false-color map shows the area within Gale Crater on Mars, where NASA's Curiosity rover landed on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT) and the location where Curiosity collected its first drill NASA's 2001 Mars Odyssey orbiter arrived at Mars on Oct. 24, 2001. This could have many effects, including disrupting communication between the two planets and even causing damage to satellites orbiting each planet due to magnetism being disrupted in space near them. Over time, these basins received large volumes of sediment eroded from Tharsis and the southern highlands. The Martian atmosphere would quickly become 10 times thicker than normal, and the surface would become too cold to sustain life, although the ice caps would melt and create a thick, dense atmosphere that would not allow the particles from the eruption to escape. Embed this resource by pasting the following code into your website: Managed by the Mars Exploration Program and the Jet Propulsion Laboratory for NASAs Science Mission Directorate, Dr. Bill Boynton, Principal Investigator for the Gamma Ray Spectrometer suite of instruments Image credit: NASA/JPL. In addition, the magma chambers are thought to be much larger and deeper than the ones found on Earth. 2023 Astronomy Calendar & Observer's Handbook, Learning to grow food on Mars could transform food production on Earth, Astronomers discover a formation on Mars that resembles a bear, NASA pulls plug on Mars InSight lander, ending 4-year mission, Perseverance drops off first Mars sample for future return to Earth, With Mars at opposition, target deep-sky objects in Taurus, Megatsunami swept over Mars after devastating asteroid strike, Astronomy Magazine Collection 2016-2020 DVD-ROM. The tephra released by an eruption of Olympus Mons would also impact both planets magnetic fields. as in example? The volume contained by Olympus Mons is about a hundred times that of Mauna Loa, and the entire Hawaiian island chain (from Kauai to Hawaii) that houses it could fit inside its Martian counterpart. Lava is believed to have flowed from this large volcanic vent in the Tharsis region on Mars. Scientists think that the lower surface gravity of the red planet, combined with higher eruption rates, allowed for the lava on Mars to pile up higher. Required fields are marked *. Earth has a thinner crust, due to a larger mantle. [40], Olympus Mons and a few other volcanoes in the Tharsis region stand high enough to reach above the frequent Martian dust-storms recorded by telescopic observers as early as the 19th century. New comments cannot be posted and votes cannot be cast. This image from NASA's 2001 Mars Odyssey spacecraft shows part of the margin of the north polar cap and the surrounding plains. Dating The Most Recent Episodes of Volcanic Activity From Mars's Main Volcanic Calderae (sic). The particles absorb incoming light, preventing a lot of it from reaching the surface where it would act as heat for life on Earth. (Dont ask how). Basically. If there was a HUUUUGE volcanic eruption on OM, it's projectile (rock, ash, etc) would need to be shot out at about 20,000 mph for a sustained amount of time in order to escape mars' gravity. A continent sized land formation on a water planet with impassable mountains all around the edges and a salty sea in the middle, Rename .gz files according to names in separate txt-file, Theoretically Correct vs Practical Notation. A wide, annular depression or moat about 2km (1.2mi) deep surrounds the base of Olympus Mons and is thought to be due to the volcano's immense weight pressing down on the Martian crust. Maintaining our website and our free apps does require, however, considerable time and resources. New comments cannot be posted and votes cannot be cast. Only about 1/6 of the country, plus small parts of Argentina and Uruguay felt any effect. The caldera of Olympus Mons is the depression near the top center of the image. Tephra is made up of fine particles that are less than 2 microns in diameter, which is about one-tenth the size of human hair. Lava flows on Olympus Mons with older and younger flows labeled, as viewed by HiRISE during the HiWish program. [11], As a shield volcano, Olympus Mons resembles the shape of the large volcanoes making up the Hawaiian Islands. Formation and Evolution of Surface and Subsurface Structures within the Large Caldera of Olympus Mons, Mars. The 10 sample tubes being dropped on Mars surface so they can be studied on Earth in the future carry an amazing diversity of Red Planet geology. John Brady at Astronomy Central shows, in the image below, what this gargantuan feature would look like if it were on the continent of North America it would completely cover the state of Arizona! What geologic processes would create an unstable cliff on which a city is built? They are the 15.6-kilometre-diameter (9.7mi) Karzok crater (1825N 22805E / 18.417N 228.083E / 18.417; 228.083) and the 10.4-kilometre-diameter (6.5mi) Pangboche crater (1710N 22625E / 17.167N 226.417E / 17.167; 226.417). The cooler, outer margins of the flow solidify, leaving a central trough of molten, flowing lava. When lava flows to the surface, it continues to pile up in a single spot. Download a PDF of the Explore Mars Sticker. She loves all things space and astronomy-related, and enjoys the opportunity to learn more. (Image credit: NASA/JPL-Caltech/Univ. While we don't have any rovers exploring the mountains right now, planetary scientists manage to probe the volcanoes with rocks from Earth. The high altitude of Olympus Mons makes a parachute-assisted descent difficult in the tenuous atmosphere, while the presence of loose dust would cause maneuvering problems for rovers. Olympus Mons is the largest volcano in the solar system, reaching heights of over 40 km (25 miles) tall from base to summit, with the base covering an area as large as the state of Arizona. A cliff, or escarpment, surrounds the outer edge of the volcano, reaching as high as 6 miles (10 km) above the surrounding area.Dec 8, 2017. It is associated with the Tharsis Montes, a large volcanic region on Mars. [15] Olympus Mons covers an area of about 300,000km2 (120,000sqmi),[16] which is approximately the size of Italy or the Philippines, and it is supported by a 70km (43mi) thick lithosphere. Thanks, Robert. If you set Olympus Mons on top of the United States, it would cover the entire state of Arizona. There is no way Olympus Mons can erupt, @ArktourosUltorMaximus7600 After reading your answer and doing some quick research, I believe your comment, above, is a bit wrong. Olympus Mons is as big around as the state of Arizona (about 400 miles) and rises 16 miles above the Martian surface almost three times taller than Mt. Hobart M. King, PhD, RPG. This would cause the Earth to freeze over as the climate changed. [28] Calderas are formed by roof collapse following depletion and withdrawal of the subsurface magma chamber after an eruption. Its eruptions seem mostly to be leveed lava channels, similar to what we see on Hawaii. The meteorites born from the volcano actually show signs of minerals that form as water passes through rock, which suggests water was flowing on Mars as recently as 1.3 billion years ago. Everest might be the tallest mountain on Earth, but it's nothing compared to the tallest volcanic mountain in the solar system, Olympus Mons on our red cousin Mars. The simple answer would be that it wouldn't do much. Volcanoes like Olympus mons would create many large lava flows and would have limited amounts of explosive eruptions Share Improve this answer Follow answered Jan 13 at 16:31 HomegrownPotatoes 1,249 6 21 3 This movie shows three views of the Martian moon Phobos as viewed in visible light by NASA's 2001 Mars Odyssey orbiter. In fact, three other large volcanoes near Olympus Mons are similarly gigantic; if only one of the four volcanoes in the region existed, it would be the tallest feature in the solar system. These fine particles would not only block out sunlight but also absorb water vapor and carbon dioxide. Olympus Mons actually erupted relatively recently geologically speaking, in the last few million years. And How You Can Cut Your Costs, Is Jordan Store Legit? Create an account to follow your favorite communities and start taking part in conversations. Ius Chasma is unique from the other chasmata of Valles Marineris in possessing mega gullies on both sides of the chasma. NASA's spacecraft on and orbiting the Red Planet reveal thesimilarities to and differences from how we experience winter on Earth. That suggests there has been at least some explosive activity. And how would you get magma to form in the first place without water (which by the way, is scarce on Mars)? And in Olympus Mons case, the craters on its surface are also only around 200 million years old, which implies this volcano was active surprisingly recently, at least to a limited extent. This melts the mantle in turn, which Olympus mons is still partially connected to. [37], It has been speculated that the detachment along the weak layers was aided by the presence of high-pressure water in the sediment pore spaces, which would have interesting astrobiological implications. 4. [35] Why opposite sides of the mountain should show different styles of deformation may lie in how large shield volcanoes grow laterally and in how variations within the volcanic substrate have affected the mountain's final shape. I can't find it. On Mars, however, there is not much water. The Odyssey spacecraft was launched toward Mars on April 7, 2001 from Cape Canaveral, Florida. They are nearly 700 km apart, and each reaches nearly the same height as Olympus Mons (~25 . Numerical models of particle dynamics involving lateral differences in friction along the base of Olympus Mons have been shown to reproduce the volcano's present shape and asymmetry fairly well. Scientists estimate that the last time Olympus Mons erupted lava onto the Martian surface was between 20 and 200 million years ago around the same time that dinosaurs roamed the Earth. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. Everest. If Olympus Mons erupted, the consequences would be devastating. 40th Lunar and Planetary Science Conference. The explosivity of a volcanic eruption is determined by the magma that erupts. This mechanism has long been cited as an explanation of the Olympus Mons aureole deposits (discussed below).[38]. It is almost three times taller than Mount Everest! Related: Origins, variants and eruptions of space volcanoes. Instead of a chain of volcanic islands, large volcanoes such as Olympus Mons form. The high elevations preclude parachute-assisted landings because the atmosphere is insufficiently dense to slow the spacecraft down. In fact Mars' crust is 24-72 km thick, with a 500 km thick lithosphere. Due to the reduced gravity of Mars compared to Earth, there are lesser buoyant forces on the magma rising out of the crust. Shield volcanoes are classified as very large with broad slopes. They are very large with a low, dome-like profile. "Mystery Solved Regarding Largest Volcano in the Solar SystemScientists at the Institute of Geological Sciences at Freie Universitt Berlin Succeeded in Simulating the Evolution of the Mars Volcano Olympus Mons (opens in new tab)". "Our research raises the possibility that the opposite happens on Mars; a plume might move beneath the stationary crust.". Now, as water enters the mantle, it catalyses a series of reactions, that causes the mantle material to decompress and become a liquid, i.e. Numerous thin lava flows are visible. Odyssey's Three Views of Phobos in Visible Light, Great Convergence of Spacecraft around Mars, Challenges of Getting to Mars: Aerobraking, Local Variations in the Gravitational Pull of Mars, Curiosity Communicates with Help From Its 'Friends', NASA's Perseverance Rover Completes Mars Sample Depot, NASA's Perseverance Rover Deposits First Sample on Mars Surface, NASA Retires InSight Mars Lander Mission After Years of Science, NASA's Perseverance Rover to Begin Building Martian Sample Depot, NASA and ESA Agree on Next Steps to Return Mars Samples to Earth, NASA's InSight 'Hears' Its First Meteoroid Impacts on Mars. The crust and mantle traveled about 20, moving from the polar regions toward the equator. as well as other partner offers and accept our, NASA/MOLA Science Team/ O. de Goursac, Adrian Lark. But what would happen if it were to erupt? A big volcano does not equate to big eruptions. The small raised channel is one mode of lava emplacement where the flow builds up cooling levees along both sides of the channel. What would happen to a world with three moons? 7. Byrne, P.K. We've added a "Necessary cookies only" option to the cookie consent popup. This would trap the particles in the Martian atmosphere and increase the amount of cooling. The atmosphere would be significantly altered by the eruption. Observations of the planet from Mariner 9 confirmed that Nix Olympica was a volcano. Snow falls and ice and frost form on Mars, too. Even so, if Martian space tourism gets going in the coming decades, Olympus Mons could become a prime target for adventurous holiday-makers. However, Earths plate tectonics also spread magma out, which keeps terrestrial volcanoes from indefinitely growing taller. NY 10036. The difference is that the Hawaiian magma plume moves over time. Some scientists have used the High Resolution Stereo Camera installed on the European Mars Express orbiter to create a mosaic and terrain model (opens in new tab) of the volcano. As the volcano grew through lateral spreading, low-friction detachment zones preferentially developed in the thicker sediment layers to the northwest, creating the basal escarpment and widespread lobes of aureole material (Lycus Sulci). Snow and ice deposits above the base of the shield could result in such glaciers. [23] Even so, high-altitude orographic clouds frequently drift over the Olympus Mons summit, and airborne Martian dust is still present. Robbins, S.J. That would also be cool. While it's debated whether or not there is any tectonic activity still taking place on Mars, there's no doubt that it . 40th Lunar and Planetary Science Conference, Abstract #1527. Here we go. [14] The volcano's outer edge consists of an escarpment, or cliff, up to 8km (5.0mi) tall (although obscured by lava flows in places), a feature unique among the shield volcanoes of Mars, which may have been created by enormous flank landslides. [10] The craters are notable for being two of several suspected source areas for shergottites, the most abundant class of Martian meteorites. 8 Best All-Inclusive Resorts In Montego Bay Jamaica For Adults: The Best All-Inclusive Vacation Spot. [14] Slopes are steepest near the middle part of the flanks and grow shallower toward the base, giving the flanks a concave upward profile. Potential springs or seeps around the volcano would offer exciting possibilities for detecting microbial life. The volcano has a height of over 21.9km (13.6mi or 72,000ft) as measured by the Mars Orbiter Laser Altimeter (MOLA). Press question mark to learn the rest of the keyboard shortcuts. This is essentially how Olympus Mons is thought to have come into being. +1. The volcano has a height of over 21 km (13.6 mi or 72,000 ft) as measured by the Mars Orbiter Laser Altimeter (MOLA). Please see the THEMIS Data Citation Note for details on crediting THEMIS images. The complex central caldera of Mars' Olympus Mons. Olympus Mons rises three times higher than Earth's highest mountain, Mount Everest (opens in new tab), whose peak is 5.5 miles (8.8 km) above sea level. Reddit and its partners use cookies and similar technologies to provide you with a better experience. A cliff, or escarpment, surrounds the outer edge of the volcano, reaching as high as 6 miles (10 km) above the surrounding area. The tephra from an eruption of Olympus Mons would also impact Earths magnetic field and atmosphere. Any theories? This indicates that the uppermost layer of lava is relatively young, with the last eruption occurring as recently as 25 million years ago.
