Instead, that title would go to the fissure system in Cerberus Fossae which erupted between 50,000 - 60,000 years ago.

With you 100% on this one... I've been waiting for this video to be done!!

This video was simply out of this world! Here's an interesting fact about Olympus Mons. The mountain is so massive that if you stood at the base of the mountain, then it's impossible to see the summit of the mountain, due to the curvature of the planet!

I wonder if Olympus Mons is affected by one other factor that also affects the heights our volcanos can reach; crustal sag. Mars, being smaller than Earth, may have a relatively thicker crust, thanks to the fact it will have cooled more quickly than Earth. Even so, the sheer size of the volcano must be pressing down on the crust of the planet in that area, causing a sizeable depression in which it sits. As tall as Olympus Mons is, I wouldn't be too surprised to learn that it's much taller thanks to the fact it's mass has created a big pit for it to nestle in!

Very interesting! I'd never thought before about why this volcano was so tall compared to those on Earth, a much larger planet. Thank you!

That was a cool video. One point I'd like to add. The reason why those hotspots existed in the first place is being discussed. One interesting hypothesis is that on the Martian antipode of that complex of volcanoes, there are some features indicating an asteroid impact. Said impact would have created shockwaves like when a rock lands in a pond. Only imagine that pond to be spherical. The shockwave would spread around the surface, and due to the sphere-like shape of a planet, it would ultimately focus back in together on the other side of the planet, creating a concentration of energy on that spot. That concentration of energy may be what caused the hotspot to appear, thus allowing those volcanoes to form.

@stargazer5784

25 күн бұрын

The antipodal point of a very major impact, as is seen on Mercury due to the Calloris basin impact, will be riddled with very distinctive surface features that aren't seen on Mars. Olympus Mons and the other huge volcanoes in the region sit atop what is called the Tharsis dome, a very large area of dramatically higher elevation than the rest of the planet. As the man also said about the creation of the volcano, this entire area was uplifted by a huge stationary mantle plume. Immediately east of Olympus Mons are three more gigantic volcanoes born of the same hotspot, but their names escape me. I'm an old retired amateur astronomer, and it's been a long time since I looked at a map of Mars. This is frankly, old news to me, but this guy does a great job explaining things like this to the layman, and I enjoy watching his videos. Cheers.

Thanks as always, Geology Hub! Olympus Mons is jut an impressive geological feature! I did not know that Olympus Mons actually had flank eruptions many hundreds, even thousands of kilometers away. I wonder if you can cover Alba Mons, given that is is much wider, but not taller, than Olympus Mons.

Olympus Mons: "Hold my magma." One day within the next 30 years there will likely be humans studying Olympus Mons during a Mars mission. I've had KZread Premium for a few years now. Well worth the cost.

Wow! Thank you for this info on Olympus Mons! I Love anything about Space and the Solar System, so this was wonderful to see!

finally! been waiting for this one.

Luv a little dose of planetary geophysics. How about a video on Io - Jupiter’s moon and the most volcanically active body in our SS.

Great video as always. The following is presented as discussion, not any sort of critique. Thank you for your hard work! So, If I understand the mechanisms correctly, Mars would probably still have an atmosphere if Olympus Mons was capable of producing another eruption. Our magnetosphere is a direct result of the molten metal core of our planet. That heat is in large part what produces the magma which erupts onto the surface here. The patchy, orders of magnitude weaker field that is found on Mars is magnetized crustal material and meteoritic impacts. Nothing large or structured enough to prevent the solar wind from stripping the atmosphere off the surface of the planet. That lack of an orderly, planetwide magnetic field is a pretty good indication that the core of Mars is cold, which means no magma. This is also why we will never terraform Mars, since any effort to produce an artificial atmosphere will be defeated by the solar wind. We can and probably should colonize Mars, but it's never going to be another Earth.

That we know of. Which is awesome, because out there somewhere in the universe, odds are there is one that is godlike in its mass. Love vids on Olympus Mons.

Can you please do the other Lesser known volcanoes of mars? And a video on Venus would be interesting

Long time viewer here, this was really cool, appreciate your content man keep it up! I also really am excited for exploration on the mars planet. The fact that this was an island and has obvous erosion on the island meaning water as well as other evidence found with the rover is fastenating. I still feel I was born too early for space travel, but I do hope we can find out some of its secrets in my life time.

Thanks for all the hard work on these videos! KZread Premium is the only subscription i feel im getting my moneys worth. tho wish the creators i watch got a slightly bigger piece

It has been suggested that lava tubes throughout OM would make for cheap and and relatively safe (shielded from radiation) living spaces. Thanks! I've been hoping you would cover this (Had the Nat Geo Mars map on my wall for years growing up). I didn't know the base erosion was caused by hydro (and not H.Y.D.R.A. after all 😜). I had always thought breakage from thermal cycling (like the calving of glaciers), but water makes way more sense. 😎 Well, as they say, learn 42 every day. 🖖👽👍👍👍

Wow. We all should go there.

Darn, I already have it. I love this channel though. Thank you!

This was great. Love to see one about the other tharsis volcanic features Ascraeus mons, pavonus mons and arsia mons👍

I have a hypothesis that the processes directly involved with Olympus Mons are directly related to the collapse of the martian magnetic field

Also, the land around the volcano has subsided several thousand feet, even with sediment fill in.

Now im wondering about the volcanoes of Venus and Io now....

I remember reading somewhere that Mars had a tiny bit of oceanic crust. Is this true? If so, where is it, why did it form, and how do we know?

If I remember correctly Olympus Mons wasn't always the biggest. That would go to alba mons although it has since gone completely extinct and mostly eroded away. Another interesting note is that most of the volcanoes on Mars are antipodal to large impact craters.

@filonin2

25 күн бұрын

Alba Mons did not erode away from being taller than Olympus Mons as erosional process on Mars are minimal and there is no evidence it was ever that tall. It is so spread out because it had very low viscosity lava, as evidenced by it's very long lava flows and wide, spread out appearance. Thick pancake batter vs. thin. Right on the wikipedia BTW.

I'm curious as to how they know the eruptions 2000km away originated from Olympus Mons. No surface rovers have visited either area so how could they test for a chemical match between the rocks at each location? Or is there another way they linked the different locations?

If I remember correctly there is evidence that at one point Olympus Mons was a Tuya before transitioning into a shield volcano after the deglaciation of Mars.

That's a pretty bold statement. Perhaps there's a bigger one on an exoplanet.

Wild!

What I wouldn't give to see a Mars eruption in my lifetime. That or a supernova (which is relatively more likely).

Can you do something on the known geology of Europa?

How does it's age compare with the impact crater at the antipodal location?

Not a volcano

What are your thoughts about the origin of Olympus Mons being the impactor that created Hellas Planitia?

Sometimes i find it amusing that my friends or random folk on the internet don't grasp "recent" like geologists and enthusiasts do. Example, was detailing Isarog's last eruption about 2,000 years ago or something, and calling it recent and classifying her as active made someone say she is extinct as she has not erupted in a while... 😅 Needless to say i had to pull up some references. Digression, some less savory individuals buy land close to volcanoes because honestly the view is beautiful. But there is always the risk of property damage if not total destruction, hence insurance won't cover these plots of land or something to that effect. What these characters do is suppress research or data findings that put their property at risk and therefore crash the value and insurance companies won't touch it with a 5-meter pole. It all boils down to money. Tagaytay is a stellar example. Lots of resorts and private houses. On the caldera rim of Taal, a volcano with a very violent history and penchant for unpredictability.

Probably not the tallest in the universe though!! Crazy

the more we expolore the heavens, the more we learn seems like this may eventually turn out to be a molehill depending on what else is found

If one looks at the largest impact crater on Mars, it is a very large crater, large enough to put into play kinetic forces. Kinetic forces such as exhibited by the desktop balls novelty that swings back and forth transferring kinetic energy from the inner balls to the outer balls. The effect in this case of a planet is that the molten core of Mars was what got kinetically transferred. Mars core is now beneath the only volcanic features of Mars. From a liquid core and a semi-molten malleable mantle. The addition of a large crack across Mars which likely drained Mar's oceans onto that mantle and core, causing Mars, to go "POOF", the entire planet surface recoiled like a trampoline from the explosion, the contact of an ocean draining upon its core. Tectonics on Mars was either halted or could not possibly develop further beyond such an event. And it also turned off Mars magnetic field. It may have been a cascade of events in the early inner solar system. Hypothetically, if Jupiter and Saturn formed in the inner solar system near the accretion of gas from which the Sun would ignite (which would create the Ort Cloud); with the inner rocky proto planets also forming, or having already formed before the Sun's ignition, the planet that is now the asteroid belt was ripped apart falling between Jupiter and Saturn's convergent orbits, propelled by the force of the Sun's ignition. Debris from the asteroid belt, that planet and possibly its moon(s) would then cascade throughout that accretion plane or disk, possibly Mar's moons with a large remnant fragment of that largest impact site on Mars. As Jupiter and Saturn's orbits slowly expanded. There may have been two orbital convergences at a minimum with the asteroid belt planet. There does exist a void or an area that is less dense in the asteroid belt, possibly the cutoff point which would form Saturn's rings and through which Saturn transited, Jupiter might have already drifted further out.

I'm confused. With my own eyes, I saw Quaid start the reactor. Shouldn't there be an atmosphere?

So you are saying that Mars still has at least some kind of molten core, and that the mantle plume still exists? I had always thought that Mars was dead internally having already lost most of its heat. One would expect a smaller planet to become cold faster than a bigger one. What evidence is there for a molten core? As far as I know there is no magnetic field like the one that is generated by our molten core. For comparison do Mercury and Venus have molten cores and/or magnetic fields?

Do you think that this one volcano was the cause of the loss of atmosphere?

Very interesting video, but what about Alba Mons??? The volcano is not as tall as Olympus Mons but in surface area it's larger.

Tsunami? On Mars? Perhaps you should do a collaboration with ingomar200. That would be awesome! It would be interesting just to see what kind of damage a massive Tsunami could do to the estimated geology of Mars, not to mention the fact the planet has a different amount ((?) Correct terminology?) of gravity. Still getting over the fact my house sits just a few miles away from the Des Plaines asteroid crater. Thank you again for that video.

I was hoping you would make a video about the July 11th earthquake swarm off of the coast of British Columbia.

Could you do a video about venus volcanoes

Is there any veracity to the correlation between the Tharsis volcanoes and the enormous craters near their antipodes? Is the correlation not causation? Why else might Mars have such volcanic activity that is not balances worldwide?

KZread premium users being forced to watch youtube premium ads...

That was great, thank you. If Mars had so much water, why no platonic plates?

Olympus Mons reminds me of teenagers … giant pimple and all 😂

i know this isn't a space channel, but is there a geological reason why mars does not have a magnetic shield? if it has a molten core still, is it stagnant or just rotating to slow to produce and electro-magnetic field? lastly how did men from mars and women from Venus get to earth if they hadn't developed a space program yet, is there a wormhole??? (for those who don't understand humor, the last question is a joke. maybe. it is. or is it.....

So, I’m guessing the craters on the side of the edifice (not the summit calderas) are impact craters?

I wonder what having that mass on the one spot does to the rotation of the planet itself? It must be like having a lead weight on a wheel.

Was earth like that with siberian traps before pangea broke because ( likely not certain) asteroid that hit Antarctica making the magnetic anomaly ? Before we had plate techtonics....

To be fair Olympus Mons does have an average slope of 5%, which is comparable to the big shield volcanoes in Hawaii. Although those are gently sloping, they are still very clearly mountains (unlike, say, the ice domes in Antarctica). In addition, Olympus Mons does have 6+ kilometer high cliffs at its base. The common statement that you would not know you were on a mountain if you were on Olympus Mons is not quite true.
