Except that the tidal effect of Mars is infinitesimal, and falls WELL below the variational noise floor of the Moon, Sun, and other bodies that actually do have significant tidal effects.
No, Mars has exactly nothing to do with it, hence why it is being ignored.
I wonder what the correlation between volcano, supervolcanoes (calderas) and Mars would be.
Another poster whom I have no reason to doubt, has said that the gravitational influence of Mars is below the limits of pull exerted by the moon.
But, if the close approach of Mars correlates to some volcanic activity on Earth, would that mean there is more to it than we understand?
I have been following the events at Yellowstone rather closely for two years.
Someone mentioned the rise of the dome. Not mentioned on this thread is the rise in temp. of the water, the rise in sulphur gases, increase of earthquake activity.
Now, let me qoute you a line from an older thread on Yellowstone.
Preliminary study indicates that quakes that large are likely to occur every 100 or so years. And it's been 70,000 years since the last major volcanic eruption at Yellowstone.
So, it would seem that the eruptions have corresponded to Mars approach approx. 70,000 years ago, and seem to be doing so now. If the grav. influence is not the cause, wherein lies the answer?
Maybe MARS being the closest it's been in almost the same exact geologic time since the last eruption.
Nah........must be a coincidence.
I can't resist this one.
1. Close approaches of Mars occur every 15-17 years. This approach is only a fraction closer than many other "favorable" approaches -- for example, this year Mars will span 25.11 arc seconds as seen from Earth, while in 1971 the apparent diameter was 24.9 arc seconds.
2. The Mars approach you are referring to occurred 59,619 years ago, while the most recent Yellowstone eruption was about 75,000 years ago. Which seems rather a long lag.
3. The variations in gravitational pull produced on the Earth by Mars are a completely trivial fraction of those exerted by the Moon.
4. Why do you suppose that the gravity of Mars would pull harder on the Yellowstone caldera than on anything else?
What do I think?? I'm thinking eastern Colorado may not be far enough away.
Umm... Because temporal correlation is not an indicator of causation? Mars isn't magical, and its gravitational pull is insignificant. Sparse priors lead to irrational conclusions.
For example, just because 1990 and 2000 were great years for Bordeaux wines does not mean that 2010 will be a great year for Bordeaux. Lacking causitive association to years that end in zero, it is safe to assume that the correlation is coincidence.
Mars approaches closest to the Earth approx. every 69,000 years. Is that correct.?
Approx 69,000 years ago, the caldera blew. Is that correct?
Your figure of 59,619 years ago , how correct would that be?
What causes volcanoes, caldera's to expand and eventually blow? We know the mechanics of the buildup of pressure, etc. What causes the original effects that leadup to this? Movement of Magma? What causes that?
Do you know if anyone has done a correlation between Mars and Volcano Eruption? Don't assume that gravity is necessarily the 'cause'.
Those that tell me it can't since the gravity effect is nil, I ask to remember there is much we do not understand, about other planets, and Earth. First to tell me if the core of the Earth is Solid or Liquid, and be correct, wins.

What makes you think it is necessarily Gravity, as we know it? Could it be something else? Is is the net change in effect of solar radiation? Does Mars exhort some effect we don't yet understand?
It is best not to ignore the God of War.
NOW THAT is outside the box thinking. I am impressed!
Thank you. That was my intent.
Mars approaches closest to the Earth approx. every 69,000 years. Is that correct.?
No. Mars approaches closest to the Earth every 15-17 years. This distance varies a little bit each time, but not much.
Approx 69,000 years ago, the caldera blew. Is that correct?
The Yellowstone National Park site has the most recent explosion at 70,000 years ago. How precise the number is isn't clear.
Your figure of 59,619 years ago , how correct would that be?
Exactly correct, to the year.
What causes volcanoes, caldera's to expand and eventually blow? We know the mechanics of the buildup of pressure, etc. What causes the original effects that leadup to this? Movement of Magma? What causes that?
I don't know.

I can't see why anyone would, but if you want to find out I recommend doing a web search.

That's called changing the subject to hide your own lack of understanding. Not a good way to learn.
Along with others, I stated that the gravitational effects of Mars are trivial compared to those of the Moon. This is not opinion, but fact. Anyone who is interested can confirm this. If for some reason you insist on ascribing remarkable powers to Mars that science has overlooked, *you* are obliged to come up with some sort of evidence supporting your position.
What it looks like is that you have come up with an idea based on nothing but the similarity of two numbers, and are now carefully ignoring all evidence to the contrary.
I'll be happy to continue this conversation, but first you have to go find the relative gravitational effects of Mars and the Moon and post a link here, by way of showing that you care about objective reality.
