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?
