First of all yellowstone is a giant volcano and this is important because people need to understand that volcanos cause earthquakes. EARTHQUAKES DO
NOT CAUSE VOLCANIC ERUPTIONS. EVER.
Yellowstone will erupt when enough gas in the magma has been built up and put under enough pressure with no where for it to go. The biggest earthquake
ever recorded could happen in yellowstone and it would not cause the volcano to erupt.
Think of it like this. Take a tube of toothpaste and puncture it with the tip of a pencil. What happens? The toothpaste will slowly ooze out..very
Now put the tube under pressure to the point of almost bursting and puncture it again..big explosion of toothpaste. The point is that yellowstone is
no where near the point of having enough gas to erupt. If it was you would see many other signs beforehand, massive increase in temperature, release
of gases more prevelant than what is there now, a serious serious uplift in the geography around the caldera, none of which is happening.
Yellowstone has hundreds and probably thousands of years before it erupts again so don't let posts like this scare you into thinking it's the end of
the world cause it's not.
I think you ought to read a little more on the subject and I am not one that thinks an eruption is necessarily likely near term. However if you read
the YVO's own status and risk study of 2007 you will find you have misstated several items. First EQs are thought to play a key role in eruptions both
magmatic and hydrothermic eruptions at Yellowstone. The movement of magma will cause many small EQs however the movement of magma can be caused by
EQs. If you do a little reading I bet you will find out what the size depth and location of EQs in the system area hints to the YVO about what is
Also while the current thinking is that the activity will really ramp up before any magmatic eruption the scientist are the FIRST to admit that they
do not know what a ramp up would look like or how long it would show itself. The fact is that the system is very overdue for an eruption
statistically. While this can't be said about a major caldera forming event because there are not enough data points to make any reasonable
determination of the occurance rates for these huge events. But there is no doubt that the system is due for both balsaltic lava flows and the
explosive events that people are afraid of, even if the explosive event would likey be smaller than the supervalcano events we see talked about. The
other fact is that there has been unusual activity recently at Yellowstone (recent being a 15 year span). There is valid evidence that the Magma
chamber has been expanding and at the fastest rate that we have recorded. The rub is we have not been watching for any kind of meaningful period.
There have been several swarms at shallow depth, that the YVO's own documents indicate would be a likely precursor of an event.
So while many posting like Puterman and westcoast and TA are "recreational geologists" we have educated ourselves about this and other systems. While
I would never predict an eruption in the near term I think there is nothing wrong with threads like this discussing the status of the system. I also
have serious doubts as to how forthcoming the government would be with troubling data. Lowenstern himself has said that when answering questions and
giving information consideration is given to providing the answer that produces the fewest questions and is likely to satisfy the person asking the
question. That does not lead me to believe he is sharing all of the data or his concerns with us. BTW I don't have a huge problem with some of that. I
do have a huge problem with not having access to the current data obtained from InSAR and the imaging of the changes in the magma chamber.
To wrap this up I don't see the regulars on this topic fear mongering and I think it is a positive that people are learning this stuff themselves and
will have a chance to make the PTB be straight with us if or when the activities really pick up. I suppose that you think the government would be
conservative with evacuation orders for say 25 million people if Yellowstone really threatened. The economic impact would be staggering and I don't
trust them to be honest.
