is it possible to slowly release volcanic pressure slowly, manually?  B)  :(!  :0  O8) (poof!) you can evacuate the place with no rush cause you know you will cause the eruption, if it don't blow first. possabilty of less deaths, or set deep charges to increse plate shifting after a mager earthquake every few years to triger small quakes insted of wating for the big one? xx(

How would you accomplish this?  The technical problems are almost prohibitive.  And who's to blame if you make it worse instead of better?

Isn't that the purpose of volcanic plugs?

if the astroid that they plan to mine in earthes orbit can cause unwanted pulls on earths tides, and eruptions, like the moon, but they are planning to do so any way with in the next two years, why? i don't know. but if i lived in a place like yellow stone, right over a supper volcano, i would want to 1-move every one away from it befor the time of eruption (thoe it would wipe out every thing in the middle amercas thus putting an end to the population problum in a bad way...)  2-if we can run pipe lines in to the earth casing a few places to erupt first, in small spots like letting out the gas, and magma out some where else close to the supper volcano maby it won't go pompei on our buts. lance it like a boil. Ewww yes. Ouch! yes, but get more holes less pain! and as far as the fault lines, we know where they are, and if you drill i line of holes, in a brick dosent it break easer? relese of preshure will happen no stopping it from going boom, but the hard part is the simple reality of people that live there won't leave if there might be an eruption, but more will leave if there will be one. big buisnesses won't leave if money is to be made, but if there buildings are more likely to survive small shifts.     besides i only asked the big guys and ppl like you if it is posable? ty  what do you think?

who do we blame lol? no one. we might just have time to save lives, and let mother earth spank us! lol yes i think that is what they are for.

Bass look up the size of the volcano under yellow stone. if i had to save my daughter  from going through a newclear winter, and shrink a masive seunomi, that could wipe out Hawaii. i would let people try this. Would you?

Keep in mind that there are several types of volcanoes.

The Hawaiian volcanoes tend to just ooze runny stuff almost continuously.  Perhaps that would be a goal as they may be some of the most predictable volcanoes, but it may not in fact be possible to just artificially create such an occurrence.

Other volcanoes go through phases.  In the Cascades, there seem to be long periods of "Cone Building", followed by a few brief explosive events. 

Anyway, not all volcanic eruptions are equally destructive. 

To some extent, volcanic eruptions can be predicted by observing earthquakes and bulging, and people can be evacuated, if they should choose to leave.  Precise timing and magnitude of the eruption may not be predicted, and many Washington residents got irritated with the government for an extended evacuation period prior to the Mt. St. Helens eruption.

One option might be doing aggressive geothermal energy recovery, with the goal of cooling the earth as far down as one can get.  But, I find it doubtful that one could really make that big of a difference.  Perhaps it would only briefly postpone the inevitable, which could make an eruption even more destructive.

One could try to drill out a new vent hole, or an existing vent hole.  Geothermal temperatures would become problematic for drilling long before one would encounter molten rock.  One might have to clear the last bit with an explosion, perhaps a small nuke.  But, keep in mind that with volcanoes, what goes down will come back up, so fallout could be a problem.

If the predicted rate of explosive eruptions is once every thousand, or once every million years, then one might end up spending a lot of time and money triggering a lot of small eruptions (once a decade?) to prevent a very rare event.  And, consider the number of "active" volcanoes in a mountain chain like the Cascades.

Anyway, the risk, of course, would be that you might not trigger a small eruption, but rather one might trigger a big eruption (just what one was trying to prevent).  Or, in a worst case, triggering a super-eruption.  And the use of large explosives might make this risk even greater.

If many volcanoes go through phases of:

Small Cone Building Eruption
Small Cone Building Eruption
Small Cone Building Eruption (Cone Complete)
Major Explosive Eruption
Small Cone Building Eruption
Small Cone Building Eruption
Small Cone Building Eruption (Cone Complete)
Major Explosive Eruption

Then, perhaps one might try to prevent the completion of the cone.

For example, one could start a program of "send your local neighborhood volcano cone to Florida.  And, thus aggressively remove the cones, and prevent the completion of the cone, in hopes of preventing the major eruption.

The risk, of course, is that many of the super volcanoes occur in the absence of cones.  So, removing the cone might in fact make it worse.

Mommylady28- I have studied Yellowstone extensively.  We simply don't have the technology to relieve the pressure on a volcanic system that size.  Drilling holes in would be like pricking an elephant with a very small pin.

Part of the reason that the silicic volcanoes can be so explosive is their high viscosity- they don't erupt flowing lava.  Because the molten rock is so thick and gooey (a new geological term), it sits underground accumulating volatile gases that eventually cause the "explosive" bang.  So even if you could drill a hole into the magma (molten rock), it wouldn't "flow" very far up the pipe before stopping it up. 
I agree that large explosive volcanoes are a hazard.  Luckily, they explode infrequently.
Our efforts might be best used to devise methods to cope with the aftermath, rather than try to stop the eruption.

A very interesting question indeed, I personally had no idea there was a project to mine an asteroid.  As to the effects on earth, I mean we have so many radical theorists out there, (including me) that anything can be possible.

Also with Yellowstone and Montana in general...  I have an aunt that lives in "West Yellowstone" and I have visited more than once.  One of the problems is the funds of the state, true Yellowstone is a Super Volcano and posses its risks for all of us.  Idk about you, but if it were going to blow off I would rather be at ground zero than where i'm at two states over.  Back to the funding issue, the state gets most of its civilian cash flow from three months, summer.  The rest of the season everything closes down and you'll be lucky to find a gas station with people in them.  You would have to drive hours to reach a decent sized town to restock, it is quite the remote scenery to be sure.

It is "possible" to make money off the volcano in thermal energy and such, but the biggest problem is just as you stated, "Who would take the blame?"  Not only would you have to go through years of political games and local civil laws, but just by drilling a few holes you could cause a preemptive eruption.

As for the pull of the asteroid on our earth, just by us creating dams for rivers we've tilted the earth's access slightly.  It's the butterfly effect, every action we do have unforeseeable consequences.  An interesting and scary concept is how our world is becoming more and more socialistic.  I believe not a volcano, but things like this new health care law that is going to be past and what it is going to do to our nation.  It is going to be introduced as a tax and so we now have to pay 50% of our hard earnings into taxes to provide health care.  This is for people that need it of course and also for people that just want to take advantage of all the money we earn by just not working.  This bill will also make people not want to become doctors, read it and tell me if you would want to be a doctor once this bill passes.  Read H. G. Well's "The Shape of Things to Come" It sounds good, but the biggest problem in a society is humanity, personal gain.

Bah, I've gotten off topic. 

Anyways, I believe it's not about the technology, but about funds and how our leaders use those funds...
Yeah, I'm not a fan of socialism as you might see xD

While drilling could potentially create a weak spot, we have difficulties drilling down to a depth where rock turns from solid to liquid.  And, if lava did start flowing up a well shaft, it would likely cool and plug the shaft quite quickly.

Icelanders have been effective in drilling for geothermal energy in an area that is volcanically active.

At the same time, extracting heat from a geothermal well would create minimal cooling of a "hot spot".  Consider all the boiling water in Yellowstone, with little impact on cooling the caldera.

Nah,  the amount of energy in molten rock is orders of magnitude greater than contained in the sorts of shales which can be "fracked" for hydrocarbons.

no chance the unfrakked volatiles will migrate to the volcano upon eruption rumblings?

they might do, but it would make no measureable difference
