    Can a person force a Volcano to go off ?
    If so how would they go about doing so.

    This is just a question ?

    I assume that by "a person" you mean "can people start a volcanic explosion"? I would say: probably. Given a volcano that was showing signs of an imminent eruption, a well placed thermonuclear bomb might start it off. Also, a deep-drilling rig, drilling straight down next to the lava dome inside the crater of a volcano -- although I don't know where you would find the crew to man it. Both these methods assume a volcano that is showing signs of eruption and not an extinct volcano.

    I believe that in Iceland, they drill down several kilometers to the magma and use it to heat water that eventually supplies almost all of the country's electrical/heating needs.

    That information about Iceland astounds me.
    Drilling a hole of that depth in a lake bed, so that a large body of water came into contact with those deep, hot rocks, might give an eruption a start. The magma would still have to be at sufficient pressure to force it out onto the surface though. It's not like a rabid dog, always trying to get out of the yard!

    Some researchers think that an earthquake (sometimes big) may be caused by human jobs, such as water dams, toxic waste injection, coal and gas extraction.

    The "water dams" cause rings true. I read that the varying water level of the Salton Sea may have some effect on earthquakes in the lower San Andreas Fault region -- I believe it was research done at the University of California.

    I don't think there's any doubt about. Geologist made the link back in the 1930's when our big damn projects (e.g., Hover, Cooley) produced many small tremors.

    Most geothermal drilling doesn't reach magma, I know of only two cases where it did in Iceland and in both cases the drill was withdrawn and the Magma immediately sealed the bottom of the hole. At least one of these wells are being used as test wells to deliver super heated dry steam (750 F) for new methods of power generation. Most geothermal however is shallower or even when deeper doesn't reach the magma. These wells deliver wet steam at about 570 F. Wet steam has higher water content than dry steam and is much less efficient at producing power. All current geothermal power stations use wet steam.

    As poor mystic indicated just because the magma is hit would not result in an eruption. In one case when the drill was withdrawn by 10 meters the magma only filled the bottom of the bore hole with 9 meters of rock. This "plug" prevented further filling of the borehole.

    That confirms the relationship between moon phases and seismic activity. Besides the moon gravity may have a direct effect on magma.

    Yes. It's not just the oceans that are affected by the Moon. The Earth's crust is also moved up and down by the Moon's gravitational pull -- I forget the exact amount of movement but I think it is less than a meter.

    ETA: I think the value is 25 cm for a high tide.

    The grounds tides are about 12 inches in height and follow closely the Moon where water tides are delayed by several hours.

    This doesn't confirm anything unless you can point at scientific data that shows the correlation between the two. What you have is a hypothesis. Now you have to prove it with data and predictions. It is not that simple that earthquakes and the position of the Moon go hand in hand. Tides are greatest when the moon is new or full. This is when the Sun and Moon are pulling on the Earth on the same axis. Tides are less when the Moon is at one of the quarter positions (half lit). This is when the pull of the Sun and Moon are at perpendicular axis.

    The Japan earthquake on March 11, 2011 happened when the Moon was in the first quarter.

    The weight of water and ice can also cause changes to the local crust. Ice sheets put tremendous pressure on the crust which can alter the stresses in an area. In the case of the Salton Sea and large dams the weight of the water is even greater, 8.34 lbs (3.78Kg) per Gallon or 62.42 lbs (28.31 Kg) per cubic foot. That much weight has a bigger impact on the local crust than the Moon. After the Hoover dam was built the weight of the water behind it (24 billion tons) caused the surrounding area to subside by 5.5 feet (1.7 meters).

    The reason for the question is that it has been suggested.
    That the Volcano in japan may had been caused.
    Which may had caused that lage tidle wave to hit japan.

    Reason for that .Is because all the fighting in the middle east. While were dealing with japan.
    The fighting can take a change without noticed because of japans problem.
    This was the reason for the question.
    Could someone cause a Volcano to go off. Which caused more earthquakes which caused the Tidel Wave in Japan......To thro us off track with the War over seas.

    Maybe, but nobody can prove this. It is a fact that Japan has ever been an high seismic area...http://www.pdc.org/iweb/earthquake_history.jsp

    You need to start listening to people that are not crazy or stop believing what you see in James Bond films. SPECTRE did not really have a base in the Shinmoedake volcano.

    If you are truly interested in geology then take a look at the USGS site at http://earthquake.usgs.gov/earthquakes/recenteqsww/ . This earthquake data is gathered from all over the world and clearly shows that earthquakes are happening all the time, however we don't always feel them or they happen in remote places. This is a completely natural occurrence.

    The earthquake that happened in Japan was a NATURAL disaster. Suggesting a man made source is absurd since an explosion on that scale would also be registered on the seismograph. The stations around the world that provide this data allow scientists to accurately determine the location, intensity and depth of the quake.

    The volcano that erupted in March in southern Japan was 2 days after the quake. The Shinmoedake volcano had been active for months before the quake, and had eruptions as well in both 2008, and 2009.

    Who suggested this? Where did you read this?
