Hello, Andrew, I studied the discussion from last April. That was started by you also. The mud volcano issue came up there as well (in a reference). I did not see a compelling argument there against the possibility of triggering eruptions. Why the interest in mud volcanoes? They appear to be small events, and I can't see their benefit. You may recall that I have an interest in triggering volcanoes, especially marine ones. I have thought about the prospects of triggering an eruption, and maybe I have an idea or two. I noticed a report of a study showing an increase in volcanic activity following rain. _http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6VCS-4WGK6N6-1&_u ser=10&_coverDate=07%2F20%2F2009&_rdoc=1&_fmt=high&_orig=search&_sort=d&_doc anchor=&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=7291 5643ef239c7ad2001d2fce18411a_ (http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6VCS-4WGK6N6-1&_user=10&_coverDate=07/20/2009&_rdoc=1&_fmt=high &_orig=search&_sort=d&_docanchor=&view=c&_acct=C000050221&_version=1&_urlVer sion=0&_userid=10&md5=72915643ef239c7ad2001d2fce18411a) It is also well established that water can cause earth shifts by lubricating fault lines or otherwise, thus causing earthquakes. And, earthquakes can trigger eruptions. Of course, we are talking about eruptions that would have happened anyway, but at a future time. Soo-- I propose that one consider the possibility of igniting a volcano by injecting a lubricant, possibly water, into a suitable fault plane. Some volcanoes are extremely dangerous, the yellowstone caldera for example. I think this one would be easy to trigger--it would promptly bring global warming to an end, but much of earth life would end at the same time. It could be hard to find the right situation. My view is that a volcano has two possible benefits: (1) injection of sulfate /SO2 aerosol into the stratosphere and (2) release of basic magma or ash into the biosphere (either air or water) so as to absorb CO2. Either effect could be favored by choice of volcano. I don't have a great knowledge of geology. But, I think this line of thought should be pursued.

Previous discussion on this list suggested that volcanic eruptions can't be artificially triggered. This story suggests otherwise: _http://en.wikipedia.org/wiki/Sidoarjo_mud_flow_ (http://en.wikipedia.org/wiki/Sidoarjo_mud_flow) I'm interested to know if this can be applied to lava volcanoes.
