When I read this article, it brought to mind the mud volcano in Indonesia. It just seems things are a bit close to the wire. What standards would they use for safety? Should some standards organization set an exclusion zone? Would the fear of the populace allow a terrorist to find comfort? And terrorist he would be, since the only way to 'fight' this would be to blow up a pipe near a town, and kill people.
They should definitely work with the people to allay fear. Monitoring stations, emergency drills, etc.
