Well, lets all pray nothing major happens. They are saying that there is a low potential for volcanic activity though. "Similar earthquake swarms have occurred in the past in Yellowstone without triggering steam explosions or volcanic activity. Nevertheless, there is some potential for hydrothermal explosions and earthquakes may continue or increase in magnitude. There is a much lower potential for related volcanic activity." Lets hope they are right. This update should be a relief to some of you out there worrying about the caldera popping off, although the potential for the quakes to increase in magnitude is a little nerve racking.
