Yellowstone National Park has been experiencing earthquake swarms for about a week. Today an extended period of harmonic tremors began. I'll add a couple of links to the Yellowstone Volcanoe Observatory site. For those unaware, northwestern Wyoming, specifically Yellowstone National Park, is a super-volcanoe. There have been several TV specials about it. The last link explains what harmonic tremors are, and what they normally precede.
