The USGS has changed their earthquake map. Follow the directions and you will figure it out. The reason I am posting this is there are things going on in Yellowstone. This new map shows 2 maybe 3 swarms going on there right now. I have suspected this for awhile as the seismographs have been showing magma movement for about a month or more, and they have added 6 new seimos to the park about 2 weeks ago. Something is going on up there.
