This past week there has been an earthquake swarm between Old Faithful and West Yellowstone. And living in the Park I knew absolutely nothing about this until today. There are always earthquakes here, most are never felt. I, for one, always wanted to at least feel a tremor but I'm still waiting for that moment. This summer, when laying in bed, I could have sworn that my bed shook but I chalked that incident up to being over tired.
As of 9:00 this morning there had been 1,033 earthquakes here since Sunday afternoon when the swarm began. People have felt them all over the Park and as far north as Gardiner. Earlier this week Judy heard one of these tremors - she heard her dishes rattle. Reading a news release I learned that scientists believe that this swarm is due to tectonics and not volcanic activity. Good to know.
There is a link on the right of this page that will show you where, when, how deep, etc. that these earthquakes are. Yellowstone is definately one fascinating place.
