My BFF's DH was the earthquake specialist for the UGS. He now works in Virginia at the USGS. Yellowstone and Utah have seismic activity virtually daily. My DH is a geologist and he says that any seismic activity is considered an earthquake. If they are small the are considered micro-quakes. Earthquakes happen along fault lines. They are everywhere in the US. Salt Lake City is sitting on a big one. One day in the future we will have a quake measuring a minimum of 7.0. If you look at the geologic records you will see that SLC is overdue for the "big one". That is why they are getting all the structures up to earthquake code around here. California also has lots of faults. I'm sure I could give you a longer lesson but I'm sure your eyes have glazed over by now :wink:

For national this is the USGS site. Shows all the earthquakes recently:
