Areas of seismic activity at least in the U.S.?
I realize that "active" could be a subjective term when This seismic activity, and that Illinois had its strongest earthquake in 40 years two weeks ago, with considerable activity, both in the area shortly time, but I thought in the last 50-100 years, which was the least active areas of seismic activity in the U.S.? I understand that this service United States Geological Survey mapping almost never stop showing Aleutian seismic activity: In http://earthquake.usgs.gov/eqcenter/recenteqsus/ staff side I thought I was going through the 5.2 was pretty cool. I had my morning coffee when he arrived, and I woke up … shake of land, no coffee. 🙂
