I recall a string of quakes a few years ago.

The U.S. Geological Survey said that at first glance, there was no need for alarm, adding in a statement that there was "no indication of additional geologic activity other than continuing seismicity" after the main quake.

I can't possible imagine what they would say if there was cause for alarm: "Please exit these 17 states as quickly as possible..."
