Wondering about line of quakes across US

s1229.photobucket.com...

What do you think of the line of quakes from Tennessee to Oklahoma to New Mexico?

This is probably not worth mentioning...I just was wondering if that "line" is fault?

There are a couple of quakes that I think are on the New Madriad Fault.. The others I am not sure about - by that I mean I don't know if it is rare to see them there. We had a quake here in Indiana a few weeks ago that was considered very rare and those that study quakes were not sure what caused it. We have an ATS thread titled Earthquakes 2011 - would give the link but for some reason all my features on ATS are not working. The experts at this site are very informative. Thank you for bring the line to our attention.
