Another East TN earthquake in the early morning hours today:

I have yet to feel any of these but they have been fairly frequent over the past few weeks.

I haven't felt any either.  Of course, most seem to be occurring in the wee hours of the morning when I'm dreaming of  ::snow::

A 2.8 magnitude earthquake happened tonight around 8:30 pm near Shelbyville.

We are definitely seeing an uptick in seismic activity over this way...

That's an unusual spot- quite honestly not all that far from me. Don't recall noticing anything at that time, but it was a sub-3 after all.

Reportedly felt around Shelbyville and Tullahoma.

It's a bit worrisome, because little is known about the faults that riddle TN (outside the New Madrid seismic zone).  East TN is covered with them, which is what makes up the ridge/valley area east of the Plateau.  Multiple rifts and cracks are left over from the time when the Appalachians were uplifted.  What's causing these faults to suddenly rumble to life?  And does the  magnetic pole shifting around somehow related?

We may not like the answer to our question as to what's going on.

I live in Christiana and we didnít feel it.   Very odd

I haven't felt any of the other East TN quakes since the first one that sparked the creation of this thread. I spent 3 weeks in Middle TN for the holiday though.

If this uptick in seismic activity is a sign of things to come, I hope our infrastructure is prepared. TVA says so, but who knows about the older, non-governmental buildings. I did a little of my own research last month and found that a quake in excess of 5.0 is almost impossible in East TN. I hope that is true, because anything over 5.0 would do damage on our civil infrastructure over here.
