Yeah, there are occasionally tremors in the mountains of East TN.

The fault that everyone is really concerned about, though, is the New Madrid Fault, which runs through the extreme northwest corner of West TN, around Reelfoot Lake.  That could cause a serious earthquake for much of the midsouth in the future.

In addition to weather, I used to have an interest in seismology, as well.  :)

Yeah, that USGS site is pretty interesting.  I guess having an interest in this geological activity kind of goes hand in hand with the weather.  The New Madrid fault line is the biggest reason why we opted for Earthquake insurance too.... :shock:

Yeah, that's what made the "land between the lakes" area if I'm not mistaken.  A big one back in the day made the Mississippi River flow backwards or something.  I remember there was one about 3 or 4 years ago that woke us up.  Pretty freaky if you've never felt one.

The East Tennessee area is full of faults due to the fact that it was once a plate boundary.  Faults remained in that area and build up strain.  I don't know if it has enough power to do major damage, but I know that it's on the same general system as the fault northwest of New York City, which will produce a severe quake in that region in the next 100 years.  The New Madrid fault is the biggest concern, but a major earthquake won't likely happen there for at least a century.  Maybe a 6.0 or 6.1 (which is not so bad, but considering that no building here has been retrofitted) is possible in the next fifty years, but even that's a bit of a stretch.

Land Between the Lakes are just the Tennessee and Cumberland Rivers dammed up to create Kentucky Lake and Lake Barkley.  This was created by TVA, not an earthquake.   :wink:

Three powerful earthquakes in the winter of 1811 and 1812 did create Reelfoot Lake, however.  The land sunk in the area and flooded.

Reelfoot Lake in West Tn was formed by a HUGE earthquake back in the day.  It was formed when the Mississippi flowed backwards.

FYI,

Here is an interactive map of recent earthquakes recorded in the Central and Eastern U.S.: http://folkworm.ceri.memphis.edu/recenteqs/.

Cool!!  That's a little easier than going to the USGS site all the time.  It's amazing how many 'little quakes' there are DAILY in this country.
