More tunnels being demolished by white hats. This time over in the Eastern Area of the U.S.

There were 4 earthquakes all about the same depth and all small. They were in areas that do not normally get quakes. They were all close to the Smoky Mountains area. I have no doubt there are many tunnels in the Smoky Mountains.
