When there were reports of similar booms or suspected earthquakes in Franklin, a geologist interviewed on TV said it was likely a "karst collapse" - an underground collapse of the room of a cave chamber.

We just heard the same thing in Columbus Indiana at 9:30pm. I was in the shower, but I heard the whole house shake like someone in it knocked over a table. My family said it came from outside. No tree branches fell. We live about 10 -15 miles from Camp Atterbury, a very active military hold/training site.
