Louisville residents searching for the source of an unexplained ground-shaking boom can scratch another theory off the list.
A Loudon County resident speculated on Thursday that the noise could have come from maintenance on an underground pipeline (see previous story below). The Plantation Pipe Line Company operates a large liquid refined petroleum pipeline that runs from Knoxville to Macon, Georgia. The pipeline is co-owned and operated by Kinder Morgan.
Emily Mir with Kinder Morgan's media relations department contacted 10News on Friday morning and indicated there were no recent operations that would have created the noise. Furthermore, the pipeline in question is located around 10 miles from the Lashbrooke subdivision.
"Last Monday, about a week and a half ago, it was around 3 a.m. and it was, 'Pow!' All the sudden we heard a loud explosion. It sounded like it came from inside our house. It shook the walls. It shook the floor. It shook the ceiling," said Wombold.
Wombold said he ran upstairs to check on his parents and ran into his father who was already headed downstairs.
"We thought maybe a gas line had exploded and maybe our house was going to blow up. We thought it was really serious," said Wombold.
"It was like lightning struck directly beside the house," said neighbor Dwayne Jones. "I jumped out of bed and ran outside. Then I saw a clear sky full of stars and knew it wasn't lightning. The ground was still shaking for a little bit. It was like a big sonic boom. Just the whole house shakes. I never heard anything like it."

The fact that there are now 3 states, within days of each other, all having a loud boom (and houses shaking) is quite strange. But the question is, what is the common denominator?
Earthquake "booms" have been reported for a long time, and they tend to occur more in the Northeastern US and along the East Coast. there have been many reports of "booms" that cannot be explained by man-made sources. No one knows for sure, but scientists speculate that these "booms" are probably small shallow earthquakes that are too small to be recorded, but large enough to be felt by people nearby.
There are accounts of "artillery"-like sounds that were said to have occurred before or during the New Madrid earthquakes of 1811-1812.
There is "something new and interesting going on in the universe," said Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md.
ARCADE's mission was to search the sky for faint signs of heat from the first generation of stars, but instead they heard a roar from the distant reaches of the universe.
