Update:

From NBC2 News:

The strange disturbance sounds like distant thunder, fireworks or someone slamming a heavy door. At first, many people were amused. But after a third restless night Tuesday into Wednesday, exasperation is mounting. And some folks are considering leaving town until investigators determine the source of the racket.

“My husband thought it was cool, but I don’t think so. This is not a joke,” said Jolene Van Beek, who awoke early Sunday to a loud boom that shook her house. “I don’t know what it is, but I just want it to stop.”

The booming in Clintonville continued Monday and Tuesday nights and into Wednesday morning, eventually prompting Van Beek to take her three sons to her father’s home, 10 minutes away, so they could get some uninterrupted sleep.

There have been no reports of injury, despite some residents saying they could feel the ground roll beneath their feet.

From the LaCrosse Tribune:

Mysterious underground booms resumed early today in the eastern Wisconsin community of Clintonville after a quiet night.

The noise awakened some residents Sunday and Monday night. After checking numerous theories about what may have caused the noise, authorities are still at a loss to explain the origin.

Police dispatcher Tabitha Schoen says it was a quiet night in Clintonville until shortly after 5 a.m. when about 20 calls came in from residents who experienced the booms. They’ve been described as rumbles of thunder, sonic booms or fireworks and have rattled houses.

A meeting about the mysterious noise is scheduled Wednesday night at the high school in Clintonville.
