Follow Up of the Day: Clintonville Explosions Explained

Has the mystery of Clintonville's bizarre booming sounds been solved? If scientists are to be believed, the cause of the noisy phenomenon is a "swarm of microquakes."

"The mystery is solved. We have experienced an earthquake here in Clintonville," City Administrator Lisa Kuss told residents at a city meeting last night. The USGS backed up its "claim" with "evidence" showing that a 1.5 magnitude earthquake struck the central Wisconsin city around noon on Tuesday.

Residents, who began hearing strange rumbles this past Sunday, challenged the city's explanation, saying quakes had previously been ruled out. Kuss admits that it was "by fluke" that the USGS's traveling portable arrays happened to be in the area when the tremors occurred.

For now, this is the best answer the city has to give, though officials acknowledge they aren't sure it's the only answer, so Graboids are very much still on the table.

The city of Clintonville, Wisconsin, has been unable to explain a series of loud noises that started earlier this week and have occurred multiple times since.

The sounds have been described by locals as resembling "thunder, fireworks or someone slamming a heavy door."

Officials have set up recording equipment in an effort to find the source of the "booming sounds" that have reportedly roused residents from their sleep. That effort has been unsuccessful thus far, as has every attempt to explain away the mystery with manmade causes.

City administrator Lisa Kuss said they have so far ruled out water, sewer, gas, landfill, military, and mining-related origins, as well as known geological phenomena.

vibration-detection devices, set to be installed by Friday, will be used to determine the clamor's episcenter.

A city meeting has been called for 6 PM this evening. A Q&A session will be held, but Kuss has already acknowledged that there is no new information to disseminate at this time.
