Clintonville City Administrator Lisa Kuss reportedly met with civil engineers and geologists on Tuesday morning. Officials are checking the water system to see if there are any problems. Officials are also checking gas lines, sewers and water pressure systems, but they have yet to find a source of the loud noises.
Kuss believes the noises are coming from underground, reported the AP, and the next plan is to check well pumps to make sure they are operating properly.

The ground is shaking in an unusual way, said Thurber.
