It’s been a relatively quiet morning in Clintonville, where shaking ground and large booms have kept folks awake this week. Police received a few calls overnight, but not nearly as many as the 30 from Wednesday, or 100-to-150 calls the previous days.
Residents gathered last night for a public meeting hosted by City Administrator Lisa Kuss. She said officials are “fairly certain,” after speaking with geologists, the rapid warm-up over the last week is a factor. Kuss said it’s possible the granite rock could be shifting, causing the explosion-type noises that first started Sunday night.
However, local man Chuck Sitzwohl said he heard the noise few weeks ago, and “every so often” for the past several years.

Resident John Schaefer said he was knocked out of his chair during a Wednesday morning boom.
Seismologists have also investigated, finding no evidence of earthquake activity.
Meanwhile, the Waupaca County community hired a Waukesha engineering firm, Ruekert & Mielke, to set up sensors and look for an epicenter. Kuss said if the firm is successful, city officials will determine their next step. But she said it’s possible they’ll never have an answer.
