The eastern Wisconsin community where intermittent booming has kept some residents up at night will hire an engineering firm to explore the cause of the racket.
Clintonville administrator Lisa Kuss said Thursday the engineering firm will install four ground seismology monitors around the city to determine whether there's an epicenter to the noises that seem to be underground. Ruekert & Mielke, of Waukesha, will analyze the data once engineers get a good reading. Kuss says it's not known how long that will take. She says the city will spend up to $7,000 on the effort.
Kuss says a handful of calls early Thursday to police reported some minor booms, unlike previous nights when dozens of calls were placed to dispatchers about explosion-like sounds that roused residents from their sleep.
