CLINTONVILLE, Wis. (AP) -- The reports of booming in Clintonville have quieted down.
Residents started reporting the sounds and shaking March 18 and experts detected a 1.5-magnitude earthquake about two days later. The reports started to die down until another big boom over a week later. There have been a few reports since then.
