USGS: Micro-quake near city bothered by booms
MILWAUKEE | Federal geologists confirmed Thursday that a minor earthquake occurred this week near the eastern Wisconsin city where researchers have been investigating a series of unexplained booming sounds.
The U.S. Geological Survey said the 1.5-magnitude earthquake struck Tuesday just after midnight in Clintonville, a town of about 4,600 people about 40 miles west of Green Bay.
Geophysicist Paul Caruso said that loud booming noises have been known to accompany earthquakes. He said the mysterious sounds that town officials have been investigating could be linked to the quake.
“To be honest, I’m skeptical that there’d be a sound report associated with such a small earthquake, but it’s possible,” Mr. Caruso said.
