CLINTONVILLE- The U.S. Geological Survey confirms it recorded a low-level, 1.5-magnitude earthquake at 12:15 Tuesday morning in Clintonville.

According to the USGS, the epicenter of the earthquake was on the north end of Clintonville, four miles beneath the earth's surface.

"We have heard the reports that people heard explosions or booms and they may be associated with other (earthquakes) but we don't know that for sure yet," said Paul Caruso of USGS to Newsradio 620 WTMJ.  "Right now we are trying to locate other (earthquakes) that may have occurred in that area."

Clintonville City Administrator Lisa Kuss told the community Thursday "the mystery is solved." She says the rumbling can be explained by a 1.5 magnitude earthquake that struck Tuesday and was confirmed by federal geologists Thursday.

She says representatives from the U.S. Geological Survey describe the cause as a swarm of several small earthquakes in a very short time.

While USGS geophysicist Paul Caruso tells The Associated Press that loud booming noises have been known to accompany earthquakes, he says he's skeptical that such a small earthquake would produce the loud booms that shook many residents awake.

A series of new reports of mysterious booms came into the WTMJ newsroom Thursday morning.

Authorities tell us of four of those reports coming in since 4:00 a.m. Thursday.

Many people have told authorities in Clintonville that they have experienced homes and household objects rattling as early as 9:30 a.m. Sunday, March 18 .

A Waukesha engineering company was expected to install monitors in Clintonville measure the vibrations underground.
