- 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.
Four seismometers have been installed and so far confirmed a .1 magnitude earthquake March 30.
City administrator Lisa Kuss (kus) said Wednesday police have only received a handful of calls recently.
U.S. Geological Survey Geophysicist John Bellini says he's still comparing their data with resident reports but haven't found anything substantial.
He suspects the events are a swarm of small earthquakes, which is not unusual across the nation.
