CLINTONVILLE - The booms have returned in Clintonville, reportedly louder and longer than before.
"Between the times of 10:35 and 10:50 p.m., we received 60 phone calls from residents indicating that they were again hearing very loud, booming, rumbling-type noises," said Clintonville City Administrator Lisa Kuss to Newsradio 620 WTMJ's Nick Iannelli.
"Some were indicating that it was even louder than it was last week."
Last week, Kuss announced that geologists had discovered earthquakes of as high as 1.5 on the Richter scale in an area not known for them.
According to Kuss, these may have been more powerful, and extended for a longer period of time.
"Someone indicated that it seemed worse than last week. It also appeared that the rumbling duration lasted longer," said Kuss, who explained that the quakes of recent weeks had subsided over the weekend.
"It seemed like it was a little bit different in duration. Clearly, the intensity is back, whereas Friday, Saturday, Sunday and Monday, there (were) no events that generated that volume of calls."
Geophysicist John Bellini says he looked at the nearby seismometers and was unable to detect anything Tuesday night. He says they are considering putting a seismometer in Clintonville to get a better reading of potential activity.
He says it's likely a swarm of small earthquakes, which happen several times a year across the country.
Kuss told TODAY'S TMJ4's Nick Montes that the city would talk to USGS staff members about the booms. The federal agency will use satellites to learn more.
"It was just a big boom."
At Schultz' Bluebird Cafe in Clintonville, the house specials weren't the only discussions on the table.
"I thought this morning I heard a couple of them," said Merritt Sasse.
Cathy Sexton heard them as well.
"It was just a big boom and it came from (the) direction (near) the industrial park, or the other side of Main Street."
"My daughter came to pick up her son, and we all heard it. It was just a big boom."
Five minutes after hearing the first one, about 10:30 a.m., it scared Cathy's daughter.
"She said, 'I felt the house shake. I'm getting out of here.' "
