A series of loud booms frightened residents and caused damage to a home south of Guthrie on Friday.
The Logan County Sheriff's Department said there were multiple calls throughout the day reporting the explosions, but deputies were unable to locate any smoke or debris.
Nancy York, who lives about four miles south of Guthrie, said she began hearing what she described as “loud booms” about 10 a.m. and continued to hear them until after 6 p.m.
At 6:20 p.m. a 3.1-magnitude earthquake was measured four miles south of Guthrie and 11 miles northeast of Edmond, the U.S. Geological Survey reports.
The USGS reported four smaller earthquakes in the same area throughout the day.
York said she found cracks in her walls, floors and front porch after the booms.
“I would hear the explosions and then my whole house would shake,” she said. “Usually when there are earthquakes, there's no loud sound like that.”
York said she called the sheriff's office several times before they came to her house to investigate. When they came, she said, there was another boom that shook the house again.
She said officers couldn't give any explanation other than earthquakes.
According to the U.S. Geological Survey, earthquakes near the surface can cause boom-like sounds.
