During the lunch hour on Tuesday, Cathy Kliewer was baking with a neighbor on Birdsong not far from the Kelly-Coffee Creek intersection.
All of a sudden, she heard what sounded like a sonic boom or a natural gas-caused explosion and the house shook just for a moment. Seconds later, it happened again in a similar fashion, both the sound and the shaking.
Kliewer called 911 and asked the dispatcher, “What was that boom?”
While she was on the phone the dispatcher was getting another call about the sound from someone in the vicinity of Second Street and Bryant. On local scanner traffic, several Edmond first responders reported hearing the sound. The incident went over the radio as an explosion heard outside a structure on Birdsong.
Up and down the street, neighbors came out of their homes and wondered what had happened. Tonya Coffman said after hearing the sound and feeling her house shake she thought about the Oklahoma City bombing.
Edmond Fire Department personnel responded to the scene and residents said they suspected an earthquake was the culprit.
That belief has been confirmed by the Oklahoma Geological Survey, which according to preliminary information reports that at 12:53 p.m. a magnitude 2.7 earthquake in Oklahoma County was recorded by 13 seismic stations. A north-south fault line runs just to the west of where the quake occurred.
It was the strongest Oklahoma County quake since a 2.7 magnitude temblor was recorded on Oct. 30. During the interim period, several weaker quakes have been recorded in the county.
