ALLEN — A small 2.5 magnitude earthquake struck near Allen Sunday night, according to U.S. Geological Survey.

Austin A. Holland, a seismologist with the Oklahoma Geological Survey (OGS) in Norman, said the quake comes as no surprise to him.

“We had over 50 earthquakes this weekend,” Holland said. “This year, we’ve had over 700 earthquakes.”

Although the U.S. Geological Survey listed the earthquake at 10:21 p.m. one mile south of Allen, Holland said the OGS in Norman has more recording instruments in Oklahoma and the exact location could change a bit.

“They don’t use as many instruments in the area as we are using at the moment, so it could be located somewhere quite a bit different,” Holland said. “We should have more information on where it was located later this morning on our Website.”

Allen police said they did not receive any reports of damage or injuries or even anyone feeling the quake. Allen resident Shannon Wofford said something strange happened where she lives near the area.

“I remember the front door rattling,” Wofford said. “I thought it was a burst of wind and Tanner (her son) said the motion light went on and off a couple of times. We thought it odd but just blew it off. We thought it was the dogs making the light do that. Just before that happened all of the dogs went berserk.”

Although experts agree earthquakes are more frequent recently, they aren’t sure why.

“We’re seeing several different swarms of activity,” Holland said. “We’ve had swarms earlier this year in Coal County and of course Oklahoma County.”

Holland said when he started at the OGS, many blamed the activity on oil and gas production. While he hasn’t ruled out the oil and gas production theory, Holland said he’s leaning more towards natural occurrences.

“I’ve looked at the earthquakes and they are much more complicated than that,” Holland said. “(From) what I’ve learned about them so far, they certainly appear to be a natural phenomenon and very far from what we consider normal for Oklahoma earthquakes.”
