Arkansas Feels Another Round Of Quakes

News

BERGMAN, Ark. – Residents in Boone County, Arkansas felt another round of aftershocks Thursday night the largest 2.9 in magnitude.

The Arkansas Geological Survey says since Sunday’s 3.6-magnitude quake, there have been nearly 15 total earthquakes centered in the Bergman area.

The AGS is exploring a theory the rapid increase in the level of Bull Shoals Lake this year is playing a role. It’s a phenomenon known as “reservoir induced seismicity.”

AGS assistant director, Scott Ausbrooks, says crews will be installing seismographs in the ground in the Bergman area Saturday in hopes of highlighting a fault and its direction.

“Then gain an understanding of, ‘well, is that fault in close proximity or connected to the lake?’ If that’s what the data shows,” says Ausbrooks.

“Again, it’s possible this is completely natural and not related to the lake,” he says. “But it’s definitely something we have on our radar.”

Ausbrooks says the data from the new seismographs should be available to the public early next week.

That information can be found at the Arkansas Seismic Network.
