Scientists are stumped why quakes keep hitting this small South Carolina town

David Horne remembers exactly where he was when the first earthquake hit his town of Elgin, S.C., on Dec. 27, 2021.

He was relaxing on his front porch, while his wife was inside caring for their young grandson. Suddenly, Horne felt the ground shake and heard a noise like thunder boom across the sky.

"And as soon as it happened, I got out of my chair and I went and told her, 'That was an earthquake. That was a 3-point-plus,'" he said.

Horne used to live in Alaska, where earthquakes are more common, but his wife, Whitney Horne — a lifelong South Carolinian — said she wasn't sure what had happened.

"Because I'd never experienced an earthquake," she said. "We're in South Carolina! You don't have earthquakes that you feel in South Carolina."

Sure enough, it was a 3.3 magnitude earthquake — too small to cause damage but big enough to light up the town's Facebook page with dozens of excited comments.

At first, David Horne said, he thought it was cool.
