Carla Knecht felt it just before midnight.
“My husband said my name a couple times and then he said, ‘Are you OK?’ And I said, ‘yeah,’ and we both said, ‘What was that?’”
What they felt was a vibrating jolt. It lasted about 5 seconds. They felt their bed and the house shake. They heard a low rumble.
“I’ve never felt that before, thank God,” Knecht said, “and I hope I never do again.”
But they’re OK, and so is their house. It’s about 7 miles west of the small town of Bowdle in north-central South Dakota.
Geophysicist Don Blakeman said the Tuesday night earthquake’s magnitude was 3.2, well below moderate severity.
