For the second time in less than 30 days, the U.S. Geological Service has detected a small earthquake in South Dakota.

The U.S. Geological Survey recorded a 3.1 magnitude earthquake about 3.7 miles north-northeast of Tyndall at 7:55 a.m. Monday, Jan. 4. No other details were immediately available, according to the geological survey.

Tyndall is a community of more than 1,000 people in southeastern South Dakota. It’s about 27 miles northwest of Yankton.

This comes less than a month after the USGS reported a 3.2 magnitude earthquake near Bowdle in north-central South Dakota Dec. 8.
